MOLLUSCA OF INDIA. 101 



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." 



From specimen preserved by Dr. W. T. Blanford : — Animal 

 dark-coloured above ; sole of foot and the outer peripodial margin 

 pale in coutrast ; between the peripodial grooves dark-coloured, as 

 well as the segmental divisions above. Horn above mucous pore 

 well developed. The left shell-lobe and right shell-lobe both long 

 and tongue-like ; the left dorsal lobe rather small and narrow. 



A fine specimen from Rissom Peak, W. Bhutan, measures in 

 major diameter 8 mm. and is dark green in colour. 



MACROCHLAMrs FRAGosus, u. sp. (Plate CIX. fig. 4.) 



Localitij. Toruputii Peak, Dafla Hills {G.-A.). 



Shell scarcely perforate, globose, thin, translucent ; sculpture 

 fine microscopical regular longitudinal striae ; colour sap-green ; 

 spire flatly convex ; suture shallow ; whorls 3|, last swollen and 

 rounded at the periphery ; aperture semi-ovate ; columellar margin 

 perpendicular, not reflected, weak. 



Size: maj. diam. 6-7, min. 6"0 ; alt. axis 3*5, alt. body- whorl 

 2-8 mm. 



Since this shell was figured by me it has been considerably 

 damaged, but fortunately two other specimens should be preserved 

 in the Calcutta Museum. The specimen described above was sent 

 to me by Geofixey Nevill as 167 b of his ' Hand-list,' p. 39, under 



" Nanina {Microcystis), n. sp. 



" 3 Toruputii ; coU. Major H. H. Godwin-Austen. 



" 5 Sikkim ; coll. Dr. F. Stolicka." 



Specimens fi'om both localities came with the MS. name of per- 

 fragilis, the Sikkim species being marked 167 A ti/jye. They are not, 

 however, identical (compare figs. 4 & 5 on Plate CIX.). 



No example of 167 b, IL fragosus, occurs in my collection in this 

 country, which is thus explained : — After the punitive expedition 

 against the Dafla Tribe in 1874/75, I placed all the shells I had 

 collected in that part of the Eastern Himalayas in the hands of my 

 friend Nevill, to select what he wanted for the Museum and to work 

 them oat, which he only lived to partially do. Fortunately he sent 

 home some of the duplicates for me to figure and describe in this 

 work, and I have thus been able to clear up many of the species 

 recorded as new that are to be found in the ' Hand-list.'
