The posterior extremity of tlie maxilla extends nearly as far as to 

 beneath the anterior margin of the orbit. The posterior limb of the 

 intermaxillanes extends to opposite the anterior margin of the orbit. 

 Praeorbital two-thirds as wide as the orbit. Prtcapcrculum a little 

 emarginatc, its angle slightly produced, serrated in its whole extent, 

 but coarsest at the angle, the lower limb two-thirds as long as the 

 vertical one, and with some i'ew serrations along its posterior part. 



Teeth villifbrm, in several rows anteriorly, becoming a single one 

 posteriorly, some also on vomer and palate. ° 



Fins. Dorsal spines strong, every alternate one broadest, inter- 

 spinous membrane slightly emarginatc ; fourth spine the longest • 

 last spme three-fourths as high as the first ray. Pectoral pointed' 

 Ventral spme not very strong, its first ray with a short filamentous 

 prolongation. First anal spine weak, and one-third as long as the 

 second, which is strong and one-fourth longer than the third, which 

 IS striated anteriorly and laterally, and has a smooth keel anteriorly 

 half the width of the spine. Caudal slightly lunated. 



Scales in horizontal rows, except to the first seven dorsal spines 

 to which they ascend irregularly upwards and backwards. There 

 are some fine scales between the dorsal and anal rays. 



Lateral line follows the course of the back. 



Colours. Greyish, becoming white along the abdomen. A brilliant 

 yellow band passes along the centre of a row of scales from opposite 

 to the centre of the orbit to the centre of the base of the caudal fin. 

 A similar one passes a short distance along the centre of the row above 

 It. Dorsal and caudal fins greyish, soft dorsal with a lio-ht margin. 

 Pectorals, ventrals, and anal yellowish. Eye golden. ° '^ 



I have named this species after mv esteemed correspondent A. C B

Eyes circular, upper margin close to the profile, diameter 4 of 

 length of head ; | of a diameter apart, ^ a diameter from end of snout. 



Body rather elongated and compressed ; head slightly depressed. 



Mouth anterior, lower jaw the longest; posterior extremity of the 

 maxilla rather wide, extending to beneath the anterior third of the 

 orbit ; the posterior limb of the intermaxillaries likewise extends back- 

 wards in the central line to opposite to the same place. Prsorbital 

 long, narrow, and at least three times as long as wide, and with ele- 

 vated striae upon it. Praeoperculum wide, its horizontal wider than 

 its vertical limb ; both striated at their edges, and irregularly serrated.
