Therasia tamora Hutton 1883
No full textTherasia tamora Hutton, 1883 Pl. 4, fig. E Hutton, 1883. The New Zealand Journal of Science, 1: 477. Type material. Lectotype (designated by Cumber 1967: 69), CMNZ M10283 [ex M260], and paralectotypes (3), CMNZ M260 (dry shells). CMNZ molluscan catalogue details. M260—‘ Therasia tamora Hutton, Auckland (4 specimens) (old No. 48) ’. Type locality. ‘ Auckland (T. F. Cheeseman)’ (Hutton 1883g: 477, Hutton 1884b: 182). Previous illustrations of type material. Pilsbry (1892 [in 1892–1893]: 70, 303, pl. 22, figs. 49–51—‘from the type’, ‘H. Suter, del.’); Suter (1915: pl. 9, figs. 7, a, b—possibly the same shell as illustrated by Pilsbry); Cumber (1961: fig. 2 D–F). Remarks. Hutton submitted a description of this species to the Transactions and Proceedings of the New Zealand Institute issue for 1883, but publication was delayed until May 1884 (Hutton 1884b: 182), and was preempted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1883g: 477). Powell (1948: 276) erected the genus Therasiella for T. tamora and two other species, noting that they differed from typical Therasia in having membranously plaited epidermal processes, and a smaller number of teeth in the radula. In a taxonomic review of Therasiella, Cumber (1967: 69) noted that tamora differed from other species in this genus in having “oblong, bluntly rounded extensions of the periostracal plaits together with the absence of any fine processes on these plaits”. These periostracal processes are commonly damaged or lost during life or subsequent preservation of shells, and although depicted in illustrations by Pilsbry (1892 [in 1892–1893]: pl. 22, figs. 49–51) and Suter (1915: pl. 9, figs. 7, a, b), they are absent from the three extant type specimens of T. tamora. Current taxonomy. Therasiella tamora (Hutton, 1883) — Powell (1948: 276, 1957: 118, 1979: 312), Cumber (1967: 67), Spencer et al. (2009: 216). Distribution. New Zealand; northern North Island and nearshore islands from Houhora south to Kawhia and Gisborne, and on Marotere/Chicken, Taranga/Hen and Hauturu/Little Barrier islands (Suter 1913: 660; Cumber 1967: 69, fig. 5E; Powell 1979: 312; AIM and NMNZ collection records).Published as part of Brook, Fred J., Kennedy, Martyn, King, Tania M., Ridden, Johnathon, Shaw, Matthew D. & Spencer, Hamish G., 2020, Catalogue of New Zealand land, freshwater and estuarine molluscan taxa named by Frederick Wollaston Hutton between 1879 and 1904, pp. 1-73 in Zootaxa 4865 (1) on pages 35-37, DOI: 10.11646/zootaxa.4865.1.1, http://zenodo.org/record/442842
Charopa miranda Hutton 1883
No full textCharopa miranda Hutton, 1883 Pl. 3, fig. F Hutton, 1883. New Zealand Journal of Science, 1: 476. Type material. Lectotype (designated by Marshall & Barker 2008: 145), CMNZ M12780 [ex M239], and paralectotypes, CMNZ M239 (1), CMNZ M12785 [ex M239] (4) (dry shells). Paralectotypes in CMNZ M12785 are Granallodiscus mayhillae Marshall & Barker, 2008, according to Marshall & Barker (2008: 145). The molluscan collection at CMNZ has radula fragments mounted on a glass slide with the label details ‘ Psyra miranda, Greymouth, XVI p. 180’, in Hutton’s handwriting (i.e., CMNZ 2017.17.70), which is probably primary type material (see descriptions of radula and jaw by Hutton 1884b: 181). Label details. CMNZ M239—‘59. Psyra miranda Hutton, Greymouth’, pillbox label in Hutton’s handwriting. Type locality. ‘Greymouth (R. Helms)’ (Hutton 1883g: 476, 1884b: 181). Previous illustrations of type material. Jaw and radula teeth illustrated by Hutton (1884b: pl. 9, fig. W, pl. 11, fig. S) probably from type material; Pilsbry (1892 [in 1892–1893]: 68, 303, pl. 22, figs. 40–42—‘drawn from Prof. Hutton’s type’, ‘H. Suter, del.’); Suter (1915: pl. 9, figs. 3, a, b—possibly type material). Remarks. Hutton submitted a description of this species to the Transactions and Proceedings of the New Zealand Institute issue for 1883, but publication was delayed until May 1884 (Hutton 1884b: 180), and was preempted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1883g: 476). There has been confusion over the identity and distribution of Charopa miranda Hutton, 1883, as indicated in synonymies by Marshall & Barker (2008). In order to stabilize the nomenclature the last-mentioned authors designated a lectotype of miranda (CMNZ M12780), illustrated here in pl. 3 fig. F, which they also designated as a neotype of Helix granum