1 This appears from the figures and description to be a member of the Mgyptiaca 

 group of Nodularia. It is possible that it came from Asia Minor, but more likely 

 that it is an African species. The Unio eucyphus of Bourguignat, which he credits 

 to this region, is believed by Lea to be the U. (egypiiacus of Cailliaud, and I agree 

 with him. Unio hagdadensis may be merely a peculiar form of the same thing. 



^This may possibly be distinct from N. nilotica, or it may only be an oddly- formed 

 specimen. 



^I can not be positive as to the systematic position of this species, but it probably 

 belongs here.
