1 Lea and Ferussac both referred this to Uttoralin 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 

 different from littoralin, being much shorter and more rounded. 



2 A specimen of this in the IT. S. National Museum collection, from Tristram, labeled 

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



3 Published as Unio maris-yalilcei in list in Comptes Rendus, XCI, p. 502; but not 

 described. 



4 Some of these approach very close to specimens of 17". littoralis, especially to the 

 form called U. rothi Bourguiguat, 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. semirugatua and the longer rhomboid U. littoralis.
