is slightly decarved when present on the anterior half of the body. 
The candal tin is long and very deeply furcate. It is contained 
times in head and body, and the median rays are about two-lifths the 
length of the longest. The dorsal is high, its longest ray reaching nearly 
or quite half the distiince from front of dorsal to tail. The front of the lin 
is a little nearer nose than caudal. The pectorals extend about three- 
fourths the distance to the ventrals, and the latter nearly or quite attain 
the vent. D. I, 7 or 8 ; A. I, 7 or 8; scales 5, 38-40, 4, with 15 or IG rows 
before dorsal. The pharyngeal bones are thin, and suddenly and 
broadly dilated at outer third, this part of the bone being nearly 3 times 
as wide ns the inner, and in shape not uidike a horse’s jaw-bone. The 
oilontoid i)rocess is unnsnally distinct and high. The teeth are very 
slender, strongly hooked, and sharply and irregularly cremate, the edges 
ha ving a spinose appearance. The scales are crowded, higher than long, 
and wanting on the anterior half or two-thirds of the breast. Color in 
alcohol yellowi.sh brown, with a faint silvery lustre on sides. A narrow, 
black band, about one scale wide, extends around the nose, through the 
upi)er half of the eye, to the tail, terminating therein the most highly col- 
ored specimens in a narrow vertical bar. The scales above the lateral 
band are all dark-edged. In all the specimens the dorsal shows a large 
submedian blotch in Iront, crossing about 4 rays. In one this blotch is 
so enlarged as to include the whole anterior half of the tin, except a 
small space at base, and a second blotch extends similarly across the 3 
posterior rays, leaving only a narrow i)ale vertical stripe between. 
Length of largest s])ecimen inches. Several siiecimens from the 
Illinois Liver at Pekin and Peoria, and from Mackinaw Creek.” {Forbes.)
