 It has been reported from the Amoor River drainage, but 1 presume 

 tliat the specimens from that region belong to the group of A. woodiana.

' Credited by Rossmassler to Kokeil Museum. 



■^There is an Anodonta rostrata Held in Isis, 1836, page 280. I do not know 

 whether it or that of Rossmassler was published first, or whether the two are the 

 same or not. 



^Probably a valid species, yet some specimens apparently belonging to it are cer- 

 tainly very much like forms of cygnea.
