Original Description

"Cerion torrei moralesi, new species

(Plate 11, figs. 13, 14)

Cerion moralesi Torre, ms. (in sched.)

     Description. - Shell about 36 mm. in length (about 1½ inches) rather strong instructure, nearly smooth and rimately perforate. Color a grayish-­white to light brownish yellow and generally mottled or marbled with irre­gular, axial streaks of white. Whorls 11½, the last 3 nearly straight sided, the remaining earlier whorls forming a slightly convex, conic summit. Spire somewhat extended and forming an angle of 55° to 60°. Aperture subquadrate. Parietal lip thickened and reflected. Palatal lip nearly straight and built forward as a slightly thickened ridge. Palatal tooth centered, small and short. Columellar tooth small and extending backward for nearly a whorl. Columella short and nearly straight. Umbilicus exists as a small rimation which is par­tially hidden by the reflected lip. Suture slightly indented. Sculpture consist­ing of rather fine axial costae, paticularly on the early whorls. A few speci­mens are faintly costate on all whorls. Nuclear whorls pale amber color. The first whorls smooth, the remaining whorls very faintly costate.

     Types. - Holotype, Museo Poey no. 17293, and paratypes, Mu­seum of Comparative Zoölogy no. 187476, from Playa de Morales 11 kilometers S. E. of Banes, Oriente, Cuba, collected by C. G: Aguayo, W. J. Clench and A. Quiñones in July 1945. Additional paratypes from Playa Larga, 2 kilometers N. W. of Cabo Lucrecia; Punta de Mulas (PI. 11, fig. 13) ; and Punta del Puerte, all near Banes, Oriente, Cuba.

     Remarks. - The various localities given above cover a distance of about 25 kilometers, though the species is not at all continuous along this coast. Other species occupy intervening territory.

     This is a relatively large species and is a member of the vulne­ratum complex. This complex is composed of shells that are relatively smooth and possess a coloration ranging from very pale yellowish to a rather dark brownish-red which is generally mottled or marbled with white.

     In relationship moralesi is fairly close to Cerion torrei Pilsbry and Vanatta from west of Puerto Vita, a locality about 40 kilo­meters west of Punta Lucrecia the westernmost locality at which C. moralesi was found.

     C. moralesi diffE'rs from C. torrei  by being much larger, possess­ing a more conic summit, being much smoother and by being somewhat lighter in structure.

     Mr. A. Quiñones collected a large series of C. moralesi at a dif­ferent area at Playa Morales that were much smaller than the typical series, the smallest measuring 19 mm. in length.

     This species was discovered a few years before, by Mr. Alberto Quiñones, from Banes, Oriente." (Clench & Aguayo, 1951:77-78)
