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

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



DiPLOMMATiNA JAPVOENSis, Godwin-Aiisten. (Plate LXVI. 

 figs. 11, 11 a.) 



Diplommatina japvoensis^ G.-A. P. Z. S. 1892, p. 516. 



Localitif. Japvo Peak, Anghami Naga Hills, 10,000 ft. (Godivin- 

 Auslen). 



Orif/inal description: — "Shell dextral, fusiform, thin texture; 

 sculpture, close rather fine ribbing ; colour pale ochraceous ; spire 

 conic, apex blunt ; suture moderately impressed ; whorls 7^, 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 mm. 



" This is larger than the other species from this peak and eleva- 

 tion ; 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 a 

 distinctive title." 



Small species^ luith columellar process.

Diplommatina unicrenata, G.-A. P. Z. S. 1892, p. 516. 



Locality. Eastern Naga Hills ( W. Dolierty, in coll. T. H. Aldrich). 



Original dcscripdion : — " Shell dextral, ovately fusiform, sub- 

 rimate, 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 im- 

 pressed ; whorls 7g, 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 sinua-

 downwards. 



" Size: alt. axis 4*0 mm. 



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

 collection, four from Margai-ita 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."
