(Collect. Mass. Lam.) Guautiert, Test., pl. 44, fig. R. 
Pl. XXVIII, fig. 114. 
B. testa ovato-acuta, ventricosa, plicis longitudinalibus tenuibus striisque 
transversis decussatd, cinereo-ceerulescente ; anfractibus superné angulatis ; 
apertura subrotundata ; labro intus striato. 
Shell ovate, ventricose ; spire pointed, composed of six or 
seven whirls slightly angular at their upper part, loaded with 
very convex longitudinal folds near the suture ; these folds 
are less prominent, and more flattened upon the right lip of 
the lowest whirl. It is intersected by numerous transverse 
strie ; the upper extremity of the fold is sometimes separated 
by a stria which divides them superficially. Aperture ovate, 
white, terminated above by an emargination of the right lip, 
and by a transverse ridge of the left lip. Right lip thin, 
slightly denticulated at the base, furnished with numerous 
strie internally ; columella arcuated, covered by the left lip, 
which conceals, by its expansion, a part of the body of the 
shell, and forms a large, white, and polished callosity. The 
color of this shell is whitish, ash or bluish, sometimes without 
spots or bands, at other times with two or three deeper bands 
which surround the whirls. 
Length 1 inch. Width 8 lines. 
Inhabits the Indian Ocean. 
I think this shell is a variety of the Bucctnum arcularia. 
Gualtieri has already made this union with reason, because it 
does not differ enough from the last to be a different species. 
The folds and the strie cannot be considered as constant char- 
acters, and belong generally to young specimens ; and this Buc- 
ctnuM differs only from the one we have just described, in the 
whirls being much less flattened.