Pfeiffer, 1857, thus making Charopa miranda Hutton, 1883 a junior synonym of the latter taxon. According to Marshall & Barker (2008: 146, fig. 33B), this species has a wide distribution in the southeastern North Island and northern South Island. Current taxonomy. An objective junior synonym of Granallodiscus granum (Pfeiffer, 1857) — Marshall & Barker (2008: 145).Published as part of Brook, Fred J., Kennedy, Martyn, King, Tania M., Ridden, Johnathon, Shaw, Matthew D. & Spencer, Hamish G., 2020, Catalogue of New Zealand land, freshwater and estuarine molluscan taxa named by Frederick Wollaston Hutton between 1879 and 1904, pp. 1-73 in Zootaxa 4865 (1) on pages 30-32, DOI: 10.11646/zootaxa.4865.1.1, http://zenodo.org/record/442842

Sertularella simplex Hutton 1873
No full textSertularella simplex (Hutton, 1873) Synonyms in the area:? Sertularella ellisii f. lagenoides —Leloup 1974 p. 28 [polyp]; Sertularella peregrina —Leloup 1974 p. 31–32 [polyp]. Remarks: Galea & Schories (2012a p. 46) considered that “Leloup’s (1974) material assigned to both S. ellisi f. lagenoides and S. peregrina may belong to either this species [Sertularella sp.] or S. mixta, since no measurements allowing a reliable comparison were provided by this author”. Moreover, Sertularella peregrina Bale, 1926 is considered a synonym of Sertularia simplex in WoRMS (Schuchert 2016). Given the uncertainties about these records, we conservatively include them in the synonym of S. simplex, pending more detailed study. Distribution in South America: polyp—Pacific Ocean, Chile, at north of Coquimbo and in Puerto Melinka, Guaitecas Archipelago (Leloup 1974 p. 28, 31–32).

Amphidoxa costulata Hutton 1882
No full textAmphidoxa costulata Hutton, 1882 Pl. 2, fig. E Hutton, 1882. New Zealand Journal of Science, 1: 281. Type material. Lectotype (designated by Climo 1970: 335), CMNZ M12778 [ex M294], and paralectotypes (2), CMNZ M294 (dry shells). The molluscan collection at CMNZ has radula fragments mounted on a glass slide with the label details ‘ Calymna costulata, Auckland, XVI p. 171’, in Hutton’s handwriting (i.e., CMNZ 2017.17.11), which is probably primary type material (see radula description by Hutton 1883d: 136). Label details. CMNZ M294—‘38. Calymna costulata Hutton, Auckland’, pillbox label in Hutton’s handwriting. Type locality. ‘ Auckland (T. F. Cheeseman)’ Hutton (1882p: 281, 1883d: 136). Previous illustrations of type material. Radula teeth illustrated by Hutton (1884b: pl. 10, fig. D) probably from type material; Pilsbry (1893 [in 1893–1895]: 346, pl. 3, figs. 20–22—‘ Type. Suter, del.’); Suter (1915: pl. 26, figs. 15, a, b—possibly type material). Remarks. Hutton submitted a description of this species to the Transactions and Proceedings of the New Zealand Institute issue for 1882, but publication was delayed until May 1883 (Hutton 1883d: 136), and was preempted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1882p: 281). A description by Hutton (1884b: 171) of a radula of costulata was probably based on the putative type material in CMNZ 2017.17.11 mentioned above. Amphidoxa costulata Hutton, 1882 is the type species of Calymna Hutton, 1883, by original designation, and of Flammocharopa Climo, 1970, also by original designation. As noted in the section on Hutton’s genus group names (above), Calymna Hutton, 1883 has been incorrectly interpreted as a homonym of Calymma Hübner, (1816–1826) 1823 [Lepidoptera] by Pilsbry (1893 [in 1893–1895]: 17), Suter (1913: 671), Thiele (1931 [1929–1935]: 575), Zilch (1959 [in 1959–1960]: 222) and Schileyko (2001: 1025), based on a subsequent misspelling of the latter name as ‘ Calymna Hübner’ by Walker (1858: 13). Flammocharopa Climo, 1970 has the same type species as Calymna Hutton, and is a junior synonym. Taxonomy. Calymna costulata (Hutton, 1882) —after Hutton (1883i: 532, 1884c: 199), Pilsbry (1893 [in 1893– 1895]: 346), Hedley & Suter (1893: 645), Suter (1894b: 241). Distribution. New Zealand; North Island, currently interpreted as being widely distributed from Northland to Wairarapa (e.g., Suter 1913: 676, Climo 1970: 335, Powell 1979: 308), but examination of material in the AIM and NMNZ collections indicates that this refers to a species complex, and the identity and distribution of Hutton’s species need to be re-evaluated.Published as part of Brook, Fred J., Kennedy, Martyn, King, Tania M., Ridden, Johnathon, Shaw, Matthew D. & Spencer, Hamish G., 2020, Catalogue of New Zealand land, freshwater and estuarine molluscan taxa named by Frederick Wollaston Hutton between 1879 and 1904, pp. 1-73 in Zootaxa 4865 (1) on page 24, DOI: 10.11646/zootaxa.4865.1.1, http://zenodo.org/record/442842
