(Grand Bahama I.; Eleuthera I.); Turks & Caicos Is.; Dominican Republic; Puerto Rico; Honduras (Vivorillo Cays); Antigua; Guadeloupe; Martinique; St. Vincent & the Grenadines; Granada; Barbados; Trinidad & Tobago (Tobago I.); Venezuela (Tortuga I.); Netherlands Antilles (Curaçao I.); and French Guiana. Specimens reported as <i>Cerodrillia perryae</i> in Jong & Coomans (1988: 112) are believed to be this species on the basis of a photograph of a specimen from Curaçao I. provided by M. Faber (pers. comm. 22 Apr 2011). <i>Douglassia antillensis</i> is associated with coral reefs and has been reported from 7–32 m depths on carbonate sand or carbonate sand and coral rubble in reef swales or pockets. Only dead-collected specimens occur at greater depths from off Palm Beach Co. (55 m), from off Barbados (128– 183 m), off Curaçao (244–274 m), and off French Guiana (57–103 m), perhaps transported there from shallower depths by currents.</p> <p> <b> Description. <i>Shell</i></b> small (to 17.7 mm), stoutly fusiform, glossy, truncated anteriorly, whorls up to 11, but more commonly around 9; last whorl approximately 63% of total length; whorls convex with bulging ribs; shell apex acutely pointed. <i>Protoconch</i> conical, of approximately 2½–2¾ glassy, smooth whorls, the exact number difficult to determine because the tip of the first is partially immersed in the second; color golden brown. <i>Axial sculpture</i> of prominent convex ribs, obsolete or absent in sulcus, most prominent and widest on whorl periphery a little below mid-whorl, and evanescent on the shell base below periphery. Rib crests round at whorl periphery but ridged in the sulcal region where ribs are narrower and slightly hooked to the left reflecting outline of anal sinus. Ribs number 8–9 on penultimate and 5–7 on the body whorl to the varix. Axial growth striae present on shell surface, curved in the region of the anal sulcus. <i>Varix</i> located just behind the anal sinus and resembles a cup handle when viewed ventrally. <i>Anal sinus</i> on shoulder adjacent to suture, deep, U-shaped, offset from the shell axis by parietal callus; edge of inner lip of sinus flared. <i>Spiral sculpture</i> of fine threads or ridges, barely visible below the periphery of last whorl, becoming stronger anteriorly on base and anterior fasciole. <i>Outer lip</i> thin, projecting out from the varix; with an irregular axial fold or thin axial rib; edge flexed out at anal sinus, waved below; with a shallow stromboid notch. <i>Inner lip</i> wide, margined, thick anteriorly, thinner on parietal wall, with a thick callus that forms one side of the anal sinus. Lip and callus edge raised by visible layers of successive deposition, especially in more mature specimens. <i>Anterior canal</i> short, open, unnotched, slightly curved to the right viewed ventrally, canal tip with a slightly flared marginal lip. Anterior fasciole not swollen; with about 6 faint spiral ridges. <i>Color</i> shell base dingy white, with a light to dark golden brown band just below body whorl periphery, visible as a narrow band at spire sutures; rib crests dingy white; band’s posterior edge fades to the shell’s base color; the anterior edge is more distinct.</p> <p> <b> Remarks. <i>Taxonomy</i>.</b> <i>Douglassia antillensis</i> has all the key characteristics of the genus: a concave sulcus with obsolete or absent ribs, a 2½- to 2¾-whorl protoconch, spiral microsculpture confined to the base, and a cuphandle-like varix positioned immediately behind the anal sinus. It is the commonest <i>Douglassia</i> in the Antilles, often misidentified as <i>Cerodrillia perryae</i> (Bartsch & Rehder, 1939) in museum collections. Many of the published reports of <i>C. perryae</i> from outside of Florida are also likely this species but cannot be confirmed without accompanying photographs. A list of reports of <i>C. perryae</i> that are likely this species is given in the synonymy list under that species. <b> <i>Variability</i>.</b> The average total length of 210 measured specimens is 9.72 mm (2.8–17.7 mm); the average W/ L ratio of 0.449. Given its relatively wide dispersal, it is fairly uniform in its morphology and color pattern, although there are some regional differences in color—those from the northern limit of its distribution, e. g. Grand Bahama I., appear to be lighter in color, and those from the southern limit (French Guiana) a mostly solid orange-brown color with white rib crests. Specimens are shown from various localities in Plate 58. <i> <i>Identification.