    "The Return of Big Government--Policy Advice for President Obama"

    Get PDF
    In the current global financial crisis, economists and policymakers have reembraced Big Government as a means of preventing the reoccurrence of a debt-deflation depression. The danger, however, is that policy may not downsize finance and replace money manager capitalism. According to Senior Scholar L. Randall Wray, we need a permanently larger fiscal presence, with more public services. His advice to President Obama is to discard all of former Treasury Secretary Paulson's actions. Wray believes that we can afford any necessary spending and bailouts, and that these actions will not burden our grandchildren.

    Effects of staphylococcal enterotoxin A on impulsivity and spatial cognition in C57BL/6 mice

    No full text
    Background & Aims: Bacterial antigens have shown to cause cognitive deficits and impulsivity in mice that has been thought to be the result of an activated immune system. However these findings could be due to other factors, such as sickness behavior, which could interfere with the behavioral assessments of cognition and impulsivity. Staphylococcal enterotoxin A (SEA) is a bacterial superantigen that does not induce sickness behaviour in mice. The aim of this study was to investigate the effects of SEA on spatial cognition and impulsivity. Methods: Saline or SEA (5 µg i.p) was injected in C57BL6 mice (n=8 per group). Changes in impulsivity were assessed on a 24-32 second differential reinforcement of low response rates schedule of reinforcement and changes in cognition were assessed with the Morris water navigation task (hidden platform and probe trial) after a single or repeated injections of SEA. Results: SEA significantly decreased the number of food pellets mice earned (P= .01) but showed no effect on efficiency ratios (reinforced nose pokes / total nose pokes) with respect to controls, when tested on the DRL schedule. Compared with controls, SEA also increased stereotypy like behavior in mice, with increased responding after food reinforcement (P=.001) in the DRL schedule. Morris water navigation task showed decreases in latency and distance traveled to reach platform across days both in single (P< 0.05) and repeatedly (P<0.005) injected mice. However no differences in performance were seen between SEA and controls. Conclusion: Injection of SEA does not affect spatial cognition or induce impulsive behavior in mice; however, SEA induces behavioral changes similar to stereotypy.M.S.Includes bibliographical referencesby Randall Thomas Woodruf

Hastings, the thesis advisor of the first author, who initially aroused the first author&rsquo;s curiosity in clingfishes.&lt;/p&gt; &lt;p&gt; &lt;b&gt;Remarks:&lt;/b&gt; Randall (1996) published a book entitled &lt;i&gt;Coastal Fishes of Oman&lt;/i&gt;. Fish collections for this volume include a single specimen of a clingfish taken in 1993 that he was unable to identify to genus or species. We are aware of no additional material of this species, which is so distinctive that we no longer hesitate to describe it from a single specimen.&lt;/p&gt; &lt;p&gt; Shiogaki &amp; Dotsu (1983) reported on the head sensory canal pores of the Gobieosocidae and proposed that the orientation and number of these pores may be useful to differentiate clingfish genera. The pattern observed in &lt;i&gt;B. hastingsi&lt;/i&gt; (nasal canals 2, postorbital canals 1, lachrymal canals 2) would indicate a close relationship with species of the genera &lt;i&gt;Pherallodus&lt;/i&gt; and &lt;i&gt;Parvicrepis&lt;/i&gt; of the subfamily Diplocrepinae. Species of the Diplocrepinae, however, have gill membranes that are free from the isthmus, thus &lt;i&gt;B. hastingsi&lt;/i&gt; with its attached gill membranes is placed in the Aspaminae, following Briggs (1955). Briggs (1993) described a new genus and species, &lt;i&gt;Posidonichthys hutchinsi&lt;/i&gt;, which also possesses three gills, a double disc, and gill membranes that are attached to the isthmus, indicating its placement within the Aspasminae. However, Briggs noted several characters in the general osteology of &lt;i&gt;P. hutchinsi&lt;/i&gt; that suggest a close relationship to the Diplocrepinae. The relationship of these two subfamilies is in need of further study.