1-20 poll. Inhabits Cuba and Santa Cruz, and is closely allied 

 to P. rupicola, Say. 



Pupa lyrata. Testa parva, plerumque sinistrorsa, castanea, 

 late umbilicata ; anfr. 5 convexis, costulis flexuosis ad 20 concinne 

 clathratis ; apertura sub-orbiculari, eampanulata ; postice dentibus 

 duobus lamellosis, in faucibus duobus aliis armata. Long. 22-200;

Dr. Gould had examined the shells not long since an- 

 nounced as having been received from the Rev. Francis 

 Mason, missionary at Tavoy, in British Burmah. The 

 collection proves to be highly interesting ; a large, propor- 

 tion of the shells appearing to be hitherto undescribed, some 

 of which he proceeded to characterize, viz. 



Helix procumbens. Testa discoidea, supra planulata, subtus 

 convexa, epidermide pallide cornea, late umbilicata ; anfr. quatuor, 

 ultimo deflecto ; apertura rotundata, labro reflexo, albo. Diam. 

 3-4 ; alt. 1-4 poll. 



Belongs to the group of which H. planulata is the type. 



Helix infrendens. T. orbiculata, depresso-conoidea, corneo- 

 virescente, subcarinata, supra rugose striata, infra glabra, nitida, 

 regione umbilicali indentata ; anfr. 7 convexis, sutura impressa ; 

 apertura coarctata, labro vix reflexo, dentibus tribus pliciformibus 

 instructa. Diam. 2-5 ; alt. 1-5 poll. 



Very closely allied to H. Rangiana, Fer. 



Helix (Caracolla) gabata. Testa albido-cornea, supra planu. 

 lata, infra valde convexa, lata et profunde umbilicata ; anfr. 4 1-2, 

 leviter striatis, ultimo carina castanea circumdato; apertura sub- 

 quadrata, labro albo, reflexo. Diam. 4-5 ; alt. 7-20 poll. 



Much like H. scabriuscula in form and aperture, but quite dif- 

 ferent as to surface, color, and umbilicus. 



Helix (Caracolla) retrorsa. Testa orbiculata, sinistrorsa, 

 utrinque convexa, pallide castanea, arete umbilicata ; anfr. 5, lineis 

 longitudinalibus et volventibus minute rugosis, ultimo carinato ; 

 apertura rotundata, labro acuto. Lat. 1 3-4; alt. 1 poll. 



Young specimens might be confounded with H. Himalana, Lea, 

 which is much more rounded, the surface smoother, the carina 

 quite indistinct, and the umbilicus smaller. 



Helix (Caracolla) anceps. Testa lenticulari, pallide cornea
