wh ffill covers golden: lateral lino somewhat flexuose or 

 somewhat arched towards the back: tail equally forked, sinus 

 ebtuse. Dorsal fin with 1 5 rays, anal with 32, falcated, round- 

 ed anteriorly, acute behind, 



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 vernati* for this species: in {act all the 

 species ate 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 covur 

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

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

 the first anterior or opposed to the abdominal fins which have 

 a scaly appe n dage, the second adipose and opposed to the anal 

 fin. 



This Linnean genus which includes the Trouts and Salmono 

 is confined to the head waters and brooks of the '©lite. I 

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

 small streams of Ohio, the Cumberland and Clinch mountains, 

 &c. The white fish ef Lake Erie, Coregonus albua ol Lesueur, 

 (or Salmo clufleformis of Dr. Mitchell,) a fish which differs 

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

 <go7iu8,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 

 streams putting into the Missouri and Mississippi. 

 . 34th Species. Alleghany Trout. Salmo Mlegaiii&risis. 

 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 lunulate, dorsal fin quadrangular with brown stripes,