</i> Douglassia antillensis</i> most closely resembles <i>D. enae</i> Bartsch, 1934 but differs principally in possessing less angular shoulders, most conspicuously on the last whorl. It also differs in coloration; the central band in <i>D. antillensis</i> tends to be less distinct on its adapical (posterior) margin, and its protoconch is dark, similar to the color of the band. <i>Douglassia enae</i> has a more distinct adapical margin on its central band, and a light colored protoconch. Although their ranges overlap, <i>D. antillensis</i> is reported from shallower water. <i>Douglassia antillensis</i> is often misidentified as <i>C. perryae</i> but is stouter, has 2½–2¾ protoconch whorls, not 1¾–2, and a slightly different color pattern. Because it is stouter, its W/ L ratio is greater (Average W/L = 0.449 for 210 specimens of <i>D. antillensis</i> versus 0.392 for the 17 specimens of <i>C. perryae</i>). The color pattern of <i>D. antillensis</i> is consistent among specimens, even across its much larger range than <i>C. perryae</i>. The latter varies in pattern; i.e., the central band is more variable in width, or even absent. <i>Douglassia antillensis</i> differs from <i>D. moratensis</i>, new species in having less convex body whorl, less prominent ribs on the shoulder, and a different color pattern. <i>Douglassia antillensis</i> has also been confused with <i>C. thea</i> (Dall, 1884), but that species’ spire is taller, color a uniform brown, and ribs shorter and more oblique.</p> <p> <b>Etymology.</b> The Antillean <i>Douglassia</i>. Although not strictly confined to the Antilles, <i>D. antillensis</i> appears to be quite common and widespread in this region, especially in the Windward Is.</p>Published as part of <i>Fallon, Phillip J., 2016, Taxonomic review of tropical western Atlantic shallow water Drilliidae (Mollusca: Gastropoda: Conoidea) including descriptions of 100 new species, pp. 1-363 in Zootaxa 4090 (1)</i> on pages 130-133, DOI: 10.11646/zootaxa.4090.1.1, <a href="http://zenodo.org/record/263299">http://zenodo.org/record/263299</a>
Clathrodrillia marissae Fallon, 2016, new species
No full textClathrodrillia marissae, new species (Plate 44) Type material. Holotype 37.1 x 13.7 mm, J. Worsfold! (ANSP 369004). Type locality. Off Tamarind, Grand Bahama I., Bahama Is., 26 ° 30 ' 45 ''N, 078° 36 '00''W, in 183 m. Range and habitat. Known only from the holotype. Description. Shell medium (to 37.1 mm), fusiform, truncated anteriorly, whorls turreted, number at least 9 (shell apex worn, protoconch missing), convex, last approximately 58 % to total length; axial ribs are the predominant sculptural element; anterior canal moderately long. Protoconch is unknown, missing on type specimen. Axial sculpture of narrow, straight ribs, 14 on the penultimate, 8 on last whorl to varix, that run sutureto-suture on spire whorls, evanesce near anterior fasciole of last whorl; narrower than their interspaces; rib crests ridged (not round) and curved in sulcus reflecting outline of anal sinus. Microscopic growth striae dense, visible between spiral cords and in sulcus. Varix hump-like, quite convex; prosocline. Spiral sculpture of evenly spaced grooves forming flat cords that override axials becoming cord-like and nodulose on rib crests, 5 on penultimate, 4 on base posterior to a smooth spiral band without sculpture, then 5 on anterior fasciole. Sulcus wide, concave, with greatly reduced and curved ribs; with microscopic spiral lines but without cords. Outer lip thin, somewhat flattened, with 4 irregular axial folds; exaggerated nodules appear at the intersection of spiral cords and folds. Edge of lip missing so its outline, presence or absence of teeth, and stromboid notch are unknown. Anal sinus a deep Ushaped notch adjacent to suture, edge flared upward. Inner lip moderately wide, recumbent; extending beyond anterior canal anteriorly, thin and recumbent on parietal wall, forming a parietal lobe posteriorly. Anterior canal moderately long, twisted to the right when viewed