Epitonium lowei

Author: McLean J.H. & Gosliner T.M.

Description

Description. Shell white, medium in size, up to 9 rapidly expanding whorls, umbilicus deep; costae 25-32, slightly spinose at the shoulder, with some costae larger than the others; spiral sculpture of raised spiral ridges; sulci between ridges twice width of ridges. Length 15-25 mm.
Type Locality and Type Specimens. Oft Avalon, Santa Catalina Island, California, 40-60 fathoms. Holotype: lost (DuShane, 1979); paratype USNM 191548. Material Examined. California: Santa Maria Basin, Phase II, sta. R-2, 161 m (1); sta. R-4, 92 m (1); sta. R-8,90 m (1). Other material: 18 lots in the LACM collection.
Distribution. Santa Maria Basin, California (35°N) to Bahia Magdalena, Baja California Sur (24°N), and the Gulf of California. DuShane (1979) placed the northern limit at Anacapa Island, California, so the present material constitutes a significant range extension. DuShane's (1979) record of the species from Panama was based on a specimen of 5 mm in length and needs to be confirmed by specimens of larger size.
Habitat Soft bottoms, 25-170 m (DuShane, 1979:103).
Remarks. This species resembles the Epitonium bellastriatum (Carpenter, 1864), which occurs in shallower water, but is larger and more slender. These two species are assigned to the subgenus Asperiscala, characterized by the spiral sculpture.
