obsciiri punctato-fasciatu et prope apicem. strigatd, 

 anfractibus cotivexis, dense minute reticulatis ; aper- 

 lurd obliqtie ovafd, laiissime Jimbriatd. 



The choice Chondropoma. Shell contractedly umbi- 

 licated, ovately conical, silky orange, obscurely dot- 

 banded with red-brown, and near the apex streaked, 

 whorls convex, densely minutely reticulated; aper- 

 ture obliquely ovate, very broadly fimbriated. 



Ci/closloma egregium, Gundlaeh, in Poey, Mem. vol. ii. p. 

 13.pl. 1. f. 13. 

 Chondropoma egregium, Pfeift'er. 



Rab. Cuba; Gundlaeh. 



The specimen of this beautiful species here figured is a 

 bright silky orange colour. Dr. Pfeifler describes a dark 

 violet variety, and there are probably many others. 



Species 4. (Mus. Cuming.) 



Chondkopoma Siiuttleworthi. Chond. testa clause 

 umbilicatd, tumido-conicd, subcyliudraced, fulvd, dia- 

 pliund, riifescente-fusco interrupte taniafd, pone la- 

 bruni radiald, avfrnctibiis rude convexis, spiraliter 

 filo-slriatis, versus apicem minute reticulatis ; aperturd 

 oblique otJatd, sitbsolutd, latissime Jimbriatd, fimbrid 

 fusco-radiatd. 



Shuttlewokth's Chondropoma. Shell with closed 

 umbilicus, tumidly conical, subcylindrical, fulvous, 

 diaphanous, interruptedly filleted with red-brown, 

 rayed behind the lip, whorls rudely convex, spirally 

 thread-striated, minutely reticulated towards the 

 apex ; apertiu'e obliquely ovate, slightly detached, 

 very broadly fimbriated, fiill x'ayed with brown. 



Ci/clostoma Shuttleicorthi, Pfeifler, Pro. Zool. Soc. 1851, 

 p. 246. 



Chondropoma SJiultleworthi, Pfeiffer. 

 Cyclostoma verecuudum, Poey. 

 Chondropoma verecuiuhmt, Pfeiffer. 



Ilab. Cuba. 



This is a very thin semitransparent shell, finely decus- 

 sately sculptured, but the longitudinal sculpture soon dis- 

 ajjpears, leaving the spiral scidpture well defined through- 

 nut. 



Species 5. (Fig. a, b, Mus. Cuming.) 



Chondropoma pictum. Chond. testd compresse umbili- 

 catd, oblongo-coidcd, parum cyVmdraced, fulvo-albidd, 

 diaphand, pniictis ustulato-fuscis promiscue strigatd, 

 interduni nigro-violaced, labro aurantio, anfractibus 

 snbtumido-convexis, liris tenuibus spiraliter confertim 

 funiculatis ; aperturd oblique otatd, labro subincras- 

 sato, coniinuo. 



The painted Chondropoma. Shell compressly um- 

 bilicated, oblong conical, but little cylindrical, ful- 

 vous-white, diaphanous, promiscuously streaked with 

 burnt-brown dots, sometimes dark violet, with the 

 lip orange, whorls rather tumidly convex, closely 

 spii-ally corded with fine ridges ; aperture obliquely 

 ovate, lip rather thick, continuous. 



Cyclostoma pictum, VfeiSer, Wiegm. Arch, fiir Nat. 1839, 

 vol. i. p. 356. 



Cyclostoma Sagra, D'Orbigny. 

 Cyclostoma Mahogani, Gould. 

 Cliondropoma pictum, Pfeiffer. 



Hab. Cuba. 



Ver\' definitely and regidarly corded throughout, with 

 fine ridges, the interstices between which are not reticu- 

 lated, but striately punctured. This species has been 

 sometimes mistaken for C. TFeinlandi, in which the ridged 

 sculpture runs in the opposite direction. 



Species 6. (Mus. Cuming.) 



Chondropoma Habichii. Chond. testd compresse um- 

 bilicatd, ovato-conicd, diaphano-albd,ferrugineo tinctd, 

 fusco sparsim punctato-fasciatu, anfractibus subrotun- 

 datis, longitudinaliter Jilo-liratis, liris creberrimis, 

 subfimbriatis ; aperturd oblique ovatd, labro late cat- 

 loso-expanso. 



Habiche's Chondkopoma. Shell compressly umbili- 

 cated, ovately conical, diaphanous white, tinged with 

 rust, sparsely dot-banded with brown, whorls rather 

 rounded, longitudinally thread-ridged, ridges ver}- 

 close set, slightly fimbriated ; aperture obliquely 

 ovate, lip broadly callously expanded. 



Weinland, Malak. Blat. 1863. 



Hab. Island of Haiti ; Weinland. 



Scidptured with close-set longitudinal thread-stria' of 



semi-dia])hanous substance, like C. mngnificum, a little 



fimbriately waved.
