556 ATr. A. Tlcnipel on Brazilian Cocculfie. 



cliaractcristic is the delicato pale pink blotching round the 

 margins, both ventral and anterior, internally; the pallial 

 sinus is large, extending almost to the centre of the interior. 



A specimen identical with those from Aden has been 

 dredged off the Mekran coast of Baluchistan, not very far 

 from Karachi, by ]\Ir. F. W. Townsend, and I purpose 

 figuring this, as it is so much the largest, in company with 

 one of Commander Shopland's types. 



It is important that no contusion should exist between 

 Cuviingia (amellosa, Sowh., 1833, from Chili, and C. {Thyella) 

 himeUosa, H. Ad. {= Cuming I'a elegans, Sowb.), from the 

 Eastern Archipelago and Australia. In this latter the lateral 

 teeth are absent in either valve.

 So). — It is necessary to refigure this, the former delinealioir 

 not having been very successful. This species has since been 

 found by 31r. Townsend near Bushire and Maskat.
