'■'■ Ilab. in insula Ceylon (Thwaites)." 



Specimens in formalin were sent me by Mr. 0. Collett from 

 Ambagamuwa, Ceylon. 



The animal is pale-coloured ; length of foot shrunk up to 5 mm. ; 

 the dorsal lobes are quite black, and a patch of the same colour is 

 conspicuous on both sides of the neck and near extremity of the 

 foot ; the pallial margin is broad, the integument covering the 

 branchial chamber is black with some white patches (when the 

 shell is removed it is at once apparent) ; the mantle-zone has no 

 shell-lobes. 



The jaw has a slight central projection. 



* While these pages were passing through the press another specimen of 

 this species was received ainoug a collection of shells kindly sent me lor deter- 

 mination by Mr.N. Anuandale from the Calcutta Museum.
