found occasionally as far as Pittsburgh. It is larger, 

 reaching from 3 to 5 feet and 50IDS weight. Not 

 very good to eat. It has been so fully described by 

 Lesueur, that I need not do it again. The individ- 

 ual which I saw was 40 inches long, head 20 inches, 

 snout 1 1 inches long and 2 y 2 wide at the end, hardly 

 cun[e]iform. Eyes exceedingly small and round. 

 Gill cover oval radiated as in the Sturgeons, with a 

 short, membranaceous flap, reaching only beyond the 

 pectoral fins, &c. It is also called, along with the 

 foregoing, Oar fish and Spatula fish. 



XXXV Genus. Lamprey. Petromyzon. Lamproie. 



Body cylindrical scaleless, vent posterior. Two 

 dorsal fins and a caudal fin, no other fins. Seven 

 branchial round holes on each side of the neck- 

 Mouth terminal inferior acutiform, toothed. 



There are two or three species of Lampreys in the 

 Ohio ; but they are very scarce and I have only seen 

 one as yet. 



104th Species. Black Lamprey. Petromyzon ni- 

 grum. Lamproie noire. 



Entirely blackish, tail oval acute, second dorsal 

 over the vent, several rows of teeth. 



[III. 252] A very small species, from four to five 

 inches long; it is found as high as Pittsburgh. Dor- 

 sal fins shallow, and distant from each other and the 

 tail. Eyes round and large. Branchial holes small. 

 No lateral line. Mouth oval, teeth white and yel- 

 low. It torments sometimes the Buffaloe fish and 

 Sturgeons, upon which it fastens itself. It is never 

 found in sufficient quantity to be used as food.
