Material examined
SOUTH AFRICA – Eastern Cape • 3 living specimens; off Mbashe River; stn Q1; 32°18.2′ S, 29°4.1′ E; depth 200–220 m; 18 Jul. 1982; Natal Museum Dredging Programme, R.V. Meiring Naudé leg.; sponge rubble; NMSA V908 .
WALTERS SHOAL – slopes • 1 empty shell; stn DW4893; 33°16′ S, 43°58′ E; depth 623–629 m; 4 May 2017; MNHM.
Distribution
Recorded from off northern New Zealand, 27–805 m (living, 88–221 m) (Marshall 1995) and the east coast of South Africa (200–220 m, living in sponge dominated communities) (Herbert 2015). Here recorded also from the slopes of Walters Shoal, at a depth of 623– 629 m.
Remarks
I have previously drawn attention to the occurrence of this genus in the south-western Indian Ocean (Herbert 2015). A single specimen belonging to the same species was obtained on Walters Shoal. I can find no features by which south-western Indian Ocean specimens can be convincingly distinguished from those from New Zealand and thus consider them to be conspecific.
