^ Lea and Ferussac both referred this to littoralis after examining Lamarck's shells. 

 I have seen specimens in the collection of the former from the Jardin des Plantes, 

 Paris, which are, no doubt, authentic, and which, I think, perhaps, are specifically 

 difi^erent from littoralis, being much shorter and more rounded. 



-A specimen of this in the U. S. National Museum collection, from Tristram, labeled 

 as above, is the same as Lea's examples of semirugattis. 



^Published as Unio maris-galiUn in list in Comptes Eeudus, XCI, p. 502; but not 

 described. 



■'Some of these approach very close to specimens of U. littoralis, especially to the 

 form called U. rothi Bourguignat, which I have placed in that species, and I should 

 not be surprised if there was an absolute connection between the short, rounded 

 forms of U. semirugaius and the longer rhomboid U. littoralis.
