It will appear that this fish differs so widely from the forego" 



ing, as to be hardly reducible to the same genus; but its great 



similarity with the Perca Mitchelli has compelled me to retain 



it in this genus, notwitstanding many peculiar characters. I 



shall however venture to propose a new subgenus or section in 



the genus Perca for this fish, to which the P. Mitch clli> may 



perhaps be found to belong. It may be called J.ejiibema and 



distinguished by the scaly bases of the caudal, anal, and second 



dorsal fins, this last with some spiny rays, and all the three parts 



of the gill cover more or less serrulate, besides the small teeth. 



The Perca Salmonca may also form a peculiar subgenus, or 



section distinguished by the cylindrical shape of the body, long 



head and jaws, large teeth, and a second spine outside of the 



opcrcule over the base of the pectoral fins. It may be called 



Stizostcdiori, which means pungent throat. I could have made 



peculiar genera of each of them, under the proposed names; but 



as they otherwise agree with the reduced genus Perca, I have 



preferred delaying this innovation until more species are found 



possessing the same distinctions, in which case my two perches 



may then he called Siizuvtcdion salmoTuinr., and Pejiibcma chrij-

Upper jaw longer; body brown, covered all over 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 spe- 

 cies, I describe it from a drawing made by Mr. Audubon. I am. 

 therefore doubtful, whether it is a real perch, particularly since 

 the drawing does not Bhow the serratures and spines ol the gill 

 cover. It might be a Scima, or a Di/Ucrodon, 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 filexuosc opcrcule, 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 

 he called Poma cam/mis in either case. The vulgar names of 

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

 Bass, Batchclor's Perch, Sec. It is found only in the lower parts
