 sider as doubtful :

 dinarius, Speng. (marginalis, Lam.) from Tranquebar. 



Yilla. A letter of March 10, 1870, from Sig. Villa, Milan, asks my decision on a Unio Danelli described 

 by him, from Melbourne, Australia, but I have not had the advantage of seeing the shell, nor of 

 receiving the description which he sent to me.
