in that the four species he described were all anticipated. 

 Charles Girard was a frequent contributor to North American 

 ichthyology, and though he described two species from our 

 limits both are synonyms. Spencer Fullerton Baird published 

 a few notes on Pennsylvania fishes and the only one he described 

 added another synonym to our well known fall-fish. 



The serious study of Pennsylvania fishes, however, begins 

 with Edward Drinker Cope in his elaborate memoir the "Synop- 

 sis of the Cyprinidae of Pennsylvania. "^ Later he attempted 

 "The Fishes of Pennsylvania, "^ intended as a partly popular 

 descriptive catalogue, apparently modeled from Jordan's 

 Manual of Vertebrates. This work, likely valuable at the time 

 of its publication, is chiefly useful for the notes on habits, etc. 

 Cope described fourteen valid species and five synonyms. In 

 this connection mention should be made of Jacob Stauffer, of 

 Lancaster, who discovered two interesting fishes in his region, 

 which were described by Cope. Stauffer's only contribution 

 appears as his list of the fishes of Lancaster County.' This 

 work is often faulty in the obscurity of determinations of many 

 species. For instance, our common white catfish is described no 

 less than three times. Tarleton Hoffman Bean gives a descrip- 

 tive account^ somewhat like Cope's. It is similarly marred by 

 the inclusion of a number of species native to regions adjacent 

 to Pennsylvania, but never actually taken in the State limits. 



Among living writers Evermann and Bollman^ publish an 

 important account of Monongahela River fishes in 1885. « In 

 1902 Ross gives an account of twenty-five Center County 

 fishes,^ largely of an economic nature. His Minytrema melanops, 

 Leuciscus margarita and Hybopsis dissimilis are important addi- 

 tions, and listed without comment or details of satisfactory com- 

 parison they may be dropped.
