Haldeman described it as Perca nebulosa from the Susquehanna.' At the 

 same time he also described Perca minima from the same stream, though 

 not the young as he suggests, but simply a tessellated darter. He also 

 gave the manuscript name Percina himaculata to Storer for still another 

 example from the Susquehanna several years later, ^ this insuring the 

 generic name for the log perches. The types of the first two nominal 

 forms I have examined. Cope overlooks' the occurrence of the log perch 

 in the Susquehanna, as he only mentions it from Lake Erie and the Alle- 

 gheny River.
