B. test4 ovato-conici, griseo-cinered, acuta, longitudinaliter plicata, 
transversim striata; ultimo anfractu. convexiore; apertura ovata, viola- 
cea; labro dextro intus striato. 
Shell ovate, conical, of an ash-gray color; spire pointed, 
composed of six or seven whirls, the lowest of which com- 
poses alone nearly half of the shell; this is swollen, and 
slightly compressed above. ‘The other whirls are somewhat 
convex, except the last but one; their surface is ornamented 
with eleven or twelve distant, prominent, rounded, longitudinal 
folds, intersected transversely by fine compact strie. Aper- 
ture ovate, slightly oblique, of a violet gray ; right lip furnished 
interiorly with numerous strie which are continued even to 
the depth of the cavity. Columella smooth and whitish, with 
a pretty prominent fold at the base. 
Length 1 inch. Width 6 lines. 
Inhabits the Isle of New Ireland. 
We refer to this species, a shell described and figured by 
Quoy and Gaimard under the name of Purpura nassotdes. 
Voyage de l Astrolabe, page 564, pl. 38, fig. 10-10. 
The specimen which was made use of by those naturalists, 
appears to us to be the same shell, only smaller, and in a less 
perfect state of preservation; for it presents precisely the same 
characters as that of which we have just given a description.
