Having figured only the large Mediterranean form of

 Venus cequilaiera, Sowerby, jun. 



Hub. Japan. 



This species when catalogued in the TankervUle collec- 

 tion, was referred by Mr. Sowerby, with a note of doubt, 

 to the Venus dunacina of Chemnitz, figured below it in 

 the accompanying plate. 



Species 93. (Mus. Cuming.) 



Venus Peronii. l^en. testa ovoio-cuneiformi, latere an-

Peron's Venus. Shell ovately wedge-shaped, anterior 

 side very short, rather veutricose, fulvous, linearly 

 reticulated with grey, concentrically ridged, ridges 

 close-set, flatly obtuse. 



Lamarck, Anim. sans vert. vol. vi. p. 31)9. 



Hab. Australia. 



Of the same peculiar type as /'. Aphrodinoides, but 

 more ovate and gibbous, with the concentric ridges al- 

 most obsolete. 



Species 94. (Mus. Cuming.) 



Venus strigosa. Ven. lestd ovato-cuneiformi, postici; 

 subattenuatd,fuhescente-spadiced, concentrice liratd et

As intimated by M. Deshayes, this may prove to be a 

 ridged variety of V. AqiUrodina.
