slightly convex, and united by a pretty delicate regular suture. 
Aperture oblong ovate, effuse towards the base; right lip 
smooth and white, marked interiorly, at a short distance from 
the edge, with sixteen or eighteen transverse strie of a reddish 
brown ; columella slightly arched and whitish. © 
Length 16 lines. Width 9 lines. 
Inhabits the rocks of the Cape of Good Hope. 
This species resembles exceedingly the Buccinum testudi- 
neum; but it differs, nevertheless, in its form, which is a little 
more elongated, and in its more spreading aperture. Besides, 
the spots on the shell do not form transverse lines, but blotches, 
or longitudinal waved bands. The strie upon the interior of the 
aperture also do not exist in the Bucctnum testudineum. 
I have given to this shell the name of Delalande, who first 
made it known ; he obtained it in his voyage to Africa, a voyage 
so useful to science by the numerous collections which were 
made, and with which the Museum was enriched.