ventrally; unnotched. Color off-white with an irregular light yellow-brown wash on upper portion of whorls; 3 light to dark brown spiral bands, darkest below shoulder, lightest 2 below suture line and on anterior canal, both visible only on last whorl. Remarks. Taxonomy. Clathrodrillia marissae has a turreted form, a moderately long anterior canal, ribs from suture-to-suture, a hump-like varix with a dark color patch on leading edge of the varix, and a strong spiral sculpture, which are characteristics of Clathrodrillia. This species is unique among its congeners in possessing nodulose cords. Identification. Clathrodrillia marissae is very similar to C. petuchi (Tippett, 1995) but differs in possessing narrower ribs with wider interspaces, spiral ridges that are more cord-like, and a longer anterior canal. Its shell surface is glossy, not dull, due principally to finer growth striae. Although this specimen has a fascies similar to several of its congeners (C. gibbosa, C. petuchi, and C. colombiana), it possesses characteristics not seen in any of the specimens of these three, namely a very fine, almost polished surface, and axial ribs that are comparatively widely separated (see Plate 50). The wide geographic separation of similar congeners (the nearest being C. petuchi reported from as far north as Guadeloupe) is likely an isolating mechanism. Etymology. Named in honor of Marissa, daughter-in-law and mother of my two grandchildren.Published as part of Fallon, Phillip J., 2016, Taxonomic review of tropical western Atlantic shallow water Drilliidae (Mollusca: Gastropoda: Conoidea) including descriptions of 100 new species, pp. 1-363 in Zootaxa 4090 (1) on pages 101-102, DOI: 10.11646/zootaxa.4090.1.1, http://zenodo.org/record/26329

Antilles, M. Coltro!, Sep 2004 (P. Stahlschmidt coll.). Range and habitat. Trinidad & Tobago (Tobago I.; Trinidad I.); Netherlands Antilles (Curaçao; Aruba). Reported from on fine silty sands in a relatively sheltered bay in 9– 24 m. Description. Shell small (to 12.8 mm), fusiform, glossy, translucent between ribs and spiral threads; whorls convex, about 9 ¾ total, the last approximately 57 % of total length; sulcus present, about ¼-whorl height; principal sculptural element of ribs and spiral threads. Protoconch approximately 1 ¾– 2 ¼ whorls, a clearly visible carina arising about ¼-turn from the tip beginning mid-whorl, but is sub-peripheral beginning on 2 nd; the 2 nd whorl is wider than first teleoconch whorl, the protoconch appearing somewhat bulbous. Axial sculpture of numerous narrow, opisthocline ribs, suture-to-suture; recurved in sulcus and extending to anterior fasciole on last, 14–15 on penultimate, 10–13 on last whorl to varix or to varix crest where they often appear; rib interspaces much wider than ribs. Varix broad, hump-like, approximately ⅓-turn from edge of outer lip. Spiral sculpture of flattened threads, interspaces less than thread width, or alternatively, wide grooves evenly spaced creating the appearance of flattened threads, closer and narrower in sulcus; threads override axials giving them a somewhat nodulose appearance. Sulcus convex, with 4–6 closely packed spiral threads, together appearing like a wide subsutural fold. Outer lip flattened from varix to edge of lip thus projecting out from the curvature of the shell in apical view; with up to 5 axial folds; lip edge forms a flat arc from anal sinus to the stromboid notch, and is inflected at anterior canal, bent inward posteriorly. Stromboid notch deep, edge flared. Anal sinus deep, mid-way on whorl shoulder, U-shaped, entrance slightly constricted by callus on parietal wall; outward flare of sinus edge gives the appearance of being spout-like. Inner lip erect anteriorly where a chink forms between it and fasciole on older specimens, recumbent and wider on parietal wall, and formed into a lobe posteriorly; successive growth increments visible on edge of lip. Anterior canal open, moderately long, turned to the right when viewed ventrally; canal end upturned, and notched asymmetrically across its width. Anterior fasciole slightly swollen with spiral threads on surface forming a marginal ridge along its adapical edge. Color pink with light orange-yellow maculation between ribs in the sulcus; flesh-colored with light