"Cerion (Strophiops) fernandina, new species. Plate 3, fig. 5.

Description. ? Shell large, perforate, solid, subconical to sub­cylindrical, shining and nearly smooth. Color a flat white, nuclear whorls glass-like and opaque. Interior of aperture a very pale brownish yellow to cream. Whorls 10-11, nearly flat sided, first 7 to 9 forming the slightly convex cone of the spire. Occa­sionally the whorls, particularly the body whorls, may be slightly inset, forming a slight overhang with the whorl above. Body whorl usually the largest in diameter. Umbilical perforation generally large, located deeply in the broad excavated area behind the columellar lip. The excavated area is abruptly formed by the infolding of the base of the body whorl and in many specimens is wider below the edge. Parietal tooth short, centered and rather high but not penetrating very deeply within thc aperture. Columellar" teeth" composed of, usually two, very slight, irregu­lar, flattened and rather inconspicuous knobs, occasionally the upper one large enough to be called a tooth or lamella. Aperture subovate with only a slightly thickened, expanded lip which is usually flat though occasionally slightly folded back. Parietal wall calloused with a thickened ridge connecting the lip extremi­ties; it is, however, not built forward. Sculpture of coarse and irregular growth lines somewhat evenly disposed over the entire shell other than the nuclear whorls. These growth lines on cer­tain species are somewhat grouped forming a few ribs on the body whorl. Sutures only very slightly indented. The spire is pro­duced at an angle of approximately 60°. Length 34.3; width 16.5; aperture 9.2 x 5.8 mm. (holotype). Length 32; width 16.2; aperture 8.2 x 5.3 mm. (average of 8 specimens).

Holotype. ? Mus. Comp.  Zoöl. No. 65131, Millers, 8 mi. SE. of Simms, Long Island, Bahama Islands. J. V. Malone collector, Oct., 1936. (The name Fernandina was originally applied to Long Island by Columbus.)

Remarks. ? Though the general outline of this form appears to be quite different from C. malonei, they are apparently rather closely connected. C. malonei is in reality a widely divergent form and represents an extreme in the morphological develop­ment of the shell. Both of these forms possess an open umbilical orifice and similar lip and tooth characters. The present form exhibits but little variation in shape in comparison with C. ma­lonei, which from form modification is one of the most variable in the genus.

C. fernandina is a member of the regina group of Cerions and is patterned quite closely after C. regium of Castle Island on the Crooked Island Bank. It is a smaller species, however, and does not possess the rather sharply tapering cone of this latter form."  (Clench, 1937:21-22)
