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



DiPLOMMATINA TUMIDA, var. 



Loc. Laisen Peak and Trigonometrical Station, Munipur. 



Shell dextral, elongately fusiform, not rimate; sculpture, fine costu- 

 lation on the 5 apical whorls, the last smooth ; colour pale greenish ; 

 spire with convex sides, apex acuminate ; suture well impressed ; 

 whorls 7^, penultimate and antepenultimate equal ; constriction above 

 the aperture, but towards the right-band side ; aperture oval, vertical ; 

 peristome thickened, double ; columellar margin straight and angu- 

 late below, the tooth in front, moderately large. 



Size: maj. diam. 2'4 ; alt. axis 5"0. millim. 



DiPLOMMATINA CHENNELLI, n. sp. 



Loc. Lhota Naga Hills {Chennell). 



Shell dextral, of solid form ; sculpture, very fine, rather distinct 

 ribbing, with scarcely any relief ; colour pale ochraceous and sienna- 

 brown ; spire flat-sided, apex acuminate ; suture rather shallow ; 

 whorls 8| to 9, sides flatly convex, constriction in front, the last 

 two whorls equal in size ; aperture oval, vertical ; peristome thickened, 

 strong ; the columellar margin vertical and angulace below. 



Size: (1st sp.) maj. diam. 2'9 ; alt. axis 5-9 millim. 



Size: (2nd sp.) maj. diam. 2'9 ; alt. axis .')"0 millim. 



This has close affinities to D. labiosa from the Khasi and Garo 

 Hills ; but, although far larger (nearly double), the columellar tooth 

 is much smaller, the spire more attenuate, and the general shape 

 difi^ers. I name it after the late Mr. A. Chennell, an Assistant in 

 the Indian Survey Department. 



DiPLOMMATINA BUTLERI, U. Sp. 



Loc. Laisen Peak, Munipur {Godwin-Austen). 



Shell dextral, tumidly fusiform ; sculpture, none on the last 3 whorls, 

 very distant, strong costulation on all above ; colour pale sienna- 

 brown, fresh shells glassy and polished ; spire conic, rapidly diminish- 

 ing, apex small ; suture well impressed ; whorls 7|, penultimate and 

 antepenultimate about equal, sides very convex, constriction above 

 the aperture ; aperture nearly circular, vertical ; peristome double, 

 strong, continuous ; columellar margin vertical, angulate below, 

 the tooth large, in front. 



Size : maj. diam. 2'0 ; alt. axis 4*4 millim. 



Six specimens were obtained, together with those of .D. tumida, var., 

 previously alluded to. This well-marked species was also found by 

 me at Prowi, in the Lahupa Naga Hills, at the head of the Lanier 

 River, which drains into the Kyengdwen of Burmah, and was 

 abundant there. I have also two specimens from Kezakenomih. 



Two specimens from Klang Sing, Naga Hills, are rather more 

 tumid. 



I name this after Capt. John Butler, who was the Political Agent 

 accompanying the Survey party on our exploring work, and who 

 unfortunately lost his life in an ambuscade laid by a hostile clan, 

 when the Survey work was again being prosecuted further east under
