'Locard described this as a Pseudodon, and previously in the same year described 

 a Leguminaia chantrei, which seems to me to be a mere variety of L. niardinensis. As 

 both are undoubtedly Leguniinaias, and as the present species was the last described, 

 I am compelled to change its name. 



-Lamarck's brief description of Anodonta uniopsis entirely agrees with the shell 

 commonly known as Microcondyla'a or Monocondylwa bonelli. The statement that the 

 ligament passes into the hinge exactly fits this, and this is one of the best generic 

 characters of Leguminaia. 



■'The amount of variation of this species is very great. In many cases the poste- 

 rior end has evidently been injured by unfavorable environment, and the shell is 

 dwarfed and variously distorted, and sometimes a good deal thickened. Of course 

 every individual variation and distortion of this kind has been seized on by the New 

 School and elevated to specific rank. I have seen only what seemed to me a single 

 species of this subgenus, and nothing which really was worth j^ of a varietal name.

 Ferussac's manuscript labels, neither of which constitutes a published description.
