Cerion ornatum Pilsbry and Vanatta, 1899

Original Description

"[Cerion torrei ] var. ornatum P. & V. Figs. 3, 4

Similar in form to the longer specimens of C. torrei, but strongly and regularly ribbed throughout, the ribs on the cylindrical portion 1-2 mm. apart, and decidedly narrower than the intervals; parietal margin of peristome more elevated.

Vita, Cuba.

This looks like a distinct species, but is merely the costate form of the preceeding [C. torrei].  It is more slender than the ribbed form of C. dimidiatum, with finer ribs, continued upon the terminal cone, and there is no basal keel."  (Pilsbry & Vanatta, 1899:476-477)