brown between ribs in the sulcus; brownish-pink with a whitish mid-whorl band and rib crests, sulcus and above suture darker, apex pink and a brown stain on the varix, or lavender pink with light brown between ribs in the sulcus and a brown-stained varix. Remarks. Taxonomy. Calliclava tobagoensis has all of the characteristics of the genus: numerous ribs that extend from suture-to-suture with a distinctly delineated sulcus, conspicuous spiral grooves (threads) across intercostal spaces, and a protoconch with both whorls carinate. Variability. The average total length of 54 specimens is 10.79 mm (7.2–12.8 mm) and their average W/ L ratio is 0.392. Specimens vary in color by locality (of examined specimens); those from Store Bay, Tobago I. are brownish-pink, have a whitish mid-whorl band and rib crests, darker sulcus, pink apex; and brown-stained varix. Those from Maracas Bay, Trinidad I. are lavender pink and have light brown between ribs in the sulcus, and a brown stained varix. Specimens from the latter locality are stouter than those from the former. The Trinidadian 14 have an average W/ L ratio of 0.406, compared to the slimmer W/ L ratio of 0.386 of the 39 Tobagoan specimens. These differences in color and form are not believed to merit their separation at species level, but further study is merited. Identification. Calliclava tobagoensis may be confused with Agladrillia rhodochroa (Dautzenberg, 1900), which is similar in size, color, and sculpture. The distinctions are that A. rhodochroa has a smooth almost translucent last whorl dorsum, without axials, the varix precedes the edge of the outer lip by about ½-turn, and has a “pinched” anterior canal, unlike the more even tapered one of C. tobagoensis. Calliclava tobagoensis is also similar to C. fasciata, new species but differs in being smaller, differently colored, and has some minor differences in shell morphology. The average total length of C. tobagoensis is 10.8 mm versus 16.70 mm for the larger C. fasciata. Calliclava tobagoensis has a fairly uniformlycolored shell with maculations in the intercostal spaces on whorl shoulders; C. fasciata has a white shell with a wide, mid-whorl spiral color band. From Calliclava vigorata, new species it differs in being smaller (average total length of 10.80 mm versus 14.08 mm), in possessing a narrower last whorl and an anterior canal that is straighter, not bent as much to the right as in C. vigorata, when viewed ventrally. Etymology.

Clathrodrillia colombiana Fallon, 2016, new species
No full textClathrodrillia colombiana, new species (Plate 39) Type material. Holotype 44.4 x 17.9 mm, J. Poulos! 1991 (UF 470280). No paratypes. Type locality. Off Cabo de la Vela, Guajira Dept., Colombia, in 200 ft [61 m]. Range and habitat. Colombia (off Guajira Dept.). If the specimens illustrated in Daccarett & Bossio (2011) and K. & L. Sunderland (1999 c) are this species, then its range would include Magdalena Dept., Colombia and the Gulf of Venezuela, respectively. The single reported depth is 61 m. Description. Shell medium (44.4 mm total length; may be to 59 mm, if the Sunderland & Sunderland 1999 c report is this species), fusiform with a tall, turreted spire, and narrow, moderately long anterior canal; suture appressed, made somewhat [wavy] over previous whorl’s ribs; whorls straight-sided on spire, number approximately 10 total, the last 58 % of total shell length. Sculpture of numerous ribs cut by closely spaced grooves; aperture narrow. Protoconch unknown, missing on holotype. Axial sculpture of numerous narrow ridge-crested ribs (18 on penultimate and 11 on last whorl to varix), straight on spire whorls, slightly sigmoidal on last whorl where they narrow and evanesce on shell base to anterior fasciole. Ribs end abruptly at sulcus, producing squareangled shoulders, extending to suture only as raised lines, or traces not much larger than growth striae. Varix low, broad, hump-like, positioned approximately ⅓-turn from edge of outer lip. Appearing like a series of ribs only partly fused. Spiral sculpture of deep, closely-spaced grooves that result in cord-like spirals overriding ribs. Cords are somewhat ridged (squared rather than round) on their abapical sides, number 5 on penultimate, 15 on last whorl, and 8 more