&lt;/p&gt; &lt;p&gt;Body Depth 6.1&lt;/p&gt; &lt;p&gt;Body Width 4.6&lt;/p&gt; &lt;p&gt;Head Length 2.5&lt;/p&gt; &lt;p&gt;Head Width 3.9&lt;/p&gt; &lt;p&gt;Snout Length 6.5&lt;/p&gt; &lt;p&gt;Orbit Diameter 16.0&lt;/p&gt; &lt;p&gt;Interorbital Width 13.9&lt;/p&gt; &lt;p&gt;Upper-jaw Length 6.3&lt;/p&gt; &lt;p&gt;Caudal-peduncle Depth 16.0&lt;/p&gt; &lt;p&gt;Caudal-peduncle Length 13.9&lt;/p&gt; &lt;p&gt;Predorsal Length 1.2&lt;/p&gt; &lt;p&gt;Preanal Length 1.3&lt;/p&gt; &lt;p&gt;Longest Dorsal-fin Ray 18.9&lt;/p&gt; &lt;p&gt;Longest Anal-fin Ray 20.8&lt;/p&gt; &lt;p&gt;Caudal-fin Length 7.7&lt;/p&gt; &lt;p&gt;Pectoral-fin Length 10.4&lt;/p&gt; &lt;p&gt;Dorsal-caudal Distance 5.3&lt;/p&gt; &lt;p&gt;Postdorsal-caudal Distance 8.3&lt;/p&gt; &lt;p&gt;Disc Length 3.9&lt;/p&gt; &lt;p&gt;Disc Width 4.4&lt;/p&gt;Published as part of &lt;i&gt;Craig, Matthew T. &amp; Randall, John E., 2009, Briggsia hastingsi, a new genus and species of clingfish from Oman, pp. 64-68 in Zootaxa 2271&lt;/i&gt; on pages 65-67, DOI: &lt;a href="http://zenodo.org/record/190974"&gt;10.5281/zenodo.190974&lt;/a&gt

Plectranthias kelloggi [non Jordan & Evermann 1903].— Sih et al. 2017: table 1 (central Great Barrier Reef). Diagnosis. The following combination of characters distinguishes P. retrofasciatus from congeners: dorsal rays X,15–17, third spine longest; pectoral rays 13, most rays branched; lateral line complete, with 27–30 scales; two enlarged antrorse serrations on lower edge of preopecle; greatest body depth 36–42 % SL. Remarks. This species was originally described by Fourmanoir & Randall (1979) from the 61.8 mm SL holotype collected in 200 m at Gazelle Pass, New Caledonia. In 1986, the first author identified a second, 16.0 mm SL specimen collected in 194 m off Lady Elliot Island, southern Great Barrier Reef (AMS I.26844-001). The Lady Elliot specimen was overlooked in subsequent faunal checklists and accounts on Australian Plectranthias. Aside from differences that can be attributed to its much smaller size, the specimen agrees well with the holotype, including the presence of a tapered bar extending from the middle of the dorsal fin to the anterior anal fin, and a second band on the caudal peduncle (Figure 40A). Randall & Hoese (1995) described P. pallidus from the holotype from off Townsville, Queensland, which they named for its pale preserved coloration and apparent lack of pigmentation. We located a second specimen that closely resembles the P. pallidus holotype and was collected on the same voyage from almost the same locality and depth (Figure 40B). Randall & Hoese compared P. pallidus only with P. wheeleri, and not with P. retrofasciatus. Randall (1996) differentiated P. retrofasciatus from subsequent species in his key (including P. pallidus) on the basis of coloration (presence versus absence of two sharply defined red bars, one on body through notched portion of dorsal fin and the other through caudal peduncle) and lower jaw dentition (inner row teeth about twice as long as those in outer rows versus about same size as outer row teeth). White et al. (2013) and Peristiwady et al. (2014) recorded P. retrofasciatus from Indonesia on the basis of market specimens from Lombok and northern Sulawesi, respectively. Y.K. Tea (pers. comm.) brought to our attention an additional Indonesian specimen (from Java) that entered the marine aquarium fish trade (Figure 41A). There are two specimens in the CSIRO collection, which formed the basis of White et al. ’s record, one of which was photographed when fresh (Figure 41B). When examined in Feb 2020, the photographed specimen was very pale, with only a weak indication of the red bars and other markings persisting as scattered fine melanophores (Figure 41C). These markings were even less obvious in the other CSIRO