MITCHILL ON THE FISHES OF NEW-YORK. 459 



2. Chub of New-York. (Cyprinus oblongus.) Mouth under, small, 

 puckered, and toothless. Head somewhat depressed and smooth. 

 Eyes rather small. Gill-openings rather narrow. Pectoral fins very far 

 forward on the neck. Back arched and approaching to gibbous. Body 

 thick, but may be rather termed deep than round. 



Back deep brown, inclining to black, with whitish scales. The lines 

 between the scales, dark and decussating each other so as to leave rhom- 

 bic spaces between them. The lines are darker coloured than the 

 spaces they define. 



Belly a pale cream colour, with golden spots or tints, particularly be- 

 tween the pectoral and ventral fins, and near the anal. 



Pectoral and ventral fins dusky, with a reddish tinge. Anal, caudal, 

 and dorsal, dark brown. 



Lateral line obscure. Tail rather concave.

Lives in fresh streams and lakes like the sucker. 



3. New-York Shiner. (Cyprinus crysoleucas.) With lateral line 

 crooked downward. 



Mouth small, even, and toothless. Head smooth and rather diminu- 

 tive ; and lengthened, or depressed on the upper side. Flesh soft. 

 Scales deciduous. A single dorsal fin, and that situated far back. 



Eyes large in proportion to the head, and bright ; body deep in pro- 

 portion to its length. 



Colour blackish, with shining white scales. Gill-covers golden, with 

 a tinge of the same along the belly. Head often greenish ; and when 

 the scales fall off, the back is frequently tinged with green and blue. 



Lateral line bends downward to correspond with the curve of the ab- 

 domen. This appears only when the scales are on ; there is another 

 and a straight one which appears only when the scales are off.