shallow, closely spaced grooves on anterior fasciole. Sulcus flat, wide, with coarse, curved growth striae along with rib traces, and fine spiral grooves that are mostly masked by the ribs and growth striae. Outer lip slightly flattened from varix to its edge such that it protrudes beyond the shell’s circumference; has approximately 10 irregular axial folds; edge forms a low arc from anal sinus to anterior canal with only a slight indentation marking the stromboid notch. Teeth are absent but spiral grooves appear scalloped when viewed ventrally. Anal sinus a deep U-shaped notch offset laterally by the parietal lobe such that it appears spout-like. Inner lip margined, recumbent on parietal wall, erect anteriorly, formed into an elongate lobe on the parietal side of the anal sinus posteriorly. Anterior canal moderately long, open, turned to the right when viewed ventrally, slightly notched; fasciole not swollen. Color yellow-brown overall; aperture, fasciole, and rib crests on shoulder white; brown patch on varix. Remarks. Taxonomy. Clathrodrillia colombiana has all of the characteristics of Clathrodrillia: strong spiral sculpture, ribs that are angled at whorl shoulders giving it a turreted outline, a hump-like varix, and narrow aperture with a moderately long anterior canal and spout-like anal sinus. Identification. Clathrodrillia colombiana is most similar to C. gibbosa (Born, 1778) and C. petuchi (Tippett, 1995). It differs from C. gibbosa in being stouter (shorter spire), and broader (W/L = 0.403 versus avge. W/L = 0.371), and in being colored differently. From C. petuchi it differs in having more ribs (18 versus 13–15 on the penultimate whorl), deeper spiral grooves over its shell surface, and in being colored differently. Although this taxon is based on a single specimen, it is uniquely different from its most similar congeners as explained above. Specimens of C. gibbosa from Colombia do not resemble C. colombiana and thus the latter is not a geographic varient. Furthermore, illustrations in Daccarett & Bossio (2011) and Sunderland &. Sunderland (1999 c) are clearly of this species, being similar in appearance, and thus giving evidence that supports the constancy of and validity of this species. Etymology. The Colombian Clathrodrillia.

The Perils of Conceptualism: A Response to Professor Fallon
No full textI am grateful for Professor Fallon\u27s constructive and lucid remarks. They are thoughtful and perceptive. But they also reveal the limitations of the kind of highly conceptualist focus that has unfortunately come to characterize so much of our modern constitutional scholar-ship. Fallon argues that what I identify as the paradox of public dis-course can be dissolved if first amendment doctrine is conceived within the framework of Rawlsian liberalism. He contends that from the perspective of that liberalism, members of a particular community can believe that behavior is outrageous and therefore reprehensible while simultaneously believing, as members of a national community, . . . that their own illiberal moral norms ought not to enjoy the sanction of law. If this is so, Fallon concludes, denying the sanction of law to . . . illiberal norms does not corrode the necessary foundation [of] liberal norms for critical public discourse to occur. There is, in short, no paradox. Fallon is, of course, quite correct that there is no logical inconsis-ency between the existence of community norms and the need for public toleration. But the limitations of this point become obvious as soon as it is seen that law does not exist merely on the conceptualist plane of logic and theory, but serves also as a practical instrument for the governance of society. The paradox of public discourse does not flow from the incompatibility of abstract ideas, but rather from the sociological tensions inherent in the dynamic functioning of the law
Cerodrillia porcellana Fallon, 2016, new species

