MOLLUSCA. OF INDIA. 401 



very slight swelling ; aperture oval, subangiilato above ; peristome 

 solid and double on the outer margin, and well reflected but very- 

 thin on the cohimellar side. 



Size : maj. diam. 4'5 ; alt. axis 2*2 mm. 



This is the species which I included in my description of A. in- 

 Jlatus from Japvo Peak in the Anghami-jSTaga Hills. It is an 

 allied form, and on closer examination I consider should receive a 

 name, as it is something more than a variety. Comparison of the 

 figures shows this better than description. 



Alyc^us strigatus, G.-A. 



Of this species obtained by Ferd. Stoliczka in Assam — the exact 

 locality unknown — a single specimen was found at Neuglo near 

 Asalu, North Cachar (No. 2770 B.M. Coll.). 



Altcjetts tanghali, n. sp. (Plate CXXXVIT. figs. 3, 3 a, 3 h.) 

 No. 2671 B.M. 



Loaditj/. Munipur. Exact locality not recorded ; somewhere on 

 the northern side of the valley. 



Shell globoselj turbinate, umbilicus small ; sculpture : close, 

 rather strong costulation where sutural tube begins, gradually 

 getting more distant towards the end, then becoming distant and 

 well marked ; colour whitish, some covered with an earthy deposit; 

 spire conical, rather high ; suture impressed, the sutural tube very 

 long ; whorls 4, the last with very slight constriction in front of 

 sutural tube and slightly swelling forward towards the aperture ; 

 a|)erture nearlj' circular, somewhat angulate above ; peristome 

 double, protruding forward on the sutural margin, the inner slightly 

 reflected ; coluinellar margin rounded. 



Size: maj. diam. 3'5 : alt. axis 2-0 mm. 



I had thought this species to be A. sculptilis, Bs., until compared 

 with that Burmese species. It is of quite a different shape, sculp- 

 tilis being subangulate on the periphery and with a shorter sutural 

 tube. I name it after Tanghal Major, of the Manipur Army, who 

 represented the Eaja when we were laying down the boundary 

 between his territory and the Naga Hills in 1873. 



Altc^tjs theobaldi, W. Blf., var. dituhgensis, G.-A. (Plate 

 CXXXVIII. fig. 4.) 



Locality. Diyung Valley, north of Asalu, N. Cachar (No. 2546 

 B.M.) {Godwin- Austen). 



Shell well umbilicated, depressedly turbinate ; sculpture : rather 

 strong, regular, close costulation extending just beyond the end of 

 the suture, the rest of shell smooth, finely striate, with very distant 

 costulation; colour ochraceous, some with a green tint; spire 

 conic, depressed ; suture well impressed, the tube moderately long; 

 whorls 4, rounded ; aperture circular, slightly angulate above ; 

 peristome double, the outer, viewed from above, rather expanded ; 

 columellar margin rounded.
