'• Tbis little species of a group, wbich has so many representatives 

 iu Ceylon, the ISTilgherries, and the damp woody mountains of 

 North-eastern India, with a more slender form than A. areas. 

 Nobis, is well distinguished from the allied i'orms 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.) 



Jjeddome states that this species and G. deshaycsi, Pfr.. are 

 closely allied, and often confused in collections, but G. i>achyclt.ei}a 

 is a narrower shell than the latter.
