Cerion hologlyptum Pilsbry, 1902

Original Description

"Pupa sagraiana PFR., Zeitschr. f. Malak., 1847, p. 15; Mal. Bl., i, 1854, p. 206; Monogr. ii, p. 322; iii, 539; iv, 658; vi, 290; Conchyl. Cab., p. 121, pl. 16, f. 4, 5.—SOWB., C. Icon., pl. 3, f. 19.

—ARANGO, Fauna Mal. Cubana, p. 101.—Strophia obscura MAYNARD, Contrib. to Sci., iii, p. 21, pl. 3, f. 5, 6 (March, 1896).

      The typical form (pl. 30, fig. 77) was small, 22-24x9 mill., smooth and marbled. Pfeiffer mentions the following forms:

   (b) Smaller, 17-18 mill. long, 8 wide. Punta de Jicaco, (probably  Punta Icacos, N. from Cardenas).

   (c) Large, the last whorl plicate; length 30, diam. 11 mill. Cayo Piedra.

   (d) Still larger, with strongly developed peristome and distinct rib-striæ; marbled; length 36, diam. 11 ½ mill. Or marked with darker streaks. Cayo Blanco.

       The series before me shows all gradations between elaborately marbled and uniform whitish and flesh-tinted specimens. Sometimes the lower 4 whorls are smooth, sometimes the last is finely plicate at the base or throughout, or at base and near the suture. These lead to the form d, which for convenience may be called form hologlyptum (pl. 30, fig. 83), which is evenly and closely costulate throughout, and either marbled with pale flesh-brown on a whitish ground, or fleshy-brown, speckled with white, or with whitish riblets.

      Specimens from Cayo Piedra del Norte (R. Arango) vary from chalky white sparsely maculate with gray on the cone, to the usual marbled pattern. They are nearly smooth, and measure from 29x12 to 26x10 ½ mill.

      Form obscurum Maynard (pl. 30, figs. 81, 82). Rather thick and heavy, smooth, bluish-white, obscurely marked with zigzag longitudinal lines of very pale yellowish-brown, scarcely to be seen on the lower whorls, better developed on the cone of the spire. Whorls 9. Length 27 ½, diam. 10 ½ mill. Varying from 24 ½ to nearly 29 mill. long. Cayo Birde del Norte, Cuba. This seems to be practically typical sagraianum. I can find no difference whatever.

      There are some small, smooth specimens, pinkish-white with indistinct flesh colored stripe-marbling, the last whorl bluish-white, in the collection of the Academy, labeled "Holguin, Cuba, Dr. Candelaria Herrera." This is far out of the well-established range of the species, and may be erroneous, especially as that place is inland."
