 a little longer than the diameter of the eye, which is one-third of 

 the length of the head. Si)ines of fins of moderate length and 

 strength ; the second of the dorsal one-half the height of the body

The height of the body is scarcely more than the length of the 

 head, and is one-third of the length of the body (without the 

 caudal fin) ; the diameter of the eye is one-third of the length of 

 the head, and rather longer than the snout, the extent of which 

 equals the distance between the eyes. The groove for the processes 

 of the intermaxillary bones is entirely scaleless, and does not 

 extend to the vertical from the centre of the eye. The spines of 

 the fins are slender ; the second of the dorsal is one-half the 

 height of the body and more than twice the length of the second 

 anal spine, which is rather stronger, but not longer than the third. 

 Silvery ; top of the dorsal fin blackish.
