Carinodrillia

Carinodrillia buccooensis, from the Muséum national d’Histoire naturelle.

Belongs within: Pseudomelatomidae.

Carinodrillia is a genus of moderate-sized conoid gastropods known from the southwest coast of North America, as well as the Miocene of the Caribbean (Powell 1966).

Characters (from Powell 1966): Shell of moderate size, 14–35 mm, fusiform, with a tall spire of rather sagged turreted whorls, and a short body—whorl, rather quickly contracted to a moderately long to rather short slightly flexed weakly notched anterior canal. Protoconch of two depressed subcarinate smooth whorls. Adult sculpture of axial folds, spiral cords and threads; in the peripheral area, one or more of the overriding heavier spirals fuse over the axials to form low keels. Aperture narrow, with a thin outer lip, interrupted above by a deep narrow U-shaped sinus, restricted above by a moderate parietal callosity, at the termination of a prominent smooth subsutural fold. Colour uniformly whitish to brownish. Radula, a pair of simple slender curved non-barbed marginals.
