MI8 Mr. W. H. Benson on new Species o/Pupa. 



circumstante ; apertura valde obliqua, lata, ovato-lunari ; peristo- 

 raate non continuo, superne expansiusculo, subhorizontali, infra 

 reflexiusculo, marginibus conniventibus approximatis. 



Diam. major 13, minor 10, alt. 4 mill. Apert. lata 5i, 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-continuous 

 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, laevigata, translucente, 

 vitrea ; spira ovata, apice obtuse, 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, laevigata, tenui, pallide 

 cornea, translucente ; spira obtuse ovata, sutura impressa ; anfrac- 

 tibus A\, convexiusculis, ultimo antice vix ascendente ; apertura 

 obliqua, edentula, angulato-rotundata ; peristomatis marginibus 

 remotis, dextro recto acuto, columellari expansiusculo. 



Long. If, 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 620 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 

 nnder the MS. name of Helix contracta.