Leptopoma calva Hutton 1882
No full textLeptopoma calva Hutton, 1882 Pl. 1, fig. C Hutton, 1882. New Zealand Journal of Science, 1: 282. Type material. Single shell formerly in the collection at Canterbury Museum, Christchurch (Hutton 1898 – 1900: 5; Suter 1913: 179) but reported missing by Freeman et al. (1997: 36), and not found subsequently. Neotype selected by Marshall & Barker (2007: 60 — NMNZ M.174790). Type locality. listed as ‘Greymouth (R. Helms)’ by Hutton (1882p: 282, 1883d: 140); neotype from ‘South Island, N of Arthur’s Pass, Jacksons, near roadside on Otira–Kumara highway, 200 m (NZMS 260, K33/870283)’ (Marshall & Barker 2007: 60). Previous illustrations of type material. Suter (1915: pl. 35, fig. 1), Marshall & Barker (2007: fig. 4C). Remarks. Hutton submitted a description of this species to the Transactions and Proceedings of the New Zealand Institute issue for 1882, but publication was delayed until May 1883 (Hutton 1883d: 140), and was preempted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1882p: 282). A re-description and illustration of Leptopoma calva by Suter (1913: 179, pl. 35, fig. 1) was based on the type material from Canterbury Museum. Suter (1913: 179) and Dell (1955: 1136) stated that this species was known from the type specimen only. The latter author noted that Suter’s (1913) “description and figure are not highly diagnostic. Unfortunately the type cannot at present be located in the Canterbury Museum, and no topotypes appear to have been collected”. Dell (1955: 1136) identified material of “a moderately common shell in Fiordland” as Murdochia cf. calvum (Hutton), but noted that “until these shells can be critically compared with undoubted specimens of calvum, the identification cannot be certain”. Marshall & Baker (2007) redescribed Leptopoma calva Hutton, 1882 as part of a taxonomic review of Cytora Kobelt & Möllendorff, 1897, noting that the shell of this species is distinctive in having a maculate colour pattern, although the latter feature was not mentioned in the descriptions by Hutton (1882p, 1883d) or Suter (1913), and they identified ‘ Murdochia cf. calvum ’ of Dell (1955) as Cytora mayhillae Marshall & Barker, 2007. Marshall & Barker (2007: 60) selected a neotype of calva, NMNZ M. 174790 (pl. 1, fig. C), that “represents the only Cytora species occurring in the vicinity of Greymouth that is accordant with Hutton’s descriptions and Suter’s (1913) crude illustration of the holotype ”. This in itself is not sufficient justification for the designation of a neotype under ICZN Art. 75.3 but, given that previously there had been confusion over the identity of calva, we agree that a neotype was required to stabilise the nomenclature. The neotype selected by Marshall & Barker (2007: 60) was from the Otira-Kumara Highway, c. 45 km SE of Greymouth; they stated that they had “not seen any reliably localised specimens from Greymouth or the immediate vicinity of that town, so we have chosen the neotype from one of the nearest localities where the species is definitely known to occur”. Subsequently, C. calva has been found living in Omotumotu Bush, Greymouth, and on Peter Ridge, and near Point Elizabeth, on the southern and northern outskirts of the town, respectively (F. Brook pers. obs.). Current taxonomy. Cytora calva (Hutton, 1882) — Powell (1957: 90), Powell (1979: 85), Marshall (1995: 496), Marshall & Barker (2007: 60), Spencer et al., (2009: 203). Distribution. New Zealand; northwestern South Island, from Granity and Nelson Lakes southwest to Lake Kaniere (Marshall & Barker, 2007: fig. 8A; NMNZ collection records).Published as part of Brook, Fred J., Kennedy, Martyn, King, Tania M., Ridden, Johnathon, Shaw, Matthew D. & Spencer, Hamish G., 2020, Catalogue of New Zealand land, freshwater and estuarine molluscan taxa named by Frederick Wollaston Hutton between 1879 and 1904, pp. 1-73 in Zootaxa 4865 (1) on pages 12-13, DOI: 10.11646/zootaxa.4865.1.1, http://zenodo.org/record/442842

Charopa planulata Hutton 1883

Lectotype (designated by Climo & Mahlfeld 1998: 2), CMNZ M12773 [ex M1039], and paralectotypes (2), CMNZ M1039 [ex ZS 671] (dry shells). Label details. CMNZ M1039—‘ Auckland, T.F.

