BIOLOGICAL SOCIETY OF WASHINGTON ^'^^O^i^' A LIST OF THE FISHES OF PENNSYLVANIA. 6 BY HENRY W. FOWLER. i The present paper is a summary of the data accumulated during the past twenty years, presented in condensed form, so that the distribution of each species may be traced so far as present details permit. For this reason they are arranged ac- cording to the various hydrographic basins with only the counties mentioned, additional records, where noteworthy, being supplied in parentheses. The work is therefore intended as a slight contribution to the distribution of our local fishes. Like many departments of natural history the founding of the binomial system by Carl von Linne in 1758 first establishes several fishes from Philadelphia. Alexander Wilson contributes the first notice of shad and alewife in the article on ichthyology in Ree's Encyclopaedia, to which he secured an assistant editor- ship in 1806. His article was published about 1812. Charles Alexandre Le Sueur is the first to carefully study the fishes of this State, much of his material doubtless having been secured near Philadelphia. He is credited with sixteen of our species, while eight other names he proposes are synonyms. Con- stantine Samuel Rafinesque described many of our species in his Ichtlyologia Ohiensis. The localities given are seldom definite and usually would apply to the entire Ohio basin. He has described twenty-three of our species, besides fourteen synonyms. Several of our species are also described by Achille Valen- ciennes, in colaboration with Baron Cuvier, in the great Histoire Naturelle des Poissons. Samuel Stehman Haldeman studied the fauna of the lower Susquehanna, though his contributions to ichthyology are rather incidental. He was signally unfortunate 1 Published by permission of the Academy of Natural Sciences of Philadelphia. 14— Phoc. Biol. Soc. Wash., Vol. 32, 1919, (49) 50 Proceedings of the Biological Society of Washington. 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.

Le Sueur's type' is stUl in the Academy and agrees with several examples I examined in the field. Scaphirhynchus platorynchus (Rafinesque). Shovel-nosed Sturgeon. Though the late Dr. Bean mentions^ that "in the large tributaries of the Ohio, in western Pennsylvania, the species is very common," the original account by Rafinesque^ contains our only definite record.

Originally described from the Ohio at Pittsburgh,' though no recent records given. I found it at Erie. DOROSOMIDiE. Dorosoma cepedianum (Le Sueur). Mud-shad. Only recorded from the tidal of the Delaware basin, (Andalusia) Bucks, Chester, Delaware and (Bridesburg, Tacony) Philadelphia Counties. Le Sueur originally^ obtained it in the "market of Philadelphia." CLUPEIDiE. Pomolobus chrysochloris Rafinesque. Inland Alewife. Known from Rafinesque's original account,^ which gives it from the Ohio River and also says "it seldom goes as far as Pittsburgh." "Herring" re- ported formerly in (the Conemaugh River) Indiana County were likely this species. Pomolobus mediocris (Mitchill). Fall Herring. I have no local material though include this species provisionally, or only on reports of its occurrence in the Delaware River tidal of Bucks County at Tullytown. In late October, 1906, a school of about fifty large examples were reported at this point. When swimming at the surface they produced quite a disturbance, somewhat like a school of menhaden. About eight were taken on hooks baited with our common river killifishes {Fim- dulus), which were fastened to the hook by the upper jaw. When opened the herring were found more or less gorged with killifish. They took the bait with a rush and greatly interested the local anglers who called them "jacks" or "skipjacks." They remained until November. A large herring taken at the same place in December, 1912, was doubtless the same species. Pomolobus pseudoharengus (Wilson). Alewife. Delaware basin, (New Hope) Bucks, Delaware and Philadelphia Counties. Susquehanna basin, (Harrisburg) Dauphin, (reported at Clarke's Ferry dam in North Branch'*) Lackawanna, (Bainbridge, Fite's Eddy, Marietta, McCaU's Ferry, Pequea, Safe Harbor) Lancaster, (Marysville) Perry and (McCall's Ferry, Peach Bottom and York Furnace) York Counties.

Brevoortia tyrannus (Latrobe). Menhaden. Valenciennes early mentions it as abundant in the markets of New York and Philadelphia, and later Cope says it ascends the Delaware for a short distance in our limits. I have it from the New Jersey shore at Washington Park in August, 1908, and since then small examples have been found in Bucks (far as Dunk's Ferry) and Philadelphia Counties. SALMONIDiE. Coregonus clupeaformis (Mitchill). Whitefish. Abundant at Erie. Leucichthys sisco (Jordan). Sisco. Known from Erie examples reported by Jordan and Evermann.^ Leucichthys artedi (Le Sueur).

Reported from the Monongahela River by Evermann and Bollman.^ Ictalurus punctatus (Rafinesque). Spotted Cat. Ohio basin in Allegheny, Beaver, Clarion, (Blairsville formerly) Indiana and Westmoreland Counties. Erie basin in Erie County. Possibly the alleged A. nigricans (Le Sueur) is not distinct from the present species. The late Dr. Bean says "Erie re- ceives its supply of catfish from fishermen who operate in the lake from Erie to Elk Creek, with set-lines during the summer months." A number of catfish in the markets and fisheries at Erie were examined and all of the fork-tailed forms were the spotted cat. All had the predorsal bony bridge complete and but few were without spots. Ameiurus catus (Linnseus). White Cat. Delaware basin in Bucks, (Brandywine Creek) Chester, Delaware and (League Island) Philadelphia Counties. Susqueharma basin in Lancaster and (Peach Bottom) York Counties. Ameiurus natalis (Le Sueur). Yellow Cat. Only met with by me at Erie. Not found east of the Alleghanies in our limits, though in the Ohio basin early recorded as far as Pittsburgh. ^ Ameiurus nebulosus (Le Sueur). Common Cat.

A single example I obtained in high color July 23, 1899, in McKean County at Cole Grove, is interesting as a new addition to the fauna. ^ It was captured in a small mountain-stream, the surface of which was largely covered with petroleum, so that the fish was not discovered until taken out of the water in a net. Associated were a number of other small fishes as creek chubs, silver-fins and cut-lips.

Cope in the lower Susquehanna, within our limits, is an addition to the State's fauna. No exact locality is given. The specimen is 667 mm. long and still in good preservation. Comparison with Massachusetts and Italian material reveal all its characters in harmony. As the species enters our limits by way of Chesapeake Bay it may occur casually in any of the other large rivers tributary. I have, however, not certainly secured it in the Delaware. ATHERINID^.

Eucalia inconstans (Kirtland). Brook Stickleback. I obtained it in the Allegheny at Foxburg. Gasterosteus aculeatus Linnaeus. Two-spined Stickleback. I have no local material, though it has been recorded from the Delaware at Philadelphia by Dr. C. C. Abbott.' It must be rare or extremely local in our limits, as I never met with it away from the coastal region, or far from salt water. To the contrary the late Dr. Bean says "in Pennsylvania Mr. Seal has found this fish abundant in pools and ditches along the Dela- ware," a statement^ which in every way agrees with my knowledge of Apeltes quadracus. Apeltes quadracus (Mitchill). Three-spined Stickleback. Delaware basin in Bucks, Delaware, Lehigh, Northampton and Phila- delphia Counties. Jordan and Evermann state "male almost black; ventralswith the membrane red in spring," though of the countless spawn- ing examples I have examined never a black male has been seen, and most all the males at every season of the year had red ventrals.

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. iJourn.
