"CERION (STROPHIOPS) JULIAE, Sp novo Plate 8, fig. 6.

Shell medium to large, solid, ribbed, cylindro-conic and rimately perforate. Color a dull white with rather faint axial bars of pale brown between most of the ribs. Whorls 11, widest at the mid area of the shell, tapering slightly below and tapering convexly to a slightly acute apex above. Interior of aperture a dull, creamy brown. Nuclear whorls dull white and smooth. From the second whorl onward the ribs appear, first very faintly and then becoming very strong on the later whorls. Umbilical rimation fairly deep but definitely closed within and very faintly margined by a basal ridge. Parietal ridge central and very well developed and not continued within for more than one-half whorl. Columellar lamella centrally located and only slightly developed at the aperture, much stronger within and is con­tinued back for two whorls where it gradually and smoothly merges with the axis at its upper point. Lip subquadrate, slightly collared, ridged or complete along the parietal region. Sculpture of strong axial ribs numbering 15 on the body whorl with numerous and very fine supplementary short ribs inter­sposed between the larger ribs at the bast of the last whorl.

Length 32.1, width 12, aperture 9 x 6.5 mm.

Holotype. ? Mus. Comp. Zoöl, no. 10369, Great Ragged Cay, southeastern part of the Great Bahama Bank, Bahama Islands, Alexander Agassiz collector, Feb. 10, 1893, "Wild Duck" Expe­dition.

Remarks. ?Unfortunately, only a single specimen of the new species is available for study. Dall¹ [¹Dall, W. H., 1894, Bull. Mus. Comp. Zoöl, 25, pp. 113-123 and plate] who worked up the material collected by the" Wild Duck" Expedition referred this specimen to C. cinereum (Maynard) (p. 119), C. cinereum, however, is only a colonial form of the more wide spread and abundant C. glans (Kiister) of the New Providence and Andros Islands. Though a member of the glans assemblage, it bears no direct relationship with that species.

            It appears to be fairly close to C. josephinae Clench from Long Island, a relationship which is expressed geographically as well. It differs from this latter species by being colored, possessing fewer and somewhat coarser ribs, a much stronger axial lamella and not having the inner margin of the umbilical rimation definitely margined. All other characters approximate C. josephinae.

            Great Ragged Island is one of the last of a chain of islands on the southeast end of the Great Bahama Bank, an area known as the Columbus Bank. From this island there is a long series of small Cays forming an arc which reaches nearly to Long Island." (Clench, 1936:112-113)
