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



A larger sbell, with rather a diflPerent shaped spire 4 millim. in 

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



It is an allied form of J), jatingana, from the North Cachar Hills, 

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

 hehind. the aperture. 



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

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



Small species, with columellar process. 



DiPLOMMATINA UNICRENATA, n. Sp. 



Loc. Eastern Naga Hills (W. Doherty, in coll. T. H. Aldrich). 



Shell dextral, ovately 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 slight 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 D. angulata of 

 Moulmain. 



DiPLOMMATINA JAPVOENSIS, U. Sp. 



Loc. Japvo Peak, Anghami Naga Hills, 10,000 ft. {Godwin- 

 Austen). 



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

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

 moderately impressed ; whorls 7j, 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*4 ; alt. axis 3*8 millim. 



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

 and is the species described as D. 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 found on 

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



DiPLOMMATINA ANIMULA, U. Sp. 



Loc. Prowi, Lahupa Naga Hills, Munipur (Godwin-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
