138 Mr. W. H. Benson on new Species of Pupa. 
circumstante ; apertura valde obliqua, lata, ovato-lunari; peristo- 
mate non continuo, superne expansiusculo, subhorizontali, infra 
reflexiusculo, marginibus conniventibus approximatis. 
Diam. major 13, minor 10, alt. 4 mill. Apert. lata 54, alt. 4 mill. 
Habitat prope Mhow, Malwa. Detexit Capt. T. Hutton. 
This shell approaches H. Nilagirica, Pfr., but may at once be 
distinguished by its narrower umbilicus, showing only one and 
a half less convex whorls, by its flatter spire, different surface, 
and less suddenly deflected last whorl, which is subangulate 
and not rounded at the periphery, also by the non-contmuous 
peristome. It occupies an intermediate place between the 
southern H. Nilagirica and the Bundelkhund H. asperella, Pfr., 
first taken by me in 1824, also taken at Mhow by Capt. Hutton. 
It is worthy of remark that on the underside of H. Nilagirica 
there is a tendency to granulation like that of H. asperella, but 
that H. contracta presents no trace of it*, 
Pupa Thibetica, B. 
P. testa rimato-subperforata, oblongo-ovata, levigata, translucente, 
vitrea ; spira ovata, apice obtuso, sutura impressa ; anfractibus 5, 
subconvexis, ultimo antice ascendente; apertura obovata, 6-pli- 
cata, plica 1 parietali angulari, secunda inferiore profunda, denti- 
bus 2 columellaribus duobusque palatalibus profundis munita ; 
peristomate tenui, expansiusculo, margine columellari reflexiusculo. 
Long. 2, diam. 1 mill. 
Habitat ad Iskardo, Thibet. Detexit Dr. Thomson. 
This shell, received some years ago through Mr. Woodward 
of the British Museum, is nearly allied to P. Huttoniana, Bens., 
to which I erroneously referred it originally ; but, on close exa- 
mination, perfect specimens exhibit two parietal plaits, one of 
which is remotely seated, and in some positions is not easily 
detected. 
Pupa Gutta, B. 
P. testa obsolete rimata, oblongo-ovata, levigata, tenui, pallide 
cornea, translucente; spira obtuse ovata, sutura impressa; anfrac- 
tibus 43, convexiusculis, ultimo antice vix ascendente; apertura 
obliqua, edentula, angulato-rotundata; peristomatis marginibus 
remotis, dextro recto acuto, columellari expansiusculo. 
Long. 13, diam. 1 mill. 
Habitat in valle Spiti, Kunawurensi. Detexit W. Theobald. 
A single specimen, apparently adult, was received from Mr. 
* On referring to Capt. Hutton’s description of an unnamed Carocolla, 
in page 520 of the ‘Journal of the Asiatic Society of Bengal’ for 1834, 
which was found by him between Nimuch and Mhow, I have come to the 
conclusion that it is intended for the shell subsequently received from him 
under the MS. name of Helix contracta.
