Material examined

GALICIA BANK • 1 spm; 43°00.12′ N, 11°57.67′ W; 1706 m; 29 Jul. 2011; BANGAL 0711 V2; MNCN • 1 spm; 42°41.87′ N, 11°26.71′ W; 1720 m; 8 Aug. 2011; BANGAL 0711 V10; MNCN .

Remarks

This species was described on a single specimen, probably immature judging from the very thin, brittle aperture. The specimen illustrated here is larger and definitely adult, but has, like the holotype, a small mucronate protoconch, teleoconch whorls unusually convex for a eulimid, and a projecting profile of the outer lip, making this the closest match we could find among the species described from the area. This identification remains tentative, especially taking into account that the host holothurian species was not found in our material.
