﻿1874}. 1 from Assam and tlie Nag a TliJJs. 147 



I have an Alycaus from Daijeeliiig, found by Mr. F. Stollczka, but as 

 I possess but a a single much worn specimen, I hesitate to describe it more 

 fully: it is very similar to A. Tlieolaldi, Bs. from the Khasi Hills, but is 

 smaller with a more expanded aperture ; peristome less thickened, and the 

 sculpture appears to have been very fine ; I name it A. lenticulus, and trust 

 some day to get other specimens. Dimensions, major diam. 0'14'/' minor 

 diam. 11," alt. 008". 



Altcj^us Stoliczktt, n. sp., PI. III. Fig. 3. 



Shell globosely turbinate, thick, pale horny, finely and closely ribbed 

 from the swell of the first whorl as far back as the end of the sutural tube, 

 thence to the apex distantly and finely costulated ; narrowly umbilicated, 

 spire conoid ; apex blunt ; suture well impressed. Whorls 4|^, rounded, the 

 last swollen, then sharply constricted close to the origin of the sutural tube, 

 again swelling and expanding to the mouth. Constriction smooth with a 

 few distant lines of costulation. The sutural tube peculiarly long. Aper- 

 ture oblique, circular ; peristome double, outer lip small, the inner much pro- 

 duced and expanded into 2 broad shallow channels on the inside of the outer 

 margin separated by a V-shaped thickening of the same (see Fig. 3^). 

 Operculum black, concave, of the usual multi-spiral form.

Hahitat. — Two specimens were obtained for me by Mr. Belletty on 

 Angaoluo Peak, Naga Hills at 7,000 feet, during field season of 1872-73. 

 I found it again further to the east at Kezakenomih, and at the head of the 

 Lanier Eiver at about 5,000 feet where the specimens were much larger. It 

 comes near to the forms of A. Ingrami, W. Blf. var. (PI. IV and V, J. A. S. 

 Bengal, Vol. XL, Pt II, 1871) from the same range of mountains, but its 

 tumid shape, and particularly the very produced aperture, render it a very 

 distinct and well marked species. I have named it after that very accom- 

 plished conchologist F. Stoliczka* of the Geological Survey of India. 



ALYCiEUS GLOBULUS, n. sp., PI. III. Fig. 4. 



Shell moderatel}^ umbilicated, globosely turbinate, white, finely costula- 

 lated on the swell of the first whorl, becoming gradually smooth thence to 

 the apex. Spire conoid, apex flat and rounded. Whorls 4|, flat, the last mo- 



* Since this paper was written, the sad news has reached us that this liighly gifted 

 naturalist — to whom all readers of this Journal and I personally owe so deep a debt of 

 gratitude, and who to many of us was a dear and cherished friend — had succumbed to 

 the exposure when in Yarkund and on his return journey to Leh. It may be truly said of 

 Stoliczka that he gave his life to the very last, and died nobly in the pursuit of Science.
