fins ; and, behind each point, are five tubercles, disposed in a 

 row below the lateral line, which is straight and tuberculated. 

 The vent is before the middle. 



The foremost dorsal fin contains seven rays, of which the 

 first is hard at the lower part, and indented behind, but soft 

 and undivided at the point ; the othei's are branched. The se- 

 cond fin has only one short prickle, with a short membrane 

 behind. The pectoral fins are low, sharp above, and shorter 

 than the head. Each has twelve rays, of which the first is a 

 very strong prickle, indented on both edges ; the others are 

 branched. The ventral fins are still smaller, each containing 

 seven rays. The fin behind the vent has six rays. The fin of 

 the tail, ending in a crescent, has ten rays, of which the upper-

 body and head. The specific name has been derived from 

 this singularity.
