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; peristomate valde incras- 
sato, reflexo, subtus latiori, marginibus callo junctis, columellari 
expanso, superne sinuato, extus angulum efformante, dextro me- 
dio antrorsum arcuato. 
Long. 43 mill., lat. 23; aperture long. perist. incl. 18 mill. Lat. 9 
millim. 
flab. prope Nanking, China. 
Brought by the late Dr. D. King, 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. 14 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 plicidens, 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 expanso 
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 pradito ; umbilico angusto. 
Long. 2 mill., lat. 15 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 J found it abun-
