equal to the length of the head, and nearly in a line dividing 

 the distance between the origin of the ventral and anal fins ; 

 the second dorsal fin begins on a line a little behind the 

 origin of the anal fin, and being shorter than that fin, ends on 

 the same line with it. The general lengths of the longest of 

 all the various fin-rays are nearly equal to each other, and 

 about equal to three-fourths the length of the head ; except 

 the caudal fin, the rays of which are longer, and the tail con- 

 siderably forked. 



The colour of the top of the head and back is dusky grey 

 tinged with blue ; the sides and belly silvery white, marked 

 with longitudinal parallel dusky lines ; membranes of the fins 

 dull white : cheeks and operculum silvery white ; iricles red- 

 dish brown, pupil black, surrounded by a silvery line. The 

 pectoral fin has a dark spot at the base of the three or four 

 upper rays. 



The vignette below represents the head of this species as 

 seen from the side and from below ; in the latter view it 

 will be observed that the inferior edges of the interopercula 

 do not hide the space under the tongue.
