 zone).] 



Shell subperf orate, globosely depressed, very thin, smooth, 

 polished, with traces of lougitudinal striatioii under the micro- 

 scope, not always to be detected, but best seen on the penultimate 

 whorl above and around the perforation beneath, tawny horn- 

 coloured ; spire lo^^', conoidal, suture impressed ; whorls 4.j, 

 convex, the last considerably broader, rounded at the periphery, 

 convex beneath ; aperture large, oblique, roundly lunate ; peri- 

 stome thin, the right margin slightly arcuate above, columellar 

 much curved, vertical in the middle, curving to\\ards the right 

 margin above, and briefly but rather broadly reflected, so as almost 

 to close the perforation. 



Major diam. 5, miu. 4|, height 3| mm. 



Hal>. Darjiling, and Senchal Mountain near Darjiling, 7000- 

 8000'. 



The animal was found creeping on shrubs ; it has long mantle- 

 lobes and a large lobe above the caudal gland, colour pale. The 

 shell may be recognized by its subglobose form. 



[Erom specimen preserved by Dr. W. T. Elanford : — Animal 

 dai'k-coloured above : sole of foot and the outer peripodial margin 

 pale ill contrast ; between the peripodial grooves dark-coloured, 

 as well as the segmental divisions above. Horn above mucous 

 pore w ell 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 Eissom Peak, W. Bhutan, measures in 

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