216 Land and Fresh- water Shells of the Himdlaga. [March, 



tern, (apice omissa) arete convolutis; apertura lunata, labro striga in- 

 crassata, interni distante munito." — Diam. 0.65. — (B.) 



Animal as in the genus ; the color a dark verdigris green. 

 This beautiful species is found in great abundance in the forest of 

 3fahassu, beneath fallen timber, and in the hollow trunks of decaying 

 trees; it is also plentiful at Fagd and Ndghunda, at 9,016 feet, and 

 has been met with at Hattu, at 10,656 feet. All these places have a 

 greater elevation than Simla, where it has not yet been discovered — 

 (H.) 



" The closely packed whorls shewing a larger number in a smaller 

 diameter, at once distinguished this species from all the darker colored 

 and more depressed varieties of Nanina vitrinoidesr — (B.) 



No. 5. Nanina vesicula, Benson. — Testa, tenui depressiuscula, pal- 

 lide cornea, translucente, polity, supra, conoida ; apice acuminata ; infra 

 tumidiuscula ; apertura? longitudine latitudinem sequante ; labro subrecto 

 ad axem spectante. — Diam. 0.6. Whorls six in number. 



" This shell has a wide geographical range, and is yet very local. Lieut. 

 Hutton first met with it between Neemuch and Mhow, and noticed 

 without naming it in the 3rd vol. of the Journal, p. 521. Mr. Benson 

 subsequently observed it at the effluence of the Bhagirathi from the 

 Ganges, and at Rajmahl, and noticed it as a novelty in p. 357, vol. 5. 

 Lieut. Hutton again met with it abundantly at Simla, where it pre- 

 serves the habit as at Rajmahl of climbing on plants, a circumstance so 

 rare with respect to * vitrinoides* that it can only be looked upon as a 

 casual exception to its custom of creeping on the earth, on rocks or 

 mossy masonry. The animals first taken by Lieut. Hutton, were 

 doubtless observed in too dry an atmosphere, as he then failed to re- 

 mark the extensile tentacular processes of the mantle which preserve 

 the fine polish of the epidermis ; and the oval process surmounting the 

 mucous pore must have been in a contracted state. 



" The straightness and vertically of the left lip of the shell, the great 

 comparative length of the aperture, and the acuminated spire abundant- 

 ly serve to distinguish this species." — (B.) 



No. 6. Nanina fragilis, Hutton — Testa tenui, fragili, vitrea, 

 olivacea, conico-discoidea; spira subexserta, apice obtuso; anfractibus 5, 

 supra convexis, subtiis subplanatis ; apertura obliqua, rotundato-ovata; 

 peritremate acuto." — Diam. 0.35 poll. — (H.) 



This small and fragile species was found at Kirmalliah, about 5 miles 

 from Neemuch, crawling over the leaves of the Dhak bush or Pulas 

 tree (Butea frondosa), on which it appeared to feed. It is a very thin 

 fragile species, and the smallest of any of the genus I have yet seen.
