" CERION HUNTINGTONI, new species Plate 3, fig. 1-3

Description. Shell subcylindrical, stout, solid, with the umbilical rimation closed or only minutely open. External color a chalk-white with the interior of the aperture a pale, creamy brown. Whorls 9½  to 10½ , last three, somewhat flattened, remaining earlier whorls sharply tapering to an obtuse summit. Spire somewhat short, conic, and slightly convex, produced at an angle of 83° (holotype) [A series of 10 specimens, however, gave a variation of this angle from 73º to 85º]. Aperture subovate to nearly circular. Parietal tooth strongly developed, cen­trally located and about three times as long as high. Columellar lamella much smaller but carried back for a full whorl. Lip expanded, flattened and generally recurved. Parietal lip well thickened, usually enough to connect the insertion points of the palatal lip. Suture well defined, sharply though not deeply indented. Sculpture generally of strong and widely spaced ribs, variable in number (18-23) and occa­sionally nearly obsolete. Nuclear whorls (1½) smooth. Basal ridge inconspicuous, the ribs continuing into the umbilical rimation.

Holotype. Mus. Compo Zool. no. 106956, Columbus Point, S. E. tip of Cat Island, Bahamas, E. Williams collector, July, 1935. Paratypes (2000±)  from the same locality.

Remarks. This species is materially different from all others en­countered on this island and the only species of the regina group known to occur on Cat Island. In relationship, it appears to be closely related to C. fairchildi Clench from Conception Island which is located about 25 miles S. E. of Columbus Point. It differs from that species in being a little smaller, more coarsely ribbed, has a less produced spire and a very much darker coloration within the aperture. A single colony only of this species was collected."  (Clench, 1938:526)
