DUSKY SEREANUS. 17 



plate. The gill-covers are not ridged. In its aspect this 

 fish has some resemblance to the Labri, yet it has none of 

 the generic characters by which these fishes are distinguished. 

 That it should be placed among the Perches, I make no ques- 

 tion ; but my most industrious search has not been able to 

 find that it has been either figured or described : until, there- 

 fore, some other naturalist shall be more fortunate, I venture 

 to denominate it Perca robusta, from its great size and 

 strength. I have never seen more than one specimen, which 

 was taken with a line." In accordance with the remark 

 made by Mr. Couch, Cuvier mentions that the Spanish 

 name for this fish signifies a Labrus. 



The term Dusky Serranus is suggested for it, instead of 

 Dusky Perch, the better to identify it with the sub-genus to 

 which it belongs.