Aug–Oct 1952 (DMNH 240354); 17 paratypes from the type locality: 2 spec., 7.4 x 3.0 & 8.0 x 3.0 mm, (DMNH 240356); 3 spec., 7.4 x 2.8, 7.7 x 3.0, and 4.7 x 2.5 mm, (MCZ 279174); 3 spec., 7.6 x 2.3, 8.0 x 3.1, and 7.4 x 2.2 mm, (ANSP 323999); 1 spec., 6.0 x 2.6 mm (UF 21573); 7 spec., 9.0 x 3.7, 7.7 x 3.0, 8.0 x 3.3, 7.7 x 3.0, 6.7 x 2.6, 8.8 x 3.5 & 6.1 x 2.9 mm (UF 158086). A single paratype, 10.6 x 4.2 mm, is from Campeche Bank off Yucatan, “Station 1244 ”, L. Kornicker! (USNM 667765). Type locality. 32–56 km ENE to NNW of Arcas Cays, Campeche Bank, Gulf of Mexico, in 44– 48 m. Range and habitat. Campeche Bank. Specimens have been reported from 16–48 m depths, from on mud or sandy mud. Description. Shell small (to 10.6 mm), broadly fusiform, glossy, truncated anteriorly with a narrow canal; body whorl approximately 60 % of total length. Whorls convex, sutures impressed but undulant over ribs of the previous whorl. Protoconch paucispiral with 1 ½– 2 smooth glossy whorls. Axial sculpture of broad ribs that extend from suture-to-suture on spire whorls but fade on shell base; 9–11 ribs on the penultimate and 7–10 on last whorl to varix. Ribs with ridged, not rounded crests; slightly recurved in sulcal area. Spiral sculpture limited to ridges on shell base below whorl periphery, strongest on anterior fasciole. Sulcus absent, shoulders with a slight recurve in the ribs just below suture. Varix an expanded rib, cup handle shaped, positioned behind the anal sinus. Outer lip thin, edge extending in a smooth arch from, and congruent with the anterior edge of the anal sinus, to the anterior canal; stromboid notch close to the anterior end and just a ruffle in the lip’s edge. A short narrow axial fold present between varix and edge of outer lip. Anal sinus on shoulder, shallow, sides divergent. Inner lip moderately wide, emarginated and erect anteriorly with a parietal callus joining the outer lip at the suture. Anterior canal short, open, and unnotched; anterior fasciole not swollen. Color porcellaneous white. Remarks. Nomenclature. Multi-specimen lots given the name “ Cerodrillia arcas ” by Dan Steger were distributed to museums in anticipation of publication of their description (around 1970). Lots deposited by Steger were found in ANSP, FLMNH, MCZ and DMNH, and perhaps others exist. They are typically a mix of juvenile and adult specimens, with juvenile and adult specimens of Lissodrillia arcas, new species mixed in (additional detail under the description of that species). Juveniles of the two are difficult to distinguish and most in poor condition, so some juveniles of C. porcellana were likely left out of the type series given above. Taxonomy. Cerodrillia porcellana has all the shell characters that are diagnostic of Cerodrillia, including suture-to-suture axial ribs, a cup-handle-like varix just behind the anal sinus, and a polished shell surface with faint spirals confined to the shell base. Its whorl shoulders are less well defined than most of its congeners. Variability. The average total length of 18 specimens is 7.67 mm (4.7–10.6 mm), and their average W/ L ratio is 0.392. Identification. Cerodrillia porcellana is usually distinguished from known congeners by its pure porcelain-white color. C. porcellana is similar to C. yucatecana, new species, C. occidua, new species, and C. sanibelensis, new species. Cerodrillia yucatecana differs in possessing ribs with round, not ridged crests, a longer more tapering anterior end, and a different color—white to pale golden brown, not porcellaneous white. Cerodrillia occidua differs in possessing more convex ribs and sigmoid ribs, and is generally larger (11.20 versus 7.67 mm, average length). From to C. sanibelensis it differs in having more evenly rounded and more numerous ribs (9–11 versus 6–7 on the penultimate whorl). Etymology. The Porcellaneous Cerodrillia. The minor epithet is from the Neo-Latin porcellanus meaning of porcelain. The shell color and glossy surface are reminiscent of pure white bone china.Published as part of Fallon, Phillip J., 2016, Taxonomic review of tropical western Atlantic shallow water Drilliidae (Mollusca: Gastropoda: Conoidea) including descriptions of 100 new species, pp. 1-363 in Zootaxa 4090 (1) on pages 77-79, DOI: 10.11646/zootaxa.4090.1.1, http://zenodo.org/record/26329

Calliclava fasciata Fallon, 2016, new species
