 ahove the middle of the depth of the body, and has no elongate 

 scale in its axil. The spinous dorsal commences nearer to the 

 tail than to the extremity of the snont above the tenth scale of 

 the lateral line. The second dorsal commences above the twentieth 

 scale, or above the middle of the anal fm ; both fins are scaleless.
