robustum Heath, 1911; Chaetoderma

Chaetoderma robustum Heath, 1911: 43–44, 68–69; pl. 4, figs. 5, 19; pl. 30, figs. 2, 4–6, 10, 13; pl. 37, fig. 4.

Type locality. Sanak Island, Sanak Islands (54°0’0”N, 162°40’30’’W), South of Alaska Peninsula, USA, 483 fathoms (884 m) .

Type material. Syntype MCZ 362002 (two fragments of the same specimen) .

Remarks. Heath (1911) based his original description of C. robustum on four specimens from ‘Albatross’ station 3210 without designating a type. The labels accompanying MCZ 362002 incorrectly refer the two fragments as being from the ‘holotype’. Stasek (1966) recorded a set of slides in the California Academy of Sciences (CAS 21399; formerly CAS 196) with serial sections from one of four syntype specimens.
