A NEW ACANTHOCYBIUM. 285 



tions and literature- relating to this species (now called Cybiiim 

 solanderi Cuv. and Val.), I am convinced that this species is 

 distinct. 



The most striking features of A. forbesi are the peculiar, long 

 thin scales on the belly and the branches of the lateral line, 

 points of which I am sure the numerous careful naturalists 

 who have examined C. solanderi (C. sara) would not have failed 

 to mention in their descriptions. Also Jordan and Evermann 

 described A. solanderi as having serrated teeth. The teeth of our 

 specimen are apparently smooth. The above and several other 

 points of differences, especially in the location of the fins, seem 

 to make it necessary to describe our specimen as a distinct 

 species.
