126 Mr. W. H. Benson on new Asiatic species of the genus Pupa. 



ab axe deviante, intus fulvida ; plica columellari profunda, dupli- 

 cata, parietali elongata, remotiuscula ; peristomato valde incras- 

 sato, reflexo, subtus latiori, marginibus callo junctis, columellari 

 expanse, superne sinuato, extus angulum efformante, dextro me- 

 dio antrorsum arcuato. 



Long. 43 mill., lat. 23 ; aperturse long, perist. incl. 18 mill. Lat. 9 

 millim. 



Hab. prope Nanking, China. 



Brought by the late Dr. D. Kino;, H.M.S. Cornwallis, and pre- 

 sented by him to Dr. Cantor, to whose kindness I am indebted 

 for the specimen. A wire introduced into the umbilicus will 

 reach within a short distance of the summit. 



2. Pupa Huttoniana, nobis. 



T. rimata, ovato-oblonga, subcylindracea, hyalina, glabra, apice ob- 

 tuso ; anfractibus 5 convexis ; apertura ovato-rotundata, quinque- 

 plicata ; peristomate expansiusculo, marginibus callo tenui junctis ; 

 plica unica irregulari, sinuata, parietali, columellaribus duobus, 

 palatalibus duobus profundis. 



Long. 11 mill., lat. vix 1 mill. 



Hab. rarissime ad Simla montibus sub-Himalayanis occidentalibus ; 

 Hutton. 



This species (unlike most of the smaller Simla species of land 

 shells) has not hitherto been taken in other parts of the Hima- 

 layan chain. 



3. Pupa plicidenSj nobis. 



T. umbilicata, ovato-conica, subtrochiformi, glabriuscula, obscure 

 striata, cornea ; anfractibus quinque convexis, ultimo ventricoso, 

 antice ascendente, ad basin tumido ; sutura impressa ; apice ob- 

 tuso ; apertura irregulari, subtriangulari, 9-plicata ; peristomate 

 continuo, sinuato, expanso, marginibus callo appresso expanse 

 junctis ; dextro medio extus impresso, intus tuberculato-incras- 

 sato ; plicis parietalibus 3, quarum 2 superioribus elongatis, colu- 

 mellari dentiformi, unica, palatalibus 5, quarum 2 sub-basalibus 

 minutis ; margine basali extus callo prsedito ; umbilico angusto. 



Long. 2 mill., lat. 1^ mill. 



Hab. ad Landour et Mussoorie, montibus Himalayanis. 



The shell is very peculiarly formed, and seems to indicate the 

 transition from Pupa to Anastoma. 



The animal has four tentacula, the superior pair bearing the 

 percipient points or eyes, the inferior very short. The foot is 

 hyaline, the tentacula and neck fuscous. The shell is carried 

 horizontally. It is very local, although tolerably abundant where 

 found. It creeps among moss, on damp rocks, generally in places 

 which are seldom or never visited by the sun, in some of the lofty 

 and precipitous glens of the mountains near Landour. It seems 

 to be a capricious species. On a rock on which I found it abun-
