XIII. — JSfotes on specimens of Corhiculadce in the Cabinet 



of the Jardin des Plantes at Paris, and. on the 



authorship of the Encycloptedie Mcthodique,

I had the opportunity, in 1871, of making notes on some 

 of the Corbiculadm in the Jardin des Plantes, which I am

 with the shell which I published! 

 under the name of Corb iciila 

 Japonica. — Lamarck's species is 

 represented as coming from China, 

 mine is a native of Japan. 



Corbicula Japonica. i • i 



We cannot, however, decide as 

 yet positive!}^ that the orientalis and the Japonica are identi- 

 cal, for the reason that Lamarck refers to his type as being 

 in his own Cabinet, which is at present at Geneva. 



Cyi'ensa tVBjncata, Lamarck. 



Lamarck in his description! of this fossil species stated 

 that it came from the State of New York. There is one 

 valve of the truncata which evidently l)elongs to the Tertiary ; 

 it is intermediate between antiqua and cuneiformis of Eu- 

 rope .

 fact of this species having been found in N. Y., but think
