A single specimen 6 in. long. Head 2|, depth 3 in length ; eye 

 2J in head; D. XI, 13; A. IV, 9 ; scales 4-45-7. Dorsal outline 

 much more curved than ventral ; mouth low, but little oblique, the 

 lower jaw projecting and entering upper profile ; maxillary to below 

 middle of eye ; eye large, lower margin of orbit cut by a line con- 

 necting tip of snout and upper base of pectoral ; angle of opercle 

 high, higher than top of pupil, with three sharp teeth, small teeth 

 along the margin next the subopercle ; subopercle long and narrow, 

 dentate near upper end ; preopercle very finely serrate, with a strong 

 spine at angle ; a single row of scales on opercle along margin of 

 preopercle ; suborbital bones very narrow, finely serrate ; premaxil- 

 lary groove on top of head as long as eye ; length of pectoral equals 

 head behind middle of eye; spinous dorsal depressible into a groove, 

 highest (anterior) rays of soft dorsal equal to ventrals, longer than 

 soft rays of anal ; third anal spine very long and heavy, as long as 

 pectorals; caudal forked almost to base, the lobes equal, as long as 

 pectorals. Each row of scales with a red band, yellow lines between 

 the rows ; fins all yellowish. 



This is a strongly marked species, very different from Holocentