 Ptychostomus duquesnei (Le S.) Ag. 



Descriptiou uot very good. The common " Red-IIorse" of the Ohio 

 is certainly Le Sueur's duquesnei. Professor Cope recognizes lialiues- 

 que's species as distinct, but I have not yet been able to separate it. 



t64th species, Kentucky Sucker, CATOSTOMUS FLEXUOSUS, Catos- 

 tome flexueuz. (p. 59.) 



CATOSTOMUS TERES (Mitch.) Le S. 



Description fair. Professor Agassiz is certainly wrong in referring this 



species to the Cat. nigricans of Le Sueur. The description accords 



better with Cat. teres, and the statements with regard to the habits 



and common name point very strongly to this species, which is still 



known everywhere in Kentucky as the "Sucker".

 A myth. 



* Diameter one-liftli of the length : rufous hrowu above, white beneath: tail oliva- 

 ceous : head convex, snout rounded : lateral line straight : dorsal fin trapezoidal, I'ed- 

 dish with 12 rays: anal fin elongated, yellow, anal falcated, with 7 rays. 



A fine species, not uncommon iu the Ohio, Kentucky, Cumberland, Tennessee, «fec. 

 Vulgar names: Red-horse, Red-tail, Horse-fish, Horse- Suckers, &c. Length about 

 one foot. Scales very large. Mouth beneath. Iris whitish, eyes black. Pectoral fina 

 yellow, elliptical, reaching the abdominals, aud with 16 rays. Tail large with 20 rays. 

 Its flesh is dry and not very good to eat. 



t Diameter oue-fifth of the length ; silvery, back brownish, scales rather rough, oper- 

 cnle flexuose; head squared, snout gibbose truncate; lips very thick, the inferior 

 bilobed ; lateral line flexuose ; tail brown ; dorsal fin blackish with 12 rays, anal fin 

 w'hitish with 7 rays'aud reaching the tail. 



The most common fipecies, in Kcnludy, in all ihe streams and ponds, called merely Sticker. 

 Very good to eat. It conceals itself in the mud in winter. It bites at the hook, liv- 

 ing on minnies aud little lobsters. Body thick cylindrical. From 10 to 12 inches 

 loug. Head large, a deep depression between the snout and the head, mouth large 

 with fleshy lips. Eyes large, black, iris yellow. Opercule bard bony. Lower fins 

 M hitish, pectorals elongated elliptical with 20 rays. Tail 20 rays. Dorsal trapezoidal, 

 sloping behind. This fish is the most useful to keep in ponds. 



t Diameter one-fifth of the length; blackish above, yellowish beneath, very broad; 

 a spine at the base of the pectoral fins ; lateral line straight. 



A very doubtful species seen by Mr. Audubon. It conies sometimes in shoals iu March, 

 and soon disappears. Only taken with the seine, not biting at the hook ; vulgar name, 

 Brown Sucker. The mouth is very remarkable, being broader t ban the head, somewhat 

 projecting on the sides; length one foot. The head resembles that of a Cat-fish, but 

 has no barbs. Is it a peculiar genus owing to the mouth and pectoral spine? It might 

 be called Eunjsiomus. The yellow color covers the forehead and reaches to the anal fin. 

 Dorsal opposed to the abdominal and trapezoidal, pectorals elliptical, yellow.
