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

 head, and one-third of the total (without 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 caitre 

 of the eye. The spines of the fins are slender ; the second of the 

 dorsal is one-half of 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 blackish.

The height of the body is four times in the total length (one-third, 

 without caudal), the length of the head four and two- thirds to four 

 and three-fifths j the diameter of the eye is a little less than one -third, 

 or one-third, of the latter, and equal to the length of the snout and 

 to the width of the interorbital space. 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 contained once and three-quarters 

 in the height of the body ; the second of the anal shorter than the 

 third. Silvery : each spine and ray of the dorsal with a brown basal 

 spot ; the spinous portion black-edged.
