May 1849. Expedition Shells, 64. 
Animal of a clear, pale yellowish colour. Head small, short, and 
depressed, never apparently extended beyond the foot, which is elon- 
gated, oval posteriorly, and nearly square with a faint submarginal 
fissure in front. Tentacles rather long, slender and subulate, with 
the eyes on a very slight, lateral enlargement at their upper third. 
Siphon pale yellow, dotted white, rarely protruded beyond the canal. 
Operculum unguiculate, thin, horny, yellowish at margin, brown at 
apex, which is acute, somewhat lateral; strie of increment rather 
coarse, Somewhat imbricated. 
SxHevt fusiform-turreted, of an ashy colour. Volutions seven or 
eight, convex and slightly angular, longitudinally traversed by eight 
or nine prominent, subangular varices, and by as many as fourteen 
close, elevated strie#, with broader intervening sulci on the last volu- 
tion, which constitutes half the entire shell, and from three to five on 
the others. ‘These strie or cost are traversed by close and fine incre- 
mental striz, giving them an imbricated, and the sulci a reticulate 
aspect. Aperture oval, right lip slightly evasive and feebly furrowed 
within; columella arcuated superiorly, and inclining rather suddenly 
to the left, a short distance above the canal, which is short, straight, 
and feebly recurved: within polished, purplish. [3. p. c.]
