1 Lauiarck refers this in the Animaux sans Vertdbres first to his Systems An. sans 

 Vertobres, published in 1801, and thirdly to Draparnaud ( I list. Moll. Fr.,1806). Dra- 

 parnaud published this species under the name Unio littoralis without a figure in the 

 Tableau Mollusques de France, 1801, which appeared, according to Moquin-Tandon, 

 about July 1 of that year. I do not know which has priority, but Lamarck refers 

 to u characteristic figure in the Encyclopedic Methodique (17;'7), thus fixing the 

 species without a doubt, and as he is most generally considered its author I shall 

 credit it to him. 



-Fig. 743 is a small I', littoralis. I think 747 is U. batavus. 



3 Only a partial inside view is given of two valves. Scliumacher says it very 

 much resembles U. corrugatus Retzius, but is larger, and the teeth are very different. 

 I believe it is a T. littoralis. 



4 Lamarck refers this species to the Isle of France. Sgan/iu states (Me"rn. Soc. 

 Hist. Nat. Strasb., 1840-46, p. 8) that the amateurs he consulted in that island 

 assured him that no such mollusk was found there. According to Lea it is Unio 

 littoralis.
