of the Jardin des Plantes at Paris, and on the 



authorship of the Encyclopedia MetJiodique.

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

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

 induced to publish in the hope that their perusal may lead to 

 the correction of some errors prevalent in regard to the 

 species of this family. 



Cyrena orient alls, LAMARCK. 



This species, described in 1818*, is represented by a 

 single valve, which I found to agree 

 with the shell which I publishedf 

 under the name of Corbicula 

 Japonica. Lamarck's species is 

 represented as coming from China, 

 mine is a native of Japan. 



Corbicula Japonica. T _ r . .. . 1 



We cannot, however, decide as 



yet positively 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. 



Cyrena truncata, 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 belongs to the Tertiary ; 

 it is intermediate between antiqua and cuneiformis of Eu- 

 rope. 



As already stated on a previous occasion I doubt the 

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