Gcmis CAMPTONYX, Bcnsou (typo C. thcuhaldi, 

 Bens.). 



I do not find the genus in Canis and Gorst. ; probably 

 tliey follow Fisclier in uniting the genus to Valenciewiesia, 

 llouss. (very doubtful in my opinion) ; it is rather an allied 

 form to the Bom-bon Lanzla, Jouss. Woodward classed the 

 genus in the Ot'mUncti). 



1. Camptonyx theobaldi, Benson. 



13 Girnar Hills, Kattywur ; coll. W. Theobald, Esq. 



Genus CAMPTOCERAS, Benson (type C. terebra). 



From the recorded habits of this Mollusk, as also from 

 the characters of the shell itself, I feel convinced Camptoceras 

 will prove to be a sinistral form, closely allied to Succinea, 

 not connected at all with Physa, with which it has hitherto 

 been ranked.
