Ilab. Ceylon. 



Tlie species grouped together in this Plate partake 

 largely of the characters of Ci/therea, and may be referretl 

 to either genus. This and T. phiyida are especially con- 

 nected with Bioiie and Cythurea ,■ but, as being arranged 

 in iMr. Cuming's collection by Mr. Sowerby under Tupes, 

 I have nut thought it worth while to displace them.

Hub. Australia ; Strange. 



A smooth shell, of a smoky fulvous or ash-grey colour, 

 delicately carved with concentric lines down the posterior 

 margin. Mr. Sowerby refers this shell to Venus, but it 

 partakes more of the character of Tapes than the preceding 

 species.
