A typical specimen is drawn in fig. 1, 2 of plate 6. The 

 shell is corneous-yellow, very bright and glossy, nearly 

 smooth. The sides of the spire are very slightly convex; 

 but the whorls are strongly convex, parted by a very dis- 

 tinctly crenulated suture. The aperture is small; columella 

 very deeply excavated above. Length 17, diam. 7.8, aper- 

 ture 6.8 mm. ; whorls 7y 2 - Nalande, Ceylon. 



Var. PUNCTOGALLANA (Pfeiffer). PI. 6, figs. 3, 4, 5. 



Shell oblong-ovate, slightly striatulate, glabrous, glossy, 

 pellucid, corneous-tawny. Spire pyramidal, the apex obtuse. 

 Whorls 7y 2 , convex, the last about two-fifths the total length, 

 base rounded. Columella very deeply arcuate, reaching far 

 forward, abruptly truncate. Aperture vertical, subtriangu- 

 lar-semioval ; peristome simple, the right margin regularly 

 arcuate. Length 16, diam. 8, aperture 7x4 mm. (Pfr.).

 Coll.) ; Balapiti (Nevill).

"Differs from A. ceylanica by the smoother, more glossy 

 shell, with longer spire, shorter last whorl, and the columella 

 arched forward more ' (Pfr.). The whorls are much more 

 convex in punctogallana than Pfeiffer 's description and fig- 

 ures indicate in ceylanica. The largest shell before me (fig. 

 5) measures, length 17.5, diam. 8.4, aperture 7 mm., whorls 

 nearly 8. Others from the Matelle district, received from 

 Layard, are typical in size. Both lots were received as 

 ceylanica. 



This form differs from G. nitens by its stouter, more com- 

 pact shape.
