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 Buccinum, by the singularity of its aperture, 
which is widened towards its upper part in the form of a gutter.
