1 Swainson gave the name I'nio truncatus to this species in 1829, but that name, had 

 been applied to a Unio by Spongier in 1793. Bourguignat credits this to Fernssac 

 manuscript under the name of Unio tigrix. 



2 Lea credits this to Fernssac manuscript in museum at Paris. No description has 

 ever been published, so far as I know, though several authors liave cited it and cred- 

 ited it to Ferussac. A specimen in the Lea collection which is no doubt authentic is 

 apparently a delicate young ligridis. 



3 Young shells, and it is very hard to say whether they :ire tigr'ulis or terminaUn.
