for it is not probable that Dr. Leith himself collected in Ceylon, 

 and the shell does not resemble other Ceylonese or S. Indian forms.

p. 69, pi. 15, figs. 3, 3 a (shell), p. 146, pi. 40, fig. 10 (radula and 

 spermatophore). 



Shell narrowly umbilicate, depressedly trochlform, decussated 

 above by oblique and spiral ribbing, below by radiating and con- 

 centric, the transverse (oblique or radiating) close, the spii'al 

 more distant, pale horny ; spire conoid, apex obtuse, suture 

 slightly impressed ; whorls 5, flatly convex above, the last sharply 

 keeled, almost flat beneath ; aperture slightly oblique, subtrape- 

 zoidal. angulately lunate ; peristome thin, curved back on right 

 margin, columellar margin very oblique, scarcely reflected. 



Diam. 4-25, height 2*5 mm.

The lingual ribbon which has been extracted from a dried 

 individual closely resembles that of K. lalJanr/l-otensis. The 

 formula is 25 . 6 . 1 . 6 . 25 (31 . 1 , 31) ; rhachidian and admedians 

 tricuspid; laterals bicuspid, with the outer cusp far back, not 

 near the terminal one. The laterals difl'er from those of K. har- 

 ralcporensis .

p. 68, pi. 15, fig. 1 (shell), pi. :?0, figs. 2, 2 a (jaw and radula). 



Shell narrowly and deeply umbilicated, sublenticular, decussated 

 with transverse and longitudinal ribbing above and below, the 

 concentric (longitudinal) sculpture disappearing near the umbilicus, 

 pale brownish ; spire low, conoidal, sides convex, suture impressed ; 

 whorls 5, convex, the last angulate at periphery, convex below ; 

 aperture slightly oblique, angulately lunate; peristome thin, 

 columellar margin oblique. 



Diam. 4*3, height 2-3 mm.

The lingual ribbon is very similar to that of K. Jcezamahensis, 

 and the formula is 26 . 2 . 5 . 1 . 5 . 2 . 26 (33 . 1 . 33). The 

 lo\Aer surface is much more tumid than in that species, mouth 

 broader, &c.
