156 ICHTHYOLOGIA OHIENSIS 



abdominal fins. There are two species of it: the 

 second, which I have called Proceros vittatus, lives in 

 Lake Ontario, and has longitudinal stripes. 



1 1 ith Species. Spotted Hornfish. Proceros ma- 

 culaUis. Proceros tachete. 



Iron gray with white spots on the sides: tail 

 forked: horn one fourth of total length. 



This fish lives in the Mississippi, and is sometimes 

 caught at St. Genevieve in the State of Missouri. 

 The French settlers call it Poisson arme. It has no 

 scales, but its head is bony: Eyes very small. Dor- 

 sal and anal fins rounded. Length two or three 



feet, very good to eat. Communicated by Mr. M 



of St. Genevieve. 



Several imperfect and incorrect notices or Cata- 

 logues of fishes living in the western waters have 

 been published. Carver and Pike have noticed those 

 of the Upper Mississippi, Curtis those of Red River, 

 Pike those of the Arkansas and Osage rivers, Thomas 

 those of the Wabash, and Lewis and Clarke those of 

 the Missouri; but very few practical facts can be 

 collected from their imperfect accounts, except per- 

 haps from the two latter travellers. I may at a future 

 period notice the new fishes of the Missouri, discov- 

 ered by Lewis and Clarke. I shall at present merely 

 add some facts lately ascertained or drawn from 

 Thomas's account of the fishes of the River Wabash, 

 page 211 of his travels published in 1819. 



2d Sp. Perca chrysops, is found in the Wabash, and 

 called Rock-mullet, it reaches three feet in length 

 and fifteen pounds in weight. This fish will not 

 bite at the hook, unless when it is withdrawn, it then 

 darts on it.
