Shell large, helicoid, the early whorls red, the last one pale brown 

 with the appressed summit almost white. The nucleus consists of 

 1.5 well-rounded smooth turns. The rest of the whorls are marked 

 by rather strong axial ribs, which are about as wide as the spaces 

 that separate them. They are very regular on the early turns but 

 become less so on the last whorl owing to the additional wrinkled 

 sculpture. Beginning with the fourth turn, rather large, feebly de- 

 veloped, and irregularly distributed wrinkles, which fade out on the 

 last part of the last turn, make their appearance. These wrinkles 

 are best emphasized below the appressed summit. Suture strongly 

 impressed on all but the last turn where the summit creeps up on 

 the preceding turn and forms a cord. Periphery well rounded and 

 marked by the wrinkling characteristic of the upper surface of the 

 last turn. Base inflated, strongly rounded, moderately broadly, 

 openly umbilicated and marked by a series of very strong, oblique, 

 retractively slanting, short cords, which radiate from the outer edge of 

 the umbilicus, but do not reach the middle of the base. The spaces 

 separating these cords are not quite as wide as the cords. The rest of 

 the base is feebly malleated. The umbilical wall is marked by obsolete 

 ribs, which are the continuation of the strong oblique cords mentioned 

 above. These, as well as their interspaces, are crossed by incremental 

 lines. Aperture circular, oblique, decidedly protracted into a clawlike 

 clement at the posterior angle ; the outer lip of the peristome is exca- 

 vated below the summit and protracted on the middle, thin at the edge, 

 with the inner lip thickened. Operculum typically cyclopilsbryid. 



The specimen figured is one of two, U.S.N.M. No. 366099, received 

 from C. B. Adams. It has 5.5 whorls and measures: Height, 19.2 

 mm.; greater diameter, 23.8 mm.; lesser diameter, 17.3 mm. It is 

 without specific locality label. 



The species appears confined to the south side of Westmoreland 

 Parish, Jamaica, east of Savanna la Mar.
