Ongincd description : — " Shell perforated, couically ovate, tliin, 

 finely striated, light yellowish, with two spiral rows of sub-distant 

 chestnut spots, sub-quadrate in form, on all the whorls, and two 

 spiral chestnut stripes, the lower sometimes very faint, upon the 

 last whorl below the periphery. Spire conical, apex acute, sutures 

 impressed. Whorls og, convex. Aperture nearly oval, slightly 

 oblique. Peristome thin, margins united by a thin callus, colu- 

 mellar margin vertical, narrowly reilexed, the reliexed portion 

 meeting the penultimate whorl at an angle. 



" Length 14, diam. 9 millim. Aperture 7 mill, long, 4^ broad."

" There is some doubt whether the shells above described be 

 adult. They have a somewhat immature appearance, but all the 

 specimens sent, four in number, ai'e of precisely the same size, and 

 the thin peristome is characteristic of the group of Bidimvs 

 Bengalensis, to which the present species belongs. From that 

 species and its allies, it is eas^ily distinguished by its short conical 

 form." {Blanford.) 



Most of the specimens of this species I have seen are larger 

 than the type. Three shells in the British Museum measure 

 19 X 10-5 mm., two in the Theobald collection IS x 10 mm. ; while 

 live specimens in the Beddome collection range from 16x10 to 

 12'.j X 8 mm., the latter being immature. All possess the two 

 narrow, chestnut, spiral infra-peripheral bands and the two supra- 

 peripheral spiral rows of subquadrate spots, referred to in the 

 original diagnosis. 



The species appears to be confined to the Anamullay Hills, as I 

 have neither seen specimens from any other locality nor traced 

 any record of such.
