GENUS BUCCINUM. 21 



composed of six whirls, whose length slightly exceeds that of 

 the aperture. The whirls of the spire are convex, bent 

 obliquely at the suture, and marked in that part, by slightly 

 projecting and distant longitudinal folds ; the lower whirl is 

 partially destitute of them, and those which are perceptible 

 there, are only slightly obvious upon the upper half of the 

 side of the aperture. The aperture is ovate, smooth ; the lips 

 are whitish, of a clear fawn-color, but the depth of the cavity 

 presents the same tint as the exterior. It is narrower towards 

 the base, where it terminates by a shallow emargination, the 

 edges of which are slightly curved towards the back. The 

 right lip is simple, sharp upon the edge and effuse. It has, 

 towards its upper part, an oblique fold, which seems to widen 

 the aperture, and which partially forms the obtuse angle. The 

 columella is almost straight, shining, and of a livid color. 



Length 15 lines. Width 7 lines. 



Inhabits the coasts of Peru, from whence it has been lately 

 brought in great abundance. 



This species is perfectly distinct from all others which com- 

 pose the genus BuCciNtrivfJ by the singularity of its aperture, 

 which is widened towards its upper part in the form of a gutter.
