 peduncle and forward of a line intersecting the origin of first 

 dorsal, which are smaller, those on nape and belly much smaller ; 

 the tips of all the first dorsal spines more or less elongate, the 

 second, third, and fourth longest and extending beyond origin or 

 to fourth or fifth ray of second dorsal when depressed, longer 

 than head, 3.95 to 4.3 times in length; the second dorsal 1.33 to 

 1.5 times in head, ^ to as high as first dorsal, angulate poste- 

 riorly, not reaching caudal when 

 depressed, the middle rays long- 

 est; the anal like second dorsal 

 but only f or 0.75 as high; the 

 depth of caudal peduncle equals

 1.65 to 1.8 times in head; the 

 caudal truncate to bluntly round-
