"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. 



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

 tainly very much like forms of cyynea.
