516 LIEUT.-COL. H. H. GODWIN-AUSTEN ON NEW [June 14, 



A larger shell, with rather a difFerent shaped spire 4 millim. in 

 height, was found at Asalu, with the constriction in same position. 



It is an allied form of D.jatingana, from the North Cachar Hills, 

 which is a larger, more tumid species with the constriction farther 

 behind the aperture. 



A single specimen, only 3 millim. in height, was sorted out of the 

 box containing B. chennelli, from the Lhota Naga Hills. 



Small species, with columella)' process. 



DiPLOMMATINA XJNICRKNATA, U. Sp. 



Loc. Eastern Naga Hills {W. Boherty, in coll. T. H. Aldrich). 



Shell dextral, orately fusiform, subrimate, rather thin ; sculpture, 

 distant strong costulation on all the whorls ; colour white, with a 

 pale lemon-yellow tint in fresh shells ; spire with sides convex, apex 

 somewhat blunt ; suture well impressed ; whorls 7|, antepenultimate 

 the largest, sides convex, the constriction above the aperture, in front; 

 aperture circular, vertical ; peristome double, outer wavy in outline, 

 with one very marked and decided crenulation on the upper outer 

 margin, and a shght sinuation on the left lower margin ; columellar 

 tooth large and directed downwards. 



Size: alt. axis 4-0 millim. 



A very large number of this new shell are in Mr. Doherty's collec- 

 tion, four from Margarita in a tube, the remainder marked as from 

 the Naga Hills. This is a very beautiful new species, the only shell 

 approaching it that I know from this region being B. angulata of 

 Moulmain. 



DiPLOMMATINA JAPVOENSIS, n. Sp. 



Loc. Japvo Peak, Anghami Naga Hills, 10,000 ft. (Godtcin- 

 Austeri). 



Shell dextral, fusiform, thin texture ; sculpture, close rather fine 

 ribbing ; colour pale ochraceous ; spire conic, apex blunt ; suture 

 moderately impressed ; whorls 7h, sides convex, swollen below 

 constriction in front, towards the outer margin of the peristome 

 aperture oval, vertical ; columellar tooth fairly developed, blunt 

 peristome closely double, of weak structure. 



Size : maj. diam. 2'A ; alt. axis 3'8 millim. 



This is larger than the other species from this peak and elevation ; 

 and is the species described as B. sherfaiensis, var., J. A. S. B. 1875, 

 p. 9, pi. iv. fig. 5 ; but as it is sufficiently distinct from the form found 

 on Sherfaisip Peak, far to the west, and also from another fotmd on 

 Shiroifurar Peak, I think it better to give it a distinctive title. 



DiPLOMMATINA ANIMULA, U. sp. 



Loc. Prowi, Lahupa Naga Hills, Munipur {Godiuin-Austen). 



Shell dextral, ovately fusiform, thin and delicate, and glassy 

 texture ; sculpture, rather distant well-marked costulation ; colour 

 whitish grey ; spire moderately high, sides convex, apex blunt ; 

 suture impressed ; whorls 6, tumid, sides very convex, antepenultimate
