1882, p. 75, pi. 14, tig. 6 (shell). 



Shell subperf orate, conoid, obliquely striated and decussated by 

 fine, rather close, impressed spiral (longitudinal) lines, pale brown ; 

 spire conical, rather low, apex obtuse, suture impressed ; whorls 4|, 

 convex, the last subangulate, flatly convex beneath; aperture 

 oblique, semilunate; peristome thin, columellar margin slightly 

 oblique and reflected. 



Diam. 2^, height 1| mm. 



Hob. Jessore in Bengal. 



A small, low conoid shell, subangulate at the periphery. 



354. Sitala ? crenicincta, Godwin-Austen, Mol Ind. i, 1883, p. 75, 



pi. 13, fig. 2 (shell), p. 145, pi. 38, figs. 4, 4 a (teeth of radula). 



Shell perforate, depressedly turbinate, thin, obliquely striatec 

 and decussated with fine, rather close impressed lines both above 

 and below, brownish horny ; when fresh with two spiral parallel 

 rows of fine hairs ; spire conoidal, apex obtuse, suture well im- 

 pressed ; whorls 4, convex, the last rounded at the periphery ; 

 aperture oblique, semiovately lunate ; peristome thin, columellar 

 margin vertical. 



Diam. 2-25, height 1-5 mm. A larger variety from Mairaug 

 measures 2-7 by 175 mm. 



[The radula is very similar to that of Kaliella barrdkporemU, 

 but the outer laterals are not tricuspid. The centre tooth is very 

 large, tricuspid, pointed, broad and long ; the adrnedian teeth are 

 bicuspid, the outer cusp near the base, while in the outermost 

 3 or 4 it nearly disappears. Few teeth in the row. Formula : 

 18 to 20 . 5 . 1 . 5 . 18 to 20, or 25 . 1 . 25. A variety, slightly 

 larger and very narrowly perforate, from wood at Mairang, Xhasi 

 Hills.]

 Teria Ghat, Shillong, &c. (G odium- Austen). 



The close impressed iines give the idea of raised ribs between 

 them, especially on the upper whorls.

 brownish homy ; spire conical, suture impressed ; whorls 5J, 

 slightly convex, the last angulate at the periphery, moderatefy 

 convex beneath, the angulation disappearing near the mouth ;
