1. GEREE8. 255 



intermaxillary bones is broad, triangular, entirely scaleless, and does 

 not reach to the vertical from the centre of the eye. The dorsal 

 spines are rather slender and slightly compressed ; the second is once 

 and three- fifth 8 in the length of the head. The second anal spine is 

 rather strong, stronger and a little longer than the third ; its length 

 is once and two-fifths in that of the head. Caudal fin deeply forked, 

 entirely covered with scales ; the length of a lobe is nearly three and 

 a half in the total. Uniform silvery ; the margin of the dorsal fin 

 blackish,

The height of the body is twice and three-fourths in the total length 

 (without caudal fin). Praeorbital and praeoperculum entire, the latter 

 with the angle slightly rounded. The groove for the processes of the 

 intermaxiUaries extends nearly to the vertical from the centre of the 

 eye ; a transverse stripe of scales covers a part of the groove, sepa- 

 rating from it the posterior third *. The snout is shorter than the 

 diameter of the eye, and equal to the space between the eyes. The 

 spines of the fins of moderate strength ; the second and third of the 

 dorsal half as long as the head, but twice as long as the second of the 

 anal. Silvery : dorsal fin minutely dotted with brown ; the dots more 

 crowded at the top of the dorsal.

The height of the body is one-third of the total length (without 

 caudal fin). Praeorbital and praeoperculum entire, the latter with 

 the angle slightly rounded. The groove for the processes of the in- 

 termaxillaries extends to the vertical from the centre of the eye, is 

 elongate, and entirely free of scales. The snout is sKghtly longer 

 than the diameter of the eye, which exceeds the width of the head 

 between the eyes. The spines of the fins moderate ; the second of 

 the dorsal is longer than one-half of the length of the head, and 

 nearly twice as long as the second of the anal. Silvery : a deep- 



* Space between the eyes with a fovea in the middle (Jenyns, I. c).
