Gerontia pantherina Hutton, 1882 Pl. 3, fig. G Hutton, 1882. New Zealand Journal of Science, 1: 281. Type material. Lectotype (designated here), CMNZ M12781 [ex M244], and paralectotypes, CMNZ M244 (3), CMNZ M1037 [ex ZS 662] (3), NMNZ M.275967 [ex H. Suter colln.] (4) (dry shells). The molluscan collection at CMNZ has radula fragments mounted on a glass slide with the label details ‘ Gerontia pantherina, Greymouth, XVI p. 166’, in Hutton’s handwriting (i.e., CMNZ 2017.17.49), which is probably primary type material (see description of radula by Hutton 1883d: 135). Label details. CMNZ M244—‘39. Gerontia pantherina Hutton, Greymouth’, pillbox label in Hutton’s handwriting; NMNZ M.275967—‘94. Flammulina Gerontia pantherina, Hutt., Hel. [= R. Helms], Greymouth’, in H. Suter’s handwriting. CMNZ molluscan catalogue details. M1037—‘ Gerontia pantherina Hutton, Greymouth (old number ZS 662)’. Type locality. ‘Greymouth (R. Helms)’ (Hutton 1882p: 281, 1883d: 135). Previous illustrations of type material. Jaw and radula teeth illustrated by Hutton (1884b, pl. 9, fig. I, pl. 11, fig. R) and Pilsbry (1893 [in 1893–1895]: pl. 2, figs. 4, 5) probably from type material. Remarks. Hutton submitted a description of Gerontia pantherina to the Transactions and Proceedings of the New Zealand Institute issue for 1882, but publication was delayed until May 1883 (Hutton 1883d: 135), and was pre-empted by his brief description of Gerantia [sic] pantherina in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1882p: 281). Descriptions by Hutton (1884b: 166, pl. 9, fig. I, pl. 11, fig. R) of a jaw and radula of pantherina were probably based on the putative type material in CMNZ 2017.17.49 mentioned above. Gerontia pantherina is the type species of Gerontia Hutton, 1882, by monotypy. Current taxonomy. Gerontia pantherina Hutton, 1882 — Hutton (1883d: 135), Suter (1913: 634), Powell (1979: 312), Spencer et al. (2009: 215). Distribution. New Zealand; western South Island, predominantly in the northern part between Burnett Range and Ross, with scattered records south to Jackson Head (Suter 1913: 635; Powell 1979: 312; AIM and NMNZ collection records).
