Cerion longidens Pilsbry, 1902
"C. LONGIDENS n. sp. Pl. 32, figs. 23, 24.
Shell shortly rimate, oblong or subcylindric, very solid and strong;
flesh-colored with nearly white ribs. Sculpture of strong, rather
close, subregular ribs. about 30 in number on the penultimate whorl;
on the last whorl the ribs become lower and split at the periphery,
so that the base is rather finely, irregularly rib-striate. Whorls 9 in
short, to 10½ in long specimens, but slightly convex, the last broadly
rounded below. Aperture ovate, whitish or pale within; peristome
reflexed and recurved, strongly thickened, white or pale reddish
brown; parietal callus rather heavy. Parietal lamella low and
rather slender but very long, extending inward to the dorsal side,
only slightly curved. There is a low callus or accessory tooth on
the left side of the outer end of the parietal lamella. Axial lamella
small at the aperture, strong within.
Length 24, diam. 11.5 mill.
Length 22.5, diam. 10.5 mill.
Length 26.5, diam. 10.8 mill. Cuba: Cabo Cruz (Bland).
This species has a long parietal lamella like the Little Cayman
species. In general external appearance it approaches typical C.glans
. The embryonic whorls are either ochre-colored or white." (Pilsbry, 1902:212)
