678 AUTHENTIC HISTORY 



tinct species so I have named it, Ichthajlurus Kennskii. Several specimens 

 of blind cat-fish have been taken in the Conestoga, two sent to Prof. Cope, of 

 -which he published a long account in the Proceedings of the Academy of Nat- 

 ural Sciences of Philadelphia, for 18G4, p. 231. Another specimen was taken 

 in November, 1865. This proves to be a new genus and species, named by Prof. 

 Cope, GiiONiAS nigrilabris. The stone cat-fish, distinguished by having the supra 

 occipital separated, tail rounded, confluent with the adipose or second dorsal — 

 known as Noturus marginatus— (also Silurus gyrinus,) concludes this Family. 



Family Salmonid^ — Salmon. 



Fish having an adipose fin and scaly bodies, constitute this family. All the rays 

 of the fins are soft. Our common brook trout is the Salmo fontinalis of Mitchill. 

 These are very variable in color, and may embrace various species. 



Family Clupeid.e — Herring. 



Occasionally caught in the Susquehanna. Tlie green herring is a species which is 

 almost identical with Mitchill's Clupea vernalis; but our Susqviehanna herring have 

 the upper jaw distinctly notched, Cthe distinctive mark of the genus ALOSA,)but it dif- 

 fers in some respects from the Alosa menhaden or moss-bunker, and is more like our 

 Hickory shad, Alosa tyi-annis. The true Susquehanna shad is the Alosa praestabilis. 



Family Sauridje — Gar-pike. 



The common hard-scaled gar of the Susquehanna, is the Lepidosteus osseus. 

 There seem to be several species, or at least distinct varieties. The banded or green 

 Gar belongs to the Esocid^ or Pike family, and is the Belone truncata; also, called 

 Bill-fish. The common pike belongs to the genus Esox. We have variable species; 

 the E. reticulatus and umbrosus. 



Family AxGUiLLiDiE — Eels. 



Anguilla macrocephala, Lesueur, the biill-headed, black or winter eel, also short- 

 nosed eel. 



tenuirostris, the sharp-nosed eel. 



argentea? The silver eel of the fisherman is a variety of this; its white abdomen 

 separated by a lateral line from the color above. 



Family Cyprinid.e. 



Prof. E. D. Coi>e, has published a synopsis of the Cyprinid^ of Pennsylvania, 



■which is full and complete. 



EXOGLOSSUM maxillingua is distinguished by its lobed under lip, a common fish which 

 takes the hook readily. The only species. 



Semotilus rhotheus, the chub or fall fish. The S. corporalis also called chub, has 

 smaller scales, and a dark shade across the eyes. 



Ceratichthys biguttatus, abounds in all the streams in the State, except those enter- 

 ing into the Delaware. It is called the horned chub, from the numerous tuber- 

 cles on the vertex and muzzle. In the breeding season they are often of a lively 

 red and yellow color, 

 micropogon, taken in Mill creek. Mr. Cope says "I only know this species from 

 specunens sent me by my friend J. Staufter of Lancaster," whether it occurs in 

 any of the other hydrographic basins is not yet known. The head is shorter, 

 convex, a dark lateral and median dorsal band, caudal peduncle slender.
