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 

 sperrnatophore). 



Shell narrowly umbilicate, depresseclly trochiform, decussated 

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

 centric, the transverse (oblique or radiating) close, the spiral 

 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. lailangfcotensis. 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 differ from those of K. bar- 

 rakporensis. 



444. Kaliella? lailangkotensis, Godwin- Austen, Mol. 2nd. i, 1883, 



p. 68, pi. 15, tig. 1 (shell), pi. 20, figs. 2, 2 (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. 



Hob. Lailangkote, Khasi Hills, common, also at Mairang, Teria 

 Ghat, Maotherichan Peak, and Mokarsa. 



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

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

 lower surface is much more tumid than in that species, mouth 

 broader, &c. 



III. Subturbinate, ivhorls rapidly increasing.

Shell umbilicated, depressedly conoid, sub turbinate, thin, rugately
