Plate X. Fig. 2. 



Head elongate, sloping from the base of the skull to the 

 tip of the nose, longitudinally sulcate between the eyes. 



Lower jaw longer, the front teeth short, the lateral elevated 

 and larger ; a series of large glandular orifices evident on the 

 edge of the lower jaw and preoperculum. 



Body sub-cylindric, compressed laterally ; back rounded, 

 slightly depressed longitudinally before the dorsal fin ; scales 

 emarginate, small. 



Dorsal and a7ial fins rounded, the former larger, the 

 latter slightly posterior, both placed on fleshy bases. 



Caudal fin bi-lobed, lobes obtuse, rounded. 



Ventral and pectoral fins small, short and falcate. 



Color. Head and hack deep olive and green, sides yellow- 

 ish, marked with oblique and longitudinal bars of green, 

 which give them a reticulated appearance : throat and belly 

 white. Dorsal^ caudal and anal fins yellowish and reddish, 

 reticulated in a similar manner with bands and spots of 

 deep olive or green. 



Length. The specimen before me is 21 inches. Some 

 are taken that are 4 feet in length. 



Habitat. Lake Erie, the Ohio river and most of their 

 tributaries. 



D. 18 ; C. 20; A. 15; Y. 11 ; P. 16 rays. 



Observations. The drawing was made from a specimen 

 taken at Cleveland. The colors were darker and more bril- 

 liant than in any that I have seen. The number of rays in 

 the caudal and anal fins does not agree with Le Sueur's de- 

 scription. 



It is probably specifically identical with the fish known in
