2 This and grossa are certainly very different in aspect from the cygnea, Lam., being more pon- 

 derous and less produced behind. This difference may, however, be effected by locality. Should it 

 prove constant, ponderosa ought to be considered a distinct species, and such may prove to be the fact, 

 but I doubt it much. 



3 I presume that Bosc meant the same variety as JL/t. fluviatilis, Gmel. But he refers to Lister's 

 PI. 15T, which is probably Unio cariosus, Say. Bosc refers to Europe for the habitat of his species, and 

 certainly there is no species in Europe like Lister's figure. 



4 Count Yoldi's letter to me. 



5 He since considers it a variety of cellensis, Pfeif.