Previous illustrations of type material. Radula teeth illustrated by Hutton (1884b: pl. 9, fig. J) probably from type material; Climo & Mahlfeld (1998: fig. 1A—lectotype). Remarks. Hutton submitted a description of this species to the Transactions and Proceedings of the New Zealand Institute issue for 1883, but publication was delayed until May 1884 (Hutton 1884b: 181), and was preempted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1883g: 477). There has been considerable confusion over the identity and distribution of Charopa planulata, as indicated by synonymies of Climo & Mahlfeld (1998) and Marshall & Barker (2008: 83, 85, 115, 116). Following misidentifications by Pilsbry (1892 [in 1892–1893]: 67; 1893 [in 1893–1895]: pl. 3, figs. 4–6), planulata was generally assigned to Allodiscus Pilsbry, 1892 at subgenus or genus level, and Hutton’s species name was misapplied to several different taxa, and interpreted as having a wide distribution in New Zealand (e.g., Suter 1913; Powell 1979). Climo & Mahlfeld (1998) stated that all previous records of planulata except the type material were of other species, and they reassigned Charopa planulata Hutton, 1883 to genus Chaureopa Climo, 1985. Charopa planulata Hutton, 1883 is possibly conspecific with Chaureopa microumbilicata Climo, 1985. Type material of the former taxon has a shell of up to 2.7 mm diameter at 4.0 whorls, with a slightly elevated spire, an almost closed umbilicus, teleoconch sculpture of crisp, closely-spaced, sigmoidal radial ribs, and a smooth, glossy protoconch of 1.3–1.4 whorls and maximum diameter of 0.53–0.60 mm. Chaureopa microumbilicata, with a holotype from Kauaeranga Valley, Thames, attains a slightly larger size than the type material of planulata (max. diameter of 3.15 mm at 4.6 whorls), but has similar shell shape and teleoconch sculpture. Shells of microumbilicata generally have a narrowly open umbilicus c. 8–13% of maximum shell diameter (e.g., AIM MA84935, MA96690, NMNZ M.62443, M.62444, M.78793, M.97634, M.186395, M.186508, M.301462), but some populations in Hunua Ranges and Thames, southeast of Auckland, contain shells that have the umbilicus almost closed, as in the type material of planulata (e.g., AIM MA84932, MA97021, NMNZ M.78794). Protoconch size in microumbilcata is also variable, ranging from 0.54–0.74 mm in maximum diameter, and 1.3–1.7 whorls. The two taxa have overlapping distributions: planulata was described from material collected in Auckland; microumbilicata has a sparse distribution in the northeastern North Island between Waiwera, north of Auckland, and Bay of Plenty (AIM and NMNZ collection records). Current taxonomy. Chaureopa planulata (Hutton, 1883) — Climo & Mahlfeld (1998: 1), Spencer et al. (2009: 215). Distribution. New Zealand; North Island, recorded from Auckland only by Climo & Mahlfeld (1998), but if synonymous with Chaureopa microumbilicata Climo, 1985 it has a wider, albeit sparse, distribution in the northeastern North Island, between Waiwera and Bay of Plenty.Published as part of Brook, Fred J., Kennedy, Martyn, King, Tania M., Ridden, Johnathon, Shaw, Matthew D. & Spencer, Hamish G., 2020, Catalogue of New Zealand land, freshwater and estuarine molluscan taxa named by Frederick Wollaston Hutton between 1879 and 1904, pp. 1-73 in Zootaxa 4865 (1) on pages 33-34, DOI: 10.11646/zootaxa.4865.1.1, http://zenodo.org/record/442842
Rhytida patula Hutton, Greymouth 1882
