the depressions: extremity of the saw rounded nearly truncate, 

 with a raised granular margin reflected upwards. 



I have only seen the saw of this fish, which is preserved in 

 Mr. Clifford's museum. It is six and a half inches long, and 

 one broad, olivaceous above, pale beneath, middle part raised 

 but flat. Teeth half an inch long, shorter and more distant near 

 the base, 26 on the right and 27 on the left, nearly equal. This 

 fish is found in the Mississippi, Lake Pontchartrain, Red River, 

 Arkansas, Mobile, and has even been seen in the Ohio, length 

 from three to six feet. 



XXXVIIl Genus. Hornfish; Proceros. Proceros. 

 Apoddi. Body elongated. Vent posterior. One dorsal fin 

 opposed to the anal. Mouth beneath transversal toothed. Snout 

 protruded in a a straight horn. Four spiracles or branchias on 

 each side. 



Singular new genus of the family of Sharks or Antacea^ from 

 which however it difl'ers by Ihe want of abdominal fins. There 

 are two species of it: the second, which I have called Proceros 

 vietatusj lives in Lake Ontario, and has longitudinal stripesl'* 



11 1th Species. Spotted Hornfish. Proceros maculutussi 

 Proceros tacheteii 



Iron grey 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 set- 

 tlers call it P@isso7i arme. It has no scales, but its head is bony: 

 Eyes very small. Dorsal and anal fine rounded. Length two 

 or t^hree feet, vei'y good to eat. Communicated by Mr. M— — 

 of St. Genevieve. 



Several imperfect and incorrect notices or Catalogues of fish- 

 es 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 riv- 

 ers, 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 perhaps from the two 

 latter travellers. I may at a future period notice the new fish- 

 es of the Missouri, discovered 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 chrysofis^ is found in the Wabash, and called 

 Rock-mullet, it reaches three feet in length and fifteen prounds 

 in weight. This fish will not bite at the hook, unless when it 

 is withdrawn, it then darts on it. 



4th Sp. Amblodon ^runniens. It is sometimes called Drurm 

 in the Wabash.
