witli close vertical and liorizontiil lines of a greyisli-ycUow colour,

 woven dotli. Spire elongated, conoidal with convex sides, apex 

 obtuse, sutures impressed. Whorls 7, convex, the last about f of 

 the entire length, roundeil beneath. Aperture vertical, truncately 

 semioval, milky within ; peristome slightly thickened, white, right 

 margin sliiihtly shuiate towards the base, columella deeply curved, 

 obliquely truncated beneath, margins united by a thin callus. 



"Length 26, diam. 13 millim. Aperture 10\ mill, long,

Hah. India : Ananuillay Hills, 6000 ft. {Beddome, Stoliczlca) ; 

 Pulney Hills {Fairhanlc) ; Tinnevelly and Travancore Ghats, South 

 Canara {Beddome); Mahableshwar (Peile). 



" This is the only indigenous Indian Acliatina with which I am 

 acquainted, possessing coloured markings. In form it approaches 

 some of the Ceylon AcJiatince, and also an undescribed Deccan 

 species." (Blanford.) 



" Varies in diameter from 10 to 14 mm. I have specimens 

 from the Tinnevelly Grhats in which the textile colouring is reduced 

 to a single narrow band on each of the thi-ee lower whorls, or is 

 entirely obsolete."' (Beddome.) 



The species is variously ornamented with dark spiral bands and 

 lines, but occasionally specimens occur without either. One shell 

 from South Canara, in the Beddome collection, exhibits some 

 indistinct spiral lines and in addition some opaque transverse lines. 

 Another shell from the Pulney Hills, in the same collection, 

 measures : length 30 mm., diameter 13-5 mm., while two speci- 

 mens from Tinnevelly are dark fuscous, without bands but with a 

 narrow pale sublateral zone; they consist of 6^ whorls and 

 measure 25-5 x 14 mm.