No full textRhytida patula Hutton, 1882 Pl. 6, figs. E, F Hutton, 1882. The New Zealand Journal of Science, 1: 282. Type material. Lectotype (designated by Powell 1946: 127), CMNZ M122 [ex ZS 823], and paralectotypes (5), CMNZ M121 (dry shells). The molluscan collection at CMNZ has a radula mounted on a glass slide with the label details ‘ Rhytida patula, Greymouth, XVI p. 167’, in Hutton’s handwriting (i.e., CMNZ 2017.17.59), which is probably primary type material (see radula descriptions by Hutton 1883d: 139, 1884b: 167). Label details. CMNZ M121 —‘ Greymouth, Hutton coll.’, CMNZ M122 —‘ Greymouth, R. Helms coll.’, ‘ Lectotype sel. by A.W. B. Powell 1936 ’, and accompanying handwritten note ‘ Largest is holotype, agrees with Hutton’s dimensions. AWBP’. CMNZ molluscan catalogue details. M121—‘ Rhytida patula Hutton, Greymouth, (old No., 121)’; M122— ‘ Rhytida patula Hutton, Greymouth, presumably Type, (ZS 823)’. Type locality. ‘Greymouth (R. Helms)’ (Hutton 1882p: 282, 1883d: 139). Previous illustrations of type material. Radula teeth illustrated by Hutton (1884b: pl. 10, fig. Q) probably from type material; Powell (1946: text figs. D4–6— lectotype). Remarks. Hutton submitted a description of Rhytida patula to the Transactions and Proceedings of the New Zealand Institute issue for 1882, but publication was delayed until May 1883 (Hutton 1883d: 139), and was preempted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1882p: 282). A description by Hutton (1884b: 167, pl. 10, fig. Q) of a radula of patula was probably based on the putative type material in CMNZ 2017.17.59 mentioned above. As noted in the preceding species entry, Hutton (1883d: 139) differentiated R. patula from R. citrina, both described from material from Greymouth, on the basis of shell and animal coloration, and radula details. From the start there has been confusion over the identity and distribution of both species. Powell (1946: 127) noted that type material of R. patula at CMNZ comprised six ‘co-types’ and he selected the largest specimen, which most closely matched the shell dimensions given by Hutton (1883d: 138), as the lectotype, which is illustrated here in pl. 6, fig. F. Re-examination of this type series indicates that it is a mixed lot that contains two different species, a fact evidently not recognized by Hutton and other workers. One paralectotype (M121.5) is conspecific with the lectotype of R. patula, three match the neotype of R. citrina Hutton, 1882 and are interpreted here as that species (M121.1–M121.3), and one small juvenile shell was indeterminate (M121.4). One of the paralectotypes identified as R. citrina, M121.3, is illustrated here in pl. 6, fig. E. Records of R. patula from Balclutha by Hutton (1884b: 167, 1884c: 208), Hedley & Suter, (1893: 630) and Suter (1894b: 286, 1913: 777), based on CMNZ M1417, refer to a different species, Rhytida otagoensis Powell, 1930. Powell (1946: 127, 1979: 345) recorded R. patula from several localities on the West Coast of the South Island between Whanganui Inlet and Lake Kaniere, and Parkinson (1979: 10) stated that this species was distributed over “most of the West Nelson block”. Efford (1998: 36, fig. 4J) mapped R. patula as having a wide distribution in the northwestern South Island, from Cape Farewell south to Shantytown (south of Greymouth) and Lewis Pass, albeit noting that this could be a complex of related species. Preliminary results of a phylogenetic study (M. Kennedy & T. King unpub. data) confirm this suspicion, and indicate that R. patula has a more restricted distribution than previously recognised (see below). Assigned to genus Rhytida Albers, 1860 by Hutton (1882) and subsequent authors, but this placement requires re-evaluation (M. Kennedy & T. King unpub. data). Current taxonomy. Rhytida patula Hutton, 1882 — Hutton (1884b: 167, 1884c: 208), Hedley & Suter (1893: 630), Suter (1894b: 286, 1913: 776), Powell (1946: 127, 1979: 345), Parkinson (1979: 10), Efford (1998: 36), Spencer et al. (2009: 218). Distribution. New Zealand; northern West Coast, coastal ranges between Charleston and Shantytown (AIM and NMNZ collection records).
