EMENDATIONS TO THE MONOGRAPHS OF 

 VENERID^. 



The Editor is indebted for nearly all the following observations 

 to his friends M. Deshayes and Mr. Hanley, who also kindly 

 favoured him with some others, which he is not quite prepared 

 to adopt. M. Deshayes has described some new species in the 

 ' Zoological Proceedings^ and in the ' British Museum Catalogue •/ 

 but the preparations for the present number were too far advanced 

 to admit of their insertion. 



Cytheils;a. 



C. innocens, pi. clxiii. f. 210. 



C. disrupta, pi. clxiii. f. 208, 209. 



C. multistriata, pi. cxxxvi. f. 177. 



I have little doubt but these are varieties of the same species, 



which has been previously described by Mr. Hanley as C. 



Guneri. 



C. spathulata, comes from China. 



C. Sinensis should be numbered in Plate cxxxi. 80 and 81, in- 

 stead of 79, 80. The right-hand top corner figure should 

 be 81. 



C. Tellinoidea (76) was previously described by Mr. Hanley as 

 C. cor. 



C. Kingii, ") M. Deshayes is decidedly of opinion that these 

 C. Lamarckii J species are identical. 



C. corbicula is the Mactroides of Born. 



C. Mactroides is now named Dillwinii by Deshayes. 



C. nitidula (14) is not the true species of Lamarck, but M. 

 Deshayes has named it C. Delessertii. 



C. dnUa (2) is considered by M. Deshayes to be a variety of C. 

 crassatelloides. 



C. elegans (113) was previously named C.pulchra by M. Deshayes. 



C. elUptica (114) should be included in C. calypiga, no. 112. 



C. striata (87) is tmnens, Gmel. 



With regard to the difficult identification of C. lusoria, C. im- 

 pudica, C. meretrix, C. formosa, and several other species, M.
