Yalyata sincera Say. 



Binney, op. cit., part iii, p. 12. 



Dredged iu great abundance in 8 to 13 fathoms, among Gladophora, on 

 the south side of Saint Ignace ; in 4 to 6 fathoms in the cove at the east- 

 ern end of the same island ; in 6 to 8 fathoms among the Slate Islands ; 

 and in 13 to 15 fathoms at Simmon's Harbor j also with the last species 

 from stomachs of white-fish and sturgeon.

 Amnicola pallida Haldeman (?). 



Binney, op. cit., part iii, p. 83. 



An Amnicola, found in great abundance in the stomach of white-fish 

 taken at Sault Sainte Marie, is doubtfully identified with this species by 

 Mr, Wheatley. 



Amnicola limosa Say, (Binney, op. cit., part iii, p. 84,) probably occurs 

 in Lake Superior, although I do not find it recorded from the lake. 



Amnicola granum Say.

 occurs in Lake Superior, since it ranges north to Lake Winnipeg -and 

 Great Slave Lake.
