The height of the body is 3^ in the total length, the length of the 

 head 3f ; the diameter of the eye is 1^ in the length of the snout, 

 and 3|- in that of the head. The cleft of the mouth is rather wide, 

 the upper maxiUary reaching a little beyond the front margin of the 

 eye. The praeoperculum is finely and equally denticulated, with the 

 posterior limb slightly emarginatc. The dorsal fin deeply notched, 

 with the spines of moderate strength ; the fourth is the longest, 2| 

 in the length of the head. Caudalis forked, and enveloped by scales 

 nearly to its extremities ; the second anal spine much stronger, but 

 scarcely longer than the third, 2A in the length of the head ; ventral 

 and pectoral fins covered with scales. Each scale with a darker 

 centre, the spots forming more or less distinct oblique streaks. A

The fish described by Agassiz {I. c.) agrees much better with H. 

 chromis than with H. canna, Cuv, The number of the soft rays of 

 the dorsal fin, the extent of the upper maxillaiy, and the less distinct 

 oblique streaks, are the characters by which H. chromis may be 

 distinguished from H. canna.
