The bro.\d Chonduopoma. Sliell largely excavately 

 umliilioated, depressly globose, straw-colour, whorls 

 rounded, obliquely delicately thread-striated, conspi- 

 cuously keeled at the umbdicus ; aperture circular, 

 partially fimbriated. 



GcNDLACH, MS. in Mus. Cuming. 



Halj. Cuba. 



A very distinct form of the genus, in whicii the shell is 

 depres?'y globose and largely deeply undjilicated, the um- 

 bilicus being prominently keeled throughout. 



Species 57. (Fig. a, JIus. Cuming.)

The MARIN i; Choxdropoma. Shell rather compressly 

 umbUicated, oblong-turreted, fulvous, longitudinally 

 streaked with double rows of chestnut dots, banded 

 at the base, wdiorls convex, longitnilinally densely 

 thread-ridged, crenulated at the sutures ; aperture 

 obliquely ovate, a little expanded, rayed. 



Weinland, Malak. Blat. 1863. 



Bab. Island of Haiti ; Weiuland. 



Probably named marinum from the circumstance of its 

 being found in the vicinitv of the sea.

The base-keeled Choxdkopoma. Shell compressly 



umbilicated, oblong-turreted, dead white, semifossil, 

 whorls flatly convex, spirally superficially ridged, with 

 oblique scabrous striiB passing over them, last whorl 

 keeled at the base ; aperture obliquely circular, de- 

 tached, keeled at the upper part, lip slightly fimbri- 

 ated. 



Ci/closfoma basicarinatum, Pfeiffer, Malak. Blat. 1855, p. 

 101. pi. 4. f. 2, 3. 



Hab. Cuba. 



A dead-white semifossil shell, belonging to a type of the 

 genus, of which there are many other species of smaller 

 size.

 closed umbilicus, cylindrically oblong, rather solid, 

 transparent rose-tinted, whorls flatly convex, mimitely 

 thread-reticulated throughout, slightly crenulated at 

 the sutures ; aperture obliquely circularly ovate, lip 

 callously fimbriated, white. 



GuNDLACH, MS. in Mus. Cuming. 



Hab. Cuba. 



A very distinct form of Clioudrojwmn, of solid growth, 

 but yet of transparent rose-colonr, white at the lip. 



Species 60. (Mus. Cuming.)