specimen. Peristiwady et al. also noted that their specimens were pale following preservation. Suspecting that P. pallidus may be referable to P. retrofasciatus, we re-examined the holotype and non-type specimen from off Townsville. We found that they not only had very faint indication of the mid-body and caudal peduncle bars, but the enlarged inner row teeth in the lower jaw characteristic of P. retrofasciatus. We found no other substantial differences between the specimens, and therefore place P. pallidus in the synonymy of P. retrofasciatus. Sih et al. (2017) recorded P. kelloggi from the central Great Barrier Reef (ca 18°12′S, 147°15′E and 18°15′S, 147°23′E) based on video footage from baited cameras in 155–179 m, but their observations also appear to be referable to P. retrofasciatus. Based on Randall’s (1980) treatment of P. kelloggi, Sih et al. ’s record of P. kelloggi would indicate the presence of P. melanesius (otherwise P. azumanus – see Remarks for P. melanesius). However, the fishes in their footage have two red bars on the posterior body, the anterior of which is relatively narrow, slopes posteroventrally and tapers ventrally. This agrees well with the condition found in P. retrofasciatus. In contrast, the anterior bar in P. azumanus and P. melanesius is more or less vertical, and broad throughout its length. We add the following new observations based on our examination of the Australian and Indonesian specimens: scales with peripheral cteni; vertebrae 10+16; supraneurals 3; predorsal formula 0/0+0/2/1+1; dorsal pterygiophores in interneural spaces 9–13 1/1/1+1/1+1/1+1; no trisegmental pterygiophores associated with dorsal fin; terminal dorsal pterygiophore in interneural space 17–18; no trisegmental pterygiophores associated with anal fin; terminal anal pterygiophore in interhaemal space 5; ribs present on vertebrae 3 through 10; epineurals present on vertebrae 1 through 12–13; parhypural and hypurals autogenous; well-developed hypurapophysis on parhypural; epurals 3; single uroneural (posterior uroneural absent); ventral tip of cleithrum with well-developed posteroventral process; proximal tip of first anal-fin pterygiophore near distal tips of parapophyses on vertebra 10.

Originally a medium for human-readable documents, the next generation Semantic Web is opening up toolkit that provides vast opportunities for sharing information that is encoded in a machine-readable form. The opportunities for sharing data also are opportunities for encroaching on people's privacy. While some technologies already exist for expressing privacy preferences, they do not integrate closely with the Semantic Web. In addition, previous approaches to privacy expression do not easily expand to data shared over multiple hops, with different privacy preferences at each hop. The Private Information Management Agent is an attempt to mitigate these concerns.by Ryan Randall Wagner.M.Eng

    Plectranthias inermis Randall Figures 5A, 23; Tables 1–16, 24 Common name: Checkered Perchlet Plectranthias inermis Randall 1980: 135, fig. 11, tab. 9 (type locality: Caban Island, Batangas, Luzon, Philippines; paratypes from Christmas Island).— Allen & Steene 1988: 180 (checklist, Christmas Island).— Allen 2000: 87 (checklist, Christmas Island).— Hobbs et al. 2014a: 194, tab. 1 (checklist, Christmas Island).— Anderson 2018: 28 (checklist). — Parenti & Randall 2020: 26 (checklist). Diagnosis. The following combination of characters distinguishes P. inermis from congeners: segmented dorsal rays 16–18; third dorsal spine longest, 15.6–18.8 % SL; lateral line complete, interrupted or incomplete, consisting of 12–28 tubed scales; predorsal scales extend anteriorly to middle or posterior interorbital (at point ranging from vertical through posterior edge of orbit to vertical through middle of pupil); preopercle with 3–11 weak serrations on posterior (vertical) edge and 0–2 weak serrations on ventral edge (none antrorse). Remarks. A relatively small species (largest specimen 44.8 mm SL, Heemstra 1980), P. inermis is