Conus prototypus (Guppy, 1874)

Description.

Somewhat pyriform, finely striate anteriorly, becoming quite smooth on the angle of the whorls, which bear a rather indistinct keel ; spire mucronate, rather elevated ; aperture somewhat widened towards the anterior canal.

Miocene, Saranetta, Trinidad.

A cone which departs very considerably from the usual type in its swelling outlines and the consequent direction and shape of the aperture. It is more of the shape of C. bulbus than of any other species I know. It is, however, probably a young specimen.
