KA.LIELLA. 261 



The specimen measured above, from Teria Grhat, is rather large ; 

 other shells are about 2'5 to 2-7 mm. in diameter. This form is 

 distinguished from K. barrakporensis by a somewhat higher spire, 

 more convex at the sides.

pi. 1, figs. 9, 9 a (shell and sculpture), 10 (var.) ; pi. 2, fig. 3 

 (shell). 



Shell subperf orate, high trochiform, slightly polished, closely 

 and obliquely ornamented under the microscope with raised striae, 

 on the base decussated with very minute concentric strias and 

 radiating lines, brownish ; spire high, conoidal, sides convex, apex 

 obtuse, suture impressed ; whorls 6 J, convex, the last sharply 

 carinate, base slightly tumid; aperture slightly oblique, almost 

 semicircular, columellar margin well reflected, vertical above. 



Diam. 2|, height 3 mm. 



Hob. Manipur Hills and Phunggam, Lahupa Naga Hills, 5000 

 ft. (Godwin- Austen). 



The form from the Naga Hills is a little smaller, with 5 J whorls. 

 Some shells measure 3 mm. in diameter. 



" This shell differs from the Cherra and Khasi species (K. cher- 

 raensis) in the whorls being more convex, more tumid below, and 

 the columellar margin not so oblique. It is nearest in shape to 

 K. aspirans of Southern India." (Godwin-Austen.} 



406. Kaliella khasiaca, Godwin-Austen, Mol Ind. i, 1882, p. 5. pi. 1, 



fig. 8 (shell). 



Shell imperforate, high trochiform, very closely obliquely ribbed 

 above, smooth on base, brownish horny ; spire conical, sides rather 

 convex : whorls 7|, convex, the last angulate, slightly tumid be- 

 neath ; aperture subquadrately lunate ; peristome thin, columellar 

 margin vertical. 



Diara. 2-25, height 275 mm. 



Hob. North Khasi, common. 



This is distinguished from cherraensis and manipurensis by not 

 having a raised keel at the periphery, by more numerous whorls, 

 and by want of concentric sculpture on base. 



407. Kaliella costulata, Godwin-Amten, Mol. Ind. i. 1882, p. 7, pi. 2, 



fig. 5 (shell). 



Shell imperforate (subperforate), trochiform, thin, translucent, 

 polished, ornamented with oblique distant ribbing, stronger than 

 usual above, and very fine concentric striation beneath, pale horny 

 brown ; spire conical, sides straight, suture scarcely impressed ; 

 whorls 6, rather flat, the last carinate, flatly convex beneath ; 

 aperture slightly oblique, subquadrately lunate ; peristome thin, 

 columellar margin vertical, reflected. 



Diam. 2|, height 3 mm.
