the fish. Eye large ; diameter equal to between one quarter and one 

 third the length of the head from tip of upper jaw to opercular 

 edge; equal to, or a little more than the interorbital space; less than 

 the post-orbital portion. Caudal fin forked; lower lobe longest. 

 Pectorals very long, about one fourth the length of the fish, under 

 jaw excluded. Yentrals very small, about one sixth the length of 

 the pectorals, and placed nearer to the base of the caudal than to the 

 head. Dorsal and anal long, with high anterior rays; placed opposite 

 each other, but the dorsal commences a few rays in advance of the 

 anal. 1 Abdomen and sides silvery; above darker. Scales large, wide 

 and short. Pectoral, I, 7 = 8; ventral, I, 5 = 6; dorsal, i, ii, 19 or 

 20 = 22 or 23; anal, I, ii, 18, or ii, ii, 17, or n, ii, 19= 21 to 23; 

 caudal, in, i, 7-f-7, i, in = 22.

 the one described by Gill, the dorsal commences a few rays in advance of the anal, 

 as represented in Valenciennes' figure of H. macrorhynchus.
