found occasionally as far as Pittsburgh. It is larger, 

 reaching from 3 to 5 feet and 5olbs 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^ 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.