known in Australia only from Christmas Island. Elsewhere it is widely distributed, ranging from Mauritius in the western Indian Ocean to Fiji in the Pacific (Randall 1980; Heemstra 1996; Heemstra & Randall 2009). Its small size and bright coloration make it desirable as an aquarium fish, and it frequently enters the aquarium trade, often under the names “Geometric Perchlet” or “Geometric Hawkfish” (a misnomer, resulting from confusion with members of the superficially similar Cirrhitidae). Two specimens were obtained by the first author through the US aquarium trade, and subsequently cleared and stained (Taylor & van Dyke 1985). The two specimens form the basis of our summary of osteological features of the species, as radiographs of other specimens lacked adequate detail. Randall (1980, 1996) reported this species as having an incomplete lateral line. However, Heemstra (1996) and Heemstra & Randall (2009) later reported that the species may have an interrupted or complete lateral line. Several specimens examined in this study also have interrupted or complete lateral lines, which consist of 12–28 tubed scales. Katayama & Masuda (1980) described P. altipinnatus from the holotype from the Izu Peninsula, Japan. They compared the species only with P. morgansi (Smith, 1961) from east Africa. However, the species is clearly more closely related to P. inermis, having similar meristic and morphometric details, an elongate third dorsal spine bearing a pennant-like filament, and weak serrations on the preopercle. The two species differ in live coloration details (cf. Figures 23A and 24): P. inermis has a red and white checkered pattern on the body, with the pattern extending on to the posterior abdomen, anal-fin base and caudal peduncle; in contrast, in P. altipinnatus, the upper body is mostly red, from which extend 4–5 short red to yellow bars, with five short red bars ventrally (one on mid-abdomen, one near the anal-fin origin, one near the anal-fin termination, and two on the caudal peduncle). However, a detailed morphological comparison of the two nominal species is required. We have not attempted such a comparison in the present study. We add the following new observations for P. inermis: scales with peripheral cteni; vertebrae 10+16; supraneurals 3; predorsal formula 0/0+0/2/1+1; dorsal pterygiophores in interneural spaces 9–13 1/1/1+1/1/1+1, 1/1/1+1/1+1/1+1 or 1/1/1+1/1+1/1+1+1; no trisegmental pterygiophores associated with dorsal fin; terminal dorsal pterygiophore in interneural space 18; no trisegmental pterygiophores associated with anal fin; terminal anal pterygiophore in interhaemal space 4–5; ribs present on vertebrae 3 through 10; epineurals present on vertebrae 1 through 11; parhypural and hypurals autogenous (Figure 5A); well-developed hypurapophysis on parhypural; epurals 3; single uroneural (posterior uroneural absent); ventral tip of cleithrum with well-developed posteroventral process; proximal tip of first anal-fin pterygiophore near distal tips of parapophyses on vertebra 10.

    Field localization in a modified Randall-Sundrum brane model

    Get PDF
    We consider a modified Randall-Sundrum metric model in a five-dimensional spacetime. The metric is conformally flat, has an exponential warp factor, and is physically distinct from the original Randall-Sundrum metric model. Massless scalar fields are localized on the brane for decreasing warp factor while massive scalar fields are localized on the brane for either decreasing or increasing warp factors. There is an upper bound mass for the decreasing warp factor and there are two possible different masses for the increasing warp factor. For a constant value of the fifth component of the vector matter field we obtain a possible localization for massless vector fields, but not for massive vector fields. Both massless and massive spinor fields unfortunately are not localized on the brane.The following article appeared in AIP Conference Precedings, Vol. 1617, pp. 96-99 and may be found at http://dx.doi.org/10.1063/1.4897113.

