Phacussa helmsi var. maculata Hutton, 1884 View in CoL

Pl. 3, fig. A

Hutton, 1884. Transactions of the New Zealand Institute, 16 (1883): 205.

Type material. Syntypes (6), CMNZ M253 View Materials (dry shells). The molluscan collection at CMNZ has radula fragments mounted on a glass slide with the label details ‘ Phacussa maculata, Greymouth, XVI p. 172’, in Hutton’s handwriting (i.e., CMNZ 2017.17.115), which is probably primary type material.

Label details. CMNZ M253—‘43. Phacussa helmsii var. maculata Hutton , Greymouth’, pillbox label in Hutton’s handwriting.

Type locality. ‘Greymouth (Helms)’ ( Hutton 1884c: 205).

Remarks. The type material of Phacussa helmsi var. maculata Hutton, 1883 was reported as missing by Freeman et al. (1997: 36) but has since been found. A shell from the type series is illustrated here for the first time in pl. 3, fig. A. Phacussa helmsi var. maculata Hutton, 1883 was described from material from the same locality as Phacussa helmsi (Hutton, 1882) , and is a colour form of the latter taxon that does not warrant separate taxonomic status.

Current taxonomy. A subjective junior synonym of Phacussa helmsi (Hutton, 1882) — Suter (1913: 624).
