Original descrijjtion : — "Shell sinistral, elongately ovate, rather 

 tumid, sub-rimate, rich amber colour, sharply very regularly and 

 distantly costulated, rather solid ; spire conical, slightly convex ; 

 whorls 5^, sides convex, suture deej), penultimate whorl largest, 

 last whorl strongly constricted in front of the aperture, rising 

 very sli^-litly behind the peristome, chielly between the inner and 

 outer peristome ; aperture slightly oblique, sub-circular ; peristome 

 double, inner slightly expanded, scarcely thickened, terminating 

 in a sinuation at tlie base of the columella ; outer greatly pro- 

 duced, expanded, continuous ;_ parietal callus thin moderately 

 extended ; columellar tooth blunt, moderately developed. 



" Heif^ht 2-j mm., diameter 1^ mm., diameter of aperture with 

 peristome, f mm." 



Eah. India : near Jawai, Jaintia Hills, 4500 ft. ; AVest Khasi 

 Hills {Godwin- Austen). 



"This species is very near I), (jihhosa, from the same region, 

 and thus aftbrdiug a second instance of a type intermediate 

 between the destral forms D. iiaeliycheilus, D. diphcheilus, etc., 

 and the sinistral forms from the Solomon Isles, etc. It is 

 distinguished readily from D. yihhosa by its more regularly ovate 

 form, its costulation, and the even, uon-sinuated margin of the 

 inner peristome. 



" Since the transmission of specimens of Diplommatina, pub- 

 lished in the Journal for 18(58, to Mr. W. Blanford, I have been 

 fortunate enough to discover this species again. As the above 

 quoted figure, on pi. iii, of the " Contributions to Indian 

 Malacology, no. ix," was taken from a single shell, subsequently 

 broken, the species remained unfortunately unnamed and un- 

 described." {Godivin- Austen.)
