1. GERRES. 259 



The second anal spine is much stronger but scarcely shorter than the 

 third, and not quite half as long as the head ; the scaly sheath covers 

 the posterior anal rays entirely. Pectoral very long, extending to the 

 second anal spine. Silvery ; each dorsal ray and the posterior spines 

 with a blackish dot near the base.

The height of the body is "two -fifths of the total length (without 

 caudal); the diameter of the eye is one-third of the length of the 

 head, equal to the width of the interorbital space, and more than the 

 extent of the snout. The groove for the processes of the inter- 

 maxillaries does not extend beyond the vertical from the front margin 

 of the eye and is not scaly. The free portion of the tail is scarcely 

 longer than high. There are only thi^ee longitudinal series of scales 

 between the uppermost part of the lateral line and the scaly sheath of 

 the spinous dorsal. Dorsal spines slender, half as high as the body 

 and two-thirds as long as the head. The second anal spine is strong, 

 shorter than the third, its length being contained thrice and a third 

 in the height of the body and twice and two-fifths in the length ot 

 the head. The length of the caudal lobes is two-ninths of the total. 

 Silvery; the spinous dorsal with a black margin ; each dorsal ray with 

 a blackish dot in the middle.

The height of the body is two-fifths of the total length (without 

 caudal fin). Prseorbital and prseoperculum entire. The snout is rather 

 longer than the eye, the diameter of which equals the width of the 

 interorbital space and is two-sevenths of the length of the head. The 

 groove for the processes of the intermaxiUaries is entirely scaleless, 

 and extends beyond the front margin of the eye. The second dorsal 

 spine is considerablj- longer than the third, its length in adult spe- 

 cimens being more than one-half of the height of the body ; in half- 

 grown specimens it is scarcely longer than the third, and half as high 

 as the body. The scaly sheath of the dorsal fin is moderately de- 

 veloped. The second anal spine is stronger and a little longer than 

 the third, its length being more than one-half of the length of the
