SCI^NID^. IO3 



An abundant species in Lake Erie, ascending the larger tribu- 

 taries to some distance. The species is said to be common in the 

 lower Ohio, but no one seems to have noticed it within the limits 

 of the state, though it probably ascends to that distance. Lake 

 Erie, Henshall, 1889; Lorain County, "quite common in the 

 lake, ascending the streams to the dams," McCormick, 1892 ; 

 Maumee river at Grand Rapids, Waterville and Toledo, Kirsch, 

 1893 ; abundant in Lake Erie at Sandusky, rare in Huron river 

 at Milan, R. C. Osburn, 1899.

 the Ohio river form as 5*. grisea, Jordan gives it as very abund- 

 ant in Lake Erie, and also mentions it for the Ohio. Hamilton
