tinge and polish, this shell is distinguished from H. Hodgsonij 

 Blanford, by the narrow but more distinct margination of the 

 suture, its more depressed spire, fewer whorls, and by the absence 

 of any degree of compression at the periphery. It inhabits 

 a region varying from 7000 to 8000 feet, living, according to 

 Mr. W. T. Blanford, on succulent shrubs.

 culo ; apertura subobliqua, subquadrato-rotundato-lunari, peristo- 

 mate tenui, recto, margine columellari subverticaliter descendente,

 Habitat at Pankabari, in regione calidiori Terai. 



A single worn specimen of this species is in the Collection. 

 In form and many characters it so nearly tallies with a little 

 undescribed shell which I collected at Mussoorie and Landour, 

 that I feel much disposed to unite them ; but the greater com- 

 parative solidity of the Darjiling specimen, the caducous epider- 

 mis, and the circumstance of the margins being united by a 

 callus, of which there is no trace in any of my Western speci- 

 mens, make it undesirable to confound them until a series of 

 the Darjiling species can be had for comparison. The species 

 was probably named by Mr. W. T. Blanford either after the 

 distinguished engineer. Col. J. A. Hodgson, who first explored 

 Darjiling, and wrote a paper on its topography, which was pub- 

 lished in the ' Gleanings in Science,' — or after Mr. Brian H. 

 Hodgson, formerly Resident at the court of Nipal, and latterly 

 residing at Darjiling, whose diligent investigation of the Mam- 

 malia and Birds of those regions is well known to naturalists.
