simple. The sides of the spire are slightly convex. Pig. 6 

 represents a typical example, length 11, diam. 5.2, aperture 

 4.5 mm., whorls 6%. The lip is "finished." 



Two specimens, the longest and shortest from another lot 

 of 15, are drawn, pi. 6, figs. 12, 13. Neither has the lip 

 "finished," though no doubt both are nearly mature. They 

 measure as follows. 



Length 12.8, diam. 6 mm., whorls l^/\. 



Length 10, diam. 5 mm., whorls 6 1 /-.. 



8. G. PACHYCHEILA (Benson). 



Shell ovate-oblong, striatulate, under a lens decussated 

 with obsolete, close, spiral very fine striae; glossy, brownish- 

 corneous, translucent; spire lengthened, subconic, apex ob- 

 tuse, suture lightly impressed. Whorls 6, a trifle convex, 

 the last scarcely two-fifths the total length. Aperture ver- 

 tical, oblong-ovate ; peristome whitish-bordered within ; colu- 

 mella exceedingly deeply arcuate, basal margin thickened. 

 Length 11, diam. 5 mm. (Bens.).

"This little species of a group which has so many rep- 

 resentatives in Ceylon, the Nilgherries, and the damp woody 

 mountains of the North-eastern India, with a more slender 

 form than A. areas nobis, is well distinguished from the 

 allied forms by its peculiar sculpture under the lens, and by 

 the internal incrassation of the peristome, a feature which 

 is also observable in the species A. crassilabris nobis, from 

 north-eastern India." (Benson.} 



This species has not been figured. With the same dimen- 

 sions as G. deshayesi, it seems to differ by having the whorls 

 only very little convex, whilst in deshayesi they are strongly 

 convex.
