190 Notes on Specimens of the Corbiculadce. 



existed some published record of the same not so widely 

 distributed as the plates of the Encyclopedic, and to clear 

 up my uncertainty I entered into correspondence with M. 

 Crosse the manager of the Journal de Conchy liologie. 



M. Crosse wrote me that to make the information the 

 more authentic he had consulted M. Deshayes, who had been 

 one of the contributors to the Encyclopedic Methodique. 

 M. Deshayes sent him the following, which I have trans- 

 lated. 



"We owe to Bruguiere all the plates of Natural History 

 "of the Encyclopedic Methodique relating to the Fers, 

 "except the last hundred for which we are indebted to Lam- 

 "arck. The names of the -genera printed at the top of the 

 "plates are the only indications which exist relating to these 

 "useful creations, which the author would have placed on 

 "record in text, had not a premature death prevented him 

 "from so doing. With reference to the existing text, Bru- 

 "guiere published one .volume, which ends with the genus 

 "Conus. It was in 1828 that I was entrusted with the fin- 

 ishing of this text; my first volume commences with a sup- 

 plement to the letters a, b, c ; it was published in 1830; 

 "my second volume is of 183-2; so that the text of the 

 "Encyclopedic Methodique" concerning Mollusca is com- 

 " posed of three volumes, one by Bruguiere and two by me."

 Deshayes, Nov. 24th, 1869.)
