Ish, gill corers golden: lateral line somexvhat flexuose or 

 somewhat arched towards the bac4i: tail equally forked, sinus 

 obtuse. Dorsal fin with 15 rays, anal with 32, falcated, round- 

 ed anteriorly, acute behiud, 



This fish was observed by Mr. Lesueur in Lake Erie. Mr. 

 Say thinks he has seen it at Pittsburgh; but I have never ob- 

 served it in the Ohio, and I suspect that Mr. Say may have 

 mistaken the Hyodon vernalis for this species: in fact all the 

 species are blended by the fishermen and considered as alike; 

 I therefore introduce it among the fishes of the Ohio with some 

 doubt. It has the same eyes and colours as the foregoing. 

 Length thirteen inches. Good food. See Mr. Lesueur's mi- 

 nute description. 



XIV Genus. Trout. Salmo. Truite. 



Body somewhat cylindrical scaly, vent posterior. Gill cover 

 double, scaleless, more than four rays at the branchial mem- 

 brane. Mouth large, jaws with strong teeth. Two dorsal fins, 

 the first anterior or opposed to the abdominal fins which have 

 a scaly appendage, the second adipose and opposed to the anal 



fin. 



This Linnean genus which includes the Trouts and Salmon© 

 is confined to the head waters and brooks of the Ohio. I 

 only know two species as yet; but there may be more in the 

 small streams of Ohio, the Cumberland and Clinch mountains, 

 Sec. The white fish ©f Lake Erie, Coregonus albus o\ Lesueur, 

 (or Salmo clufieformis oi Dr. Mitchell,) a fish which differs 

 from the Trouts by being toothless, and is therefore a real Cor- 

 egouus^ is said to be found in some streams of Indiana, at the 

 head of the Wabash and Miami; but I have no certain proof of 

 it. Other Trouts have been seen in the Osage river and other 

 jstreams putting into the Missouri and Mississippi. 

 , 34th Species. Alleghany Trout. Salmo Alleganiensis. 

 Truite alleganienne. 



Back brownish, sides pale with crowded round fulvous spots, 

 and some scattered scarlet dots above and beneath the lateral 

 line, which is nearly straight: lower jaw^ hardly longer, tail red- 

 dish nearly lunuIatCj dorsal fin quadranjjulur with brown stripes,
