 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 considerably forked.

 with longitudinal parallel dusky lines ; membranes of the 

 fins dull white ; cheeks and operculum silvery white ; irides
