Hob. Tanir Eidge, Dafla Hills, K of' Assam, also Hengdan 

 Peak, North Cachar Hills S. of the Assam valley ( Godwin- Austen). 

 Distinguished by its well-marked costulation. 



408. Zaliella subcostulata, Godwin-Austen. Mol Ind. i, 1882, p. 8, 

 pi. 2, fig. 6 (shell). 



This is very near costulata, but the ribbing is not quite so 

 regular or so strong, the concentric striation on the base is more 

 distant, the shell is smaller, the whorls are convex, and the suture 

 well impressed. 



Diam. 2|, height 2 mm. 



Hob. North Khasi Hills. 



*409. Kaliella salicensis, Godwin-Austen, Proc. Mai. Soc. ii, 1897, 

 p. 178, pi. 14, fig. 3 (shell). 



" Shell perforate, conical ; sculpture irregular, coarse, transverse 

 ribbing; periostracum umber-coloured ; spire conic, flat-sided, suture 

 very shallow ; whorls 7, sides rather flat ; aperture quadrate, 

 straight below ; peristome suboblique, columellar margin reflected. 



"Size: major diam. 2-8 ; alt. 3." (Godwin-Austen.) 



Hob. Uda Pussalawa, Ceylon (H. B. Preston). 



" The whorls of this species do not increase in breadth so much 

 as in K. larrakporensis ; the fine regular transverse sculpture is 

 absent, rougher irregular ribs taking its place. The base of the 

 Ceylon shell is not so broad, in proportion to the height of the 

 spire, as in the Bengal species." 



This is of much the same shape as K. barrakporensis ; the last 

 whorl is sharply keeled. 



b. Height much exceeding diameter.

 1878, p. 41; Godwin-Austen, Mol. Ind. i, 1882, p. 6, pi. 1, 

 fig. 12 (shell). 



Shell subperforate (subobtectly perforate), pyramidal, elevately 

 conical, thin, scarcely striated, smooth, not polished, translucent, 

 brownish horny ; spire high, conical, sides almost straight, apex 

 obtuse, suture shallow ; whorls 7, slightly convex, the last keeled, 

 but not sharply ; aperture nearly vertical, semicircularly lunate ; 

 peristome thin, straight, columellar margin vertical, reflected, 

 concealing the perforation. 



Diam. 2, length 3 mm. 



Hob. Nilgiri Hills, Pykara. 



This is near K . fastigiata, but smaller, and higher in proportion, 

 to the diameter.
