Description

A deep-water form seems to possess the main sculptural elements of odhneri, hut differs in the smaller size, more numerous axials. and different outline. It is here described as a benthic representative of odhneri. Protoconch paucispiral, the first whorl small and rather flat, the second whorl sculptured with 3 strong spiral keels. Two major spirals on the shoulder. 1 between the major keels, and 3 below the major keel. Body whorl with 4 spaced major spirals and 4 fine spirals on the shoulder. 1 spiral between the uppermost pair of major spirals, the lower pairs with up to 3 narrow spirals between them. Four strong spirals on the base and a few narrower, rather indefinite, spirals on the fasciole. The spirals are crossed by axials, 15 in number on the spire whorls and 17 on the body whorl, those on the body whorl becoming obsolete across the base. The spire whorls are hardly keeled by the major spirals and the body whorl appears evenly convex, in contrast to odhneri, where the uppermost major spiral forms a distinct keel. In addition, the base is less rapidly constricted and the canal appears more open, Height, 5,7 mm.; diameter. 2,5 mm.
