 Weinland, Malak. Blat. 1863. 

 TIab. Bahama Islands. 



Very distinct from any of the preceding species, but 

 of precisely the same generic type. It is of rather solid 

 growth and very characteristic in colour — a bright flesh- 

 orange, without any marking, pink towards the apex, 

 oransre-red in the interior.

The narrowed Chondropoma. Shell rather narrowly j 

 turreted, fulvous, banded with linear blotches of 

 purple-chestnut, whorls convex, reticulately thread- 

 ridged, auriculately crenated at the sutures ; aperture

Uab. ? 



The habit of C. angustatum is not kno\vn, but there can 

 be little doubt of its being a West Indian species. 



The brought Chondropoma. Shell compressly umbi- 

 licated, rather narrowly turreted, nearly white, dia- 

 phanous, streaked with brown spots between the 

 ridges, whorls rounded, neatly spii'ally corded with 

 fine ridges ; aperture obliquely ovate, scabrously 

 fimbriated.

Clwndropoma 'perlatum, Pfeiffer. 



Bab. Cuba. 



An extremely delicate shining diaphanous shell, stringed 



transversely with very fine pellucid ridges. 



Species 30. (Mus. Cuming.) 



Chondropoma perlatum. Chond. testa compresse um- 

 bilicatd, subanguste turrild, viargaritaced, diaphand, 

 maculis fiiscis inter liras strigatd, anfraciihus rotun- 

 datis, liris tenuibus nitide spiraliter funiculatis ; aper- 

 turd oblique ovatd, scabroso-fimbriatd. 



Species 31. (Mus. Cuming.) 



Chondropoma Tortolense. Chond. testa compresse 

 umbiUcatd, ovato-turritd, albidd, maculis rnfo-fttscis 

 inter liras sparsim strigatd, anfractibus rotundatis, ad

The sculpture and marking of this shell is not much 

 unlike that of the preceding, but coarser and more opake. 

 The lip is of qiute another character, not being fimbriated.
