1 Kuster figures two species, I think, for gassiesi. His fig. 3 is, 1 think, a young 

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



2 Swainson manuscript according to Reeve. 



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



4 Credited to Charpentier manuscript by Kuster. See foot note on Diplodon leai 

 Simpson, p. 876. 



6 Not Unio (Niaa) atrata Swainson, which equals Unio gradlis Barnes. Sowerby's 

 name has precedence.
