with black dotts, breadth one sixth of the length, 

 lateral line nearly straight the anal fins very long, 

 tail truncate. I have not seen this species, I describe 

 it from a drawing made by Mr. Audubon. I am 

 therefore doubtful, whether it is a real perch, par- 

 ticularly since the drawing does not show the ser- 

 ratures and spines of the gill cover. It might be a 

 Sciena, or a Dipterodon, yet the shape of the body and 

 the distant dorsal fins, induce me to rank it with the 

 G. Perca until better known ; when it may even turn 

 out to be a peculiar genus, which the flexuose oper- 

 cule, long anal fin and vent in the middle of the 

 body, seem to indicate, and should it be a real perch, 

 it must form a peculiar subgenus, which may be 

 called Pomacampsis in either case. The vulgar names 

 of this fish are Black Perch, Widow's Perch, Dotted 

 Bass, Black Bass, Batchelor's Perch, &c. It is found 

 only in the lower parts [I. 372] \_2/f\ of the Ohio, from 

 the falls to the mouth, and it runs up the small creeks, 

 but is rare every where. Its length is from six to 

 twelve inches. The snout is rounded, the head slop- 

 ing and small, the preopercule rounded, the opercule 

 flexuose or nearly lobate; the eyes are black and 

 beyond the mouth. The back is almost black, the 

 two dorsal fins are dotted like the body, the first has 

 about twelve spiny rays, and the second about eight 

 soft rays, this last is very near the tail. The anal 

 fin has about twenty rays and begins just below the 

 vent and the end of the first dorsal fin. Vent in the 

 middle of the body, almost nearer the head.
