fill rays, — of the dorsal thirty-one, of which twelve are in the 

 first division of the fin; anal fin nineteen; caudal eleven; 

 pectoral thirteen; ventral two. There are eighteen teeth in 

 the lower jaw, between the two hooked canine teeth. 



In one instance there has been met with a curious deviation 

 from the usual structure of this fish, and that too in an 

 important particular. It was fully grown, but on the left 

 side was altogether destitute of a pectoral fin, and in the place 

 of it a depression which shewed that the loss was not the 

 consequence of injury. But as a compensation for this there 

 were three rays instead of two in the ventral fin of that side. 

 This additional ray was less in size than the others.