No full textCalliclava fasciata, new species (Plate 17) Type material. Holotype, 16.1 x 6.0 mm (UF 470272); 2 paratypes: 1 spec., 17.3 x 6.6 mm, in 6 m, Los Roques, Venezuela (USNM 1291323); 1 spec., 17.6 x 6.8 mm, in 22–25 m, off Cabo Codera, Miranda State, Venezuela (P. Stahlschmidt coll.). Type locality. Arenas Point, Tortuga I., Venezuela, in 8 m. Range and habitat. Venezuela (Tortuga I.; Los Roques Is.). If the specimen depicted in Daccarett & Bossio (2011, species 787) is this species, then its range would include Colombia. Specimens from Venezuelan localities were taken from 6–25 m depths. The Colombian specimen, if proven to be this species, was reported from 44 m. Description. Shell small (to 17.6 mm total length), fusiform, glossy, translucent between ribs and spirals; whorls convex, about 10 ½ total, the last approximately 56 % of total length; sutures impressed; principal sculptural element of ribs and spiral threads. Aperture narrow, widest posteriorly near anal sinus. Protoconch approximately 2 ¼– 2 ½ translucent whorls, a clearly visible carina present on both whorls beginning mid-whorl on the first, subperipheral beginning on 2 nd to end of protoconch. Axial sculpture of numerous narrow, opisthocline ribs, that extend from suture-to-suture, are recurved in sulcus, and run to anterior fasciole on last whorl; whorls number 14– 16 on penultimate, 9–12 on last whorl to varix; rib interspaces much wider than ribs. Growth striae present over entire shell, most visible between spiral threads. Varix broad, hump-like, approximately ⅓-turn from edge of outer lip. Spiral sculpture of flattened threads, interspaces less than thread width, or alternatively, wide grooves evenly spaced creating the appearance of flattened threads, closer and narrower in sulcus; threads override axials giving them a somewhat nodulose appearance; threads number 6 on penultimate and 15 on last whorl to anterior fasciole. An additional 7 present on fasciole. Sulcus convex, about ¼- to ⅓-whorl height with 3 spiral threads in addition to axial ribs that are narrowed, educed, and recurved. Outer lip flattened from varix to edge of lip thus projecting out from the circumference of the shell in apical view; with 4 axial folds; lip edge forms a flat arc from anal sinus to the stromboid notch. Stromboid notch deep, edge flared. Anal sinus deep, positioned whorl shoulder, U-shaped, entrance slightly constricted by callus on parietal wall; upward flare of sinus edge and outward curve of outer lip gives the appearance of being spout-like. Inner lip erect anteriorly, recumbent and wider on parietal wall, and formed into a lobe posteriorly; incremental growth layers visible at edge of lip. Anterior canal open, narrow, moderately long, turned to the right when viewed ventrally, upturned slightly at its tip, and notched. Anterior fasciole not swollen. Color white with a wide yellow-brown band mid-whorl, which appear on the bottom half of spire whorls, and darker brown patch on varix. Aperture light violet, which shows through the outer lip. Remarks. Taxonomy. Calliclava fasciata has all of the characteristics of the genus: numerous ribs that extend from suture-to-suture with a distinctly demarcated sulcus, conspicuous spiral threads across intercostal spaces, and a protoconch with both whorls carinate. Variability. The 3 specimens have an average total length of 17.00 mm (16.1–17.6 mm) and an average W/ L ratio of 0.377. Identification. Calliclava fasciata is similar to C. vigorata, new species. It is somewhat larger (17.00 versus 13.11 mm average total length), has a yellow-brown mid-whorl band (C. vigorata is usually white), and not as stout (average W/L = 0.377 versus 0.399). From C. tobagoensis, new species it differs in size, coloration, and minor details of surface sculpture. Calliclava fasciata is larger (17.0 versus 10.8 mm average total length), and has a white shell with a wide, mid-whorl spiral band of color; C. tobagoensis has a more uniformly colored shell with maculation in the intercostal spaces on the whorl shoulders. Etymology. The Banded Calliclava; named for the prominent yellow-brown mid-whorl spiral band present on all specimens examined. From the Latin adjective fasciata meaning having a band.Published as part of Fallon, Phillip J., 2016, Taxonomic review of tropical western Atlantic shallow water Drilliidae (Mollusca: Gastropoda: Conoidea) including descriptions of 100 new species, pp. 1-363 in Zootaxa 4090 (1) on pages 47-48, DOI: 10.11646/zootaxa.4090.1.1, http://zenodo.org/record/26329
