353. Sitala? subnaiia, Godwiti-Austen {Xevill, MS.), Mol. Lid. i, 

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



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 

 obhque, semiluuate; peristome thin, columellar margin slightly 

 oblique and reflected. 



Diam. 2|, height 1| mm. 



Hab. Jessore in Bengal. 



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



35-i. Sitala? crenicincta, Godwin- Austen, Mol Ltd. i, 1883, p. 75, 

 pi. 13, flg. 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 belo\^-, 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 periphei^ ; 

 aperture oblique, semiovately lunate ; peristome thin, columellar 

 margin vertical. 



Diam. 2-25, height 1-b mva. A larger variety from 3Iairang 

 measures 2*7 by 1-75 mm. 



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

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

 large, tricuspid, pointed, broad and long ; the admedian 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 . 2b. A variety, slightly 

 larger and very narrowdv perforate, from wood at Mairaug, Ivhasi 

 Hills.]

The close impressed lines give the idea of raised ribs between 

 them, especially on the upper whorls.

 rather close, slightly wavy, impressed lines above and below, only 

 visible under a microscope, crossed by fine oblique striae of growth, 

 brownish horny ; spire conical, suture impressed ; whorls 5|, 

 slightly convex, the last angulate at the periphery, moderately 

 convex beneath, the angulation disappearing near the mouth ;
