CUBAN SUBFAMILY CHONDROPOMINAE — TORRE AND BARTSCH 381 



Shell moderately large, when truncated almost subglobose, pale 

 orange-red. Nuclear whorls almost 2, inflated, strongly rounded, the 

 initial portion chestnut-brown, without sculj^ture. Postnuclear 

 whorls very strongly inflated, strongly rounded, narrowly sliouldered 

 at the summit, unicolor, marked by numerous slender retractively 

 curved axial riblets, which are only about one-fourth as wide as the 

 spaces that separate them and spiral cords of about the same strength 

 and spacing. The junctions of these two elements form minute 

 cusps, while the spaces enclosed between them are rectangular ])its 

 having their long axis parallel with the axial sculpture. Periphery 

 inflated, strongly rounded. Base inflated, strongly rounded, mod- 

 erately openly umbilicated and marked like the spire. This sculp- 

 ture also extends onto the umbilical wall, but here the axial riblets 

 become very closely approximated. The last whorl is solute for a 

 short fraction of a turn. Aperture very broadly ovate; peristome 

 double, the inner exserted and reflected quite distinct from the outer ; 

 the outer moderately broad, obliquely expanded and marked by 

 feebly concentric lamina, rendered crenulated by the external sculp- 

 ture. On the parietal wall, however, the outer peristome is much 

 narrower than on the rest of the turns. Operculum thin, paucispiral, 

 with subcentral nucleus and a fine granular deposit on the outside. 



Of the animal of this species Gundlach^^ says: "Below rocks and 

 dry leaves in shrubbery. The animal is light in color, dotted with 

 fine white clots, the snout and forehead are marked by minute dark 

 dots and is transversely sharply delineated. There are also some 

 fine dots between the antennae, which are cinnabar red with some- 

 what brownish tips. The head is reddish within, but the head it- 

 self, as well as the base of the tentacles, are white. The digestive 

 system is visible through the substance of the animal." 



The specimen figured, U.S.N.M. no. 493125, is a cotype collected 

 by Gundlach at the Estero en Cabo Cruz. It has 3.5 whorls remain- 

 ing and measures: Length, 11.8 mm; greater diameter, 8.7 mm; 

 lesser diameter, 7.2 mm.

Plate 39, Figtjbe 8 



Shell rather large, when truncated subglobular, flesh-color, with 

 interrupted spiral bands of brown, the dots composing which are 

 also arranged in axial series. Nuclear whorls 2.3, inflated, strongly 

 rounded, finely granulose, the initial portion dark chestnut brown. 

 Postnuclear whorls very strongly inflated, rounded, very narrowly 

 shouldered at the summit, forming a slightly channeled suture,
