GENUSBUCCINUM. 7 



transverse furrows ; spire composed of seven or eight whirls, 

 traversed by thick, noduled folds, somewhat oblique, and much 

 less apparent upon the lowest whirl, which is encircled by one 

 or two very apparent convex keels, which rarely exist upon the 

 upper whirls. Aperture whitish, rounded, deeply emarginat- 

 ed at its base ; right lip white, reflected, and slightly emar- 

 ginated at its upper part ; columella white and waved. 



Length 2 inches 9 lines. Width 16 lines. 

 Inhabits the Northern Seas. 



This species is distinguished from all others, by one or two 

 keels upon the lowest whirl, and by the thick noduled folds which 

 traverse the other whirls ; these folds are seen strongly promi- 

 nent, only upon this species and the BUCCINUM undatum. It 

 differs from that, by its form, and particularly by its aperture, the 

 lip of which is bordered by a very distinct varix.

Shell oblong, conical, rather thin, of a reddish brown color, 

 covered transversely with striae and ridges, with some slightly 

 apparent longitudinal striae ; the transverse ridges are raised 

 and very prominent ; spire elongated ; seven whirls to the 

 spire, convex and depressed at their upper part ; the low- 

 est whirl is longer than all the others together; aperture 

 elongated, ovate, of a reddish yellow, slightly emarginated at
