'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. mardinensis. As 

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

 I am compelled to change its name. 



2 Lamarck's brief description of Anodonta nniopsls entirely agrees with the shell 

 commonly known as Microcondyla>a or Monocondyla-a 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 worthy of a varietal name.

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