Color of other individuals shown in Figs. 3&ndash;7. Figs. 6 and 7 extend the range to the island of Utila, Islas de Bah&iacute;a, Honduras. We also have a paratype collected at Utila by Benjamin B. Victor.&lt;/p&gt; &lt;p&gt; &lt;b&gt;Etymology:&lt;/b&gt; We are pleased to name this species for Patrick L. Colin, in recognition of his exceptional doctoral thesis on the comparative biology of western Atlantic gobies of the genus &lt;i&gt;Elacatinus&lt;/i&gt;, and for his help in our research on the genus.&lt;/p&gt; &lt;p&gt; &lt;b&gt;Remarks:&lt;/b&gt; We examined the holotype of &lt;i&gt;Elacatinus xanthiprora&lt;/i&gt; (ANSP 110898, 28.8 mm) from 23 m at Alligator Reef in the Florida Keys and the two paratypes from Dry Tortugas collected by W.H. Longley (USNM 118105, 22.9&ndash;25.6 mm), first identified by Longley in Longley &amp; Hildebrand (1941: 227) as &lt;i&gt;Elacatinus horsti&lt;/i&gt; (Metzelaar). The fourth paratype of &lt;i&gt;E. xanthiprora&lt;/i&gt; from Jamaica, collected by the first author from 24 m in 1959, is reidentified here as a new species that is described below, along with three specimens from the Serranilla Bank.&lt;/p&gt; &lt;p&gt; Two additional specimens of &lt;i&gt;Elacatinus xanthiprora&lt;/i&gt; were examined, one collected by Patrick L. Colin at Dry Tortugas in 13.5 m, in 1973 (UF 230715, 22.2 mm) (Fig. 8), and the other from trawl station 50 of the R/ V &lt;i&gt;Albatross IV&lt;/i&gt; in 26 m off the west coast of Florida, commencing at 28&deg;40&rsquo;54&rdquo;N, 83&deg;45&rsquo;18&rdquo;W in 1980 (ANSP 148926, 43.1 mm).&lt;/p&gt; &lt;p&gt; An underwater color photograph of &lt;i&gt;E. xanthiprora&lt;/i&gt; taken by Paul Humann off Key Biscayne, Miami (Humann, 2002: 265) was provided for this study (Fig. 9). It is the northernmost record of the species for the Atlantic coast of Florida.&lt;/p&gt; &lt;p&gt; We present the fin-ray counts of the six available specimens of &lt;i&gt;Elacatinus xanthiprora&lt;/i&gt; (all from Florida) in Table 1, along with those of &lt;i&gt;E. colini&lt;/i&gt; (types and nontypes). The pectoral-ray counts of 19 and 20 for &lt;i&gt;E. xanthiprora&lt;/i&gt; provide complete separation from &lt;i&gt;E. colini&lt;/i&gt;.&lt;/p&gt; &lt;p&gt; Comparison of the proportional measurements of &lt;i&gt;E. colini&lt;/i&gt; (Table 2) with those of &lt;i&gt;E. xanthiprora&lt;/i&gt; (Table 3) offers little to separate the species. The only nonoverlapping measurements are the snout length (shorter in &lt;i&gt;E. colini&lt;/i&gt;) and the length of base of dorsal fins (longer in &lt;i&gt;E. colini&lt;/i&gt;).&lt;/p&gt; &lt;p&gt; Most of the specimens of &lt;i&gt;E. colini&lt;/i&gt; have been collected in Pelican Cays of the lagoon area of the Belize Barrier Reef. We have not seen the species on the seaward side of the Mesoamerican Barrier Reef, or on the offshore reefs of Glovers and Lighthouse Atolls.&lt;/p&gt; &lt;p&gt; Tyler &amp; B&ouml;hlke (1972: 619) regarded &lt;i&gt;Elacatinus xanthiprora&lt;/i&gt; and relatives as facultative sponge dwellers, defined as species that spend at least a portion of their lives in or on tubular sponges. &lt;i&gt;E. colini&lt;/i&gt; clearly falls in this category. It has been observed in association with sixteen different sponges and often seeks refuge in the lumen of its hosts. In addition to the five sponges identified in our Figs. 3&ndash;7, we have seen &lt;i&gt;E. colini&lt;/i&gt; on or within &lt;i&gt;Aplysina fulva&lt;/i&gt;, &lt;i&gt;Aplysina&lt;/i&gt; sp. 1, &lt;i&gt;Aplysina&lt;/i&gt; sp. 2., &lt;i&gt;Ircinia&lt;/i&gt; sp., &lt;i&gt;Niphrates digitalis&lt;/i&gt;, &lt;i&gt;Spirastrella coccinea&lt;/i&gt;, &lt;i&gt;Verongula&lt;/i&gt; sp., and four unidentified sponge species. However, it has also been observed at rest on live coral (Fig. 2), and may hide in cracks in the reef when threatened. The two individuals of Fig. 4 were observed to retire to the sponge for the night.&lt;/p&gt; &lt;p&gt; &lt;b&gt;TABLE 3.&lt;/b&gt; Proportional measurements of type specimens of &lt;i&gt;Elacatinus xanthiprora&lt;/i&gt; as percentages of standard length. Holotype Nontype Paratype Nontype ANSP 110898 UF 230715 USNM 118105 ANSP 148926 Measurements were not taken from the two smallest paratypes due to their poor condition.&lt;/p&gt; &lt;p&gt; &lt;i&gt;Elacatinus colini&lt;/i&gt; has been found in the depth range of 2&ndash;17 m, but it probably occurs at greater depths. The coral reefs of the Pelican Cays area extend on sloping bottom to only about 18 m. This sponge goby is usually seen in pairs or small groups. It is sympatric with a blue-striped cleaning goby that has long been identified as &lt;i&gt;Elacatinus oceanops&lt;/i&gt; Jordan. However, the latter is another undescribed species of the genus (Randall &amp; Colin, MS). A third species of &lt;i&gt;Elacatinus&lt;/i&gt;, &lt;i&gt;E. lori&lt;/i&gt; Colin (Fig. 10), also a sponge inquiline, was described from Belize, but is known only from the seaward part of the barrier reef. Colin (1975: 98-99) had tentatively identified this species as the white form of &lt;i&gt;E. horsti&lt;/i&gt; (Metzelaar). We present an illustration of the true &lt;i&gt;E. horsti&lt;/i&gt; as Fig. 11.&lt;/p&gt; &lt;p&gt; &lt;i&gt;Elacatinus randalli&lt;/i&gt; is similar in color to &lt;i&gt;E. colini&lt;/i&gt; and &lt;i&gt;E. xanthiprora&lt;/i&gt;, especially in the snout coloration, and it may be found on sponge as in Fig. 12, but it is a cleaner goby.&lt;/p&gt; &lt;p&gt; &lt;i&gt;Elacatinus colini&lt;/i&gt; has a thick coat of mucus over the head, body, and fins. The mucus congeals in formalin-preserved specimens to a tough, faintly translucent, whitish coating that nearly obliterates the black markings. The first specimen collected for this study was damaged in the attempt to remove the mucus, and no measurements were taken from it for Table 2.&lt;/p&gt; &lt;p&gt; Smith &amp; Tyler (1972: 160) reported that the mucus of the sponge-dwelling &lt;i&gt;Elacatinus chancei&lt;/i&gt; (Beebe &amp; Hollister) contains a repelling substance after they observed the hamlet &lt;i&gt;Hypoplectrus puella&lt;/i&gt; (Cuvier) forcefully reject an individual of this goby, following its initial seizure. Colin (1975: 243&ndash;247) discussed experiments demonstrating the noxious quality of the skin of &lt;i&gt;E. horsti&lt;/i&gt; and &lt;i&gt;E. chancei&lt;/i&gt;.&lt;/p&gt; &lt;p&gt; The first author determined the suspected presence of a crinotoxin in the mucus of some species of grammistine, gobiesocid, and callionymid fishes by the bitter taste of the mucus. At his suggestion, the second author and students tasted the mucus of &lt;i&gt;E. colini&lt;/i&gt; and found it very bitter and somewhat peppery. The mucus of the sympatric cleaning goby also tasted bitter, but not so strongly. One could assume that the latter would not need as much chemical protection because of its symbiotic association with numerous species of Caribbean reef fishes.