1 Knster figures two species, I think, for gassiest. His fig. 3 is, I think, a young 

 molinw Kuster; fig. 4 seems to equal auratus of Reeve, not of Philippi or Sowerby. 



2 Swainson .manuscript according to Reeve. 



^Not U. auratus of Reeve, figured previously in tha same work. 



■i Credited to Charpentier manuscript by Kuster. See footnote on Diplodon leai 

 Simpson, p. 876. 



^Not Unio {Niaa) atrata Swainsou, which equals Unio gracilis Barnes. Sowerby's 

 name has precedence.
