Ig GENUS BUCCINUM. 



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 striae 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 striae upon the interior of the 

 aperture also do not exist in the BUCCINUM 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.

Shell oblong-ovate, of a red brown, furrowed throughout its 

 whole extent by regular transverse striae, numerous, pretty 

 near, interwoven by other very fine longitudinal striae ; spire 

 pointed, composed of seven whirls, each whirl, except the 

 lowest, adorned with longitudinal tubercles or ribs ; the colu- 

 mella projecting a little above an incipient umbilicus, which 

 penetrates it at the base of the emargination. Aperture 

 ovular, provided with a callosity upon the left lip, which is of 

 a beautiful reddish color ; lip arched, plaited upon the internal 

 edge as often as there are striae externally.