&lt;/p&gt; &lt;p&gt; Although these two species of &lt;i&gt;Elacatinus&lt;/i&gt; on lagoon reefs of Belize are readily separated by the color of the stripe on the upper side of the body in life, white in &lt;i&gt;E. colini&lt;/i&gt; and blue in the undescribed cleaner goby, a close examination is needed to distinguish them as preserved specimens. The overhanging snout and ventral mouth of the cleaning goby provides the most obvious difference. Other morphological differences are its shorter pelvic fins, 16.4&ndash;17.6% SL, compared to 23.3&ndash;25.3% SL of &lt;i&gt;E. colini&lt;/i&gt;, and the rounder pelvic disk, reflecting its use as a strong sucking disk when it attaches to the host fishes. There is also a difference in the ventrolateral black stripe. It is broader on the cleaning goby and extends onto the side of the snout.&lt;/p&gt; &lt;p&gt; Because Colin (1975: 119) found the parasitic polychaete &lt;i&gt;Haplosyllis spongicola&lt;/i&gt; as the principal component of the gut contents of the four species of sponge-dwelling &lt;i&gt;Elacatinus&lt;/i&gt; that he was able to dissect, &lt;i&gt;E. chancei&lt;/i&gt;, &lt;i&gt;E. horsti&lt;/i&gt;, &lt;i&gt;E. louisae&lt;/i&gt;, and &lt;i&gt;E. tenox&lt;/i&gt;, we expected to find the polychaete in the digestive tract of &lt;i&gt;E. colini&lt;/i&gt;. However, the seven adult type specimens that we dissected were largely empty, and none contained anything that we could identify as polychaete. One fish had eaten copepods, which might be anticipated because individuals on the reef occasionally make quick upward forays, as if to feed on zooplankton. Another fish contained only one small larval gnathiid isopod and a tiny fish scale. This supports the fleeting observation by the second author of what appeared to be a brief cleaning of a reef fish by &lt;i&gt;E. colini&lt;/i&gt;. Three nontype specimens from Belize were obtained from David G. Smith of the National Museum of Natural History for further dissection. All had empty digestive tracts. Although additional specimens may yet reveal feeding on the parasitic polychaete, our limited data suggest that it is not a major food source.&lt;/p&gt; &lt;p&gt; An abundance of polychaete remains were found in two specimens of the undescribed species of spongedwelling &lt;i&gt;Elacatinus&lt;/i&gt; from Isla de Providencia. The gut material was sent to Leslie H. Harris of the Natural History Museum of Los Angeles County, who confirmed it as belonging to the genus &lt;i&gt;Haplosyllis&lt;/i&gt;.&lt;/p&gt; &lt;p&gt; We contacted two aquarium fish collectors in Florida with a request to provide tissue samples of specimens of &lt;i&gt;Elacatinus xanthiprora&lt;/i&gt; so that genetric comparison could be made with our tissue samples of &lt;i&gt;E. colini&lt;/i&gt;. Both collectors know the species but indicated that they rarely catch it because of its occurrence on deep reefs.&lt;/p&gt;Published as part of &lt;i&gt;Randall, John E. &amp; Lobel, Phiillip S., 2009, A literature review of the sponge-dwelling gobiid fishes of the genus Elacatinus from the western Atlantic, with description of two new Caribbean species, pp. 1-19 in Zootaxa 2133&lt;/i&gt; on pages 5-11, DOI: &lt;a href="http://zenodo.org/record/274944"&gt;10.5281/zenodo.274944&lt;/a&gt
