1869. J Contributions to Indian Malacology. 143 



The sculpture is peculiar. But a single specimen has been obtained 

 by Major Beddome. 



Oyclophorus ravidus, Bens., has been found by Major Beddome 

 on the Anamullay hills, and in the Wynaad. In both localities it 

 attains a considerably larger size than the type. The Annamullay form 

 is 27 mellimeters by 22, that from the Wynaad, 24 mill, by 191. 

 The operculum, when in good condition, has raised margins to the 

 whorls. I am inclined to consider the species identical with the 

 Ceylon C. annulatus, Troschel. 



Auricula nitidula, described in No. VIII of these contributions, 

 J. A. S. B. Vol. XXXYI, Part II, p. 64, proves to be a variety of 

 A. Gangetica of Benson, with a thicker and darker coloured epider- 

 mis, but not otherwise differing. The dark coloured variety occurs 

 also in the Ganges delta, where it has been found by Dr. Stoliczka.
