Hutton, 1882. The New Zealand Journal of Science, 1: 281.
Type material. Lectotype (designated here), CMNZ M1382.1, and paralectotypes, CMNZ M1382.2 (1), NMNZ M.276340 [ex H. Suter colln.] (3) (dry shells). The molluscan collection at CMNZ has radula fragments mounted on a glass slide with the label details ‘ Phrixgnathus marginatus, Greymouth, XVI p. 168’, in Hutton’s handwriting (i.e., CMNZ 2017.17.7), which is probably primary type material (see radula descriptions by Hutton 1883d: 137, 1884b: 168).
Label details. CMNZ M1382—‘Greymouth, R. Helms, Hutton Coll. pill box no. 111’; NMNZ M.276340— ‘81. Phrixgnathus marginatus, Hutt., Helms, Greymouth’, in H. Suter’s handwriting.
CMNZ molluscan catalogue details. M1382—‘ Phrixgnathus marginatus Hutton, Greymouth (2 specimens) (old No. 111) ’.
Type locality. ‘Greymouth (R. Helms)’ (Hutton 1882p: 281, 1883d: 137).
Previous illustrations of type material. Radula teeth illustrated by Hutton (1884b: pl. 9, fig. S) probably from type material; Pilsbry (1892 [in 1892–1893]: 60, 304, pl. 23, figs. 94–96—‘drawn from the type’, ‘H. Suter, del.’); Suter (1915: pl. 10, figs. 4, a, b).
Remarks. Hutton submitted a description of Phrixgnathus marginatus to the Transactions and Proceedings of the New Zealand Institute issue for 1882, but publication was delayed until May 1883 (Hutton 1883d: 137), and was pre-empted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1882p: 281). A description by Hutton (1884b: 168, pl. 9, fig. S) of a radula of marginatus was probably based on the putative type material in CMNZ 2017.17.7 mentioned above. This species was recorded from Greymouth only by Hutton (1884c: 197), Hedley & Suter (1893: 647), Suter (1894b: 278, 1913: 754) and Powell (1979: 329), but museum collection records indicate that it is more widely distributed on the West Coast, South Island (below). Phrixgnathus marginatus Hutton, 1882 is the type species of Phrixgnathus Hutton, 1882, by monotypy (i.e., not P. celia Hutton, 1883, by subsequent designation, as incorrectly stated by Pilsbry 1893 [in 1893–1895]: 9; Suter 1913: 738; Powell 1979: 325; Schileyko 2002: 1048).
Current taxonomy. Phrixgnathus marginatus Hutton, 1882 — Hutton (1884c: 196), Spencer et al. 2009 (217).
Distribution. New Zealand; northwestern South Island, between Greymouth and Cape Farewell (AIM and NMNZ collection records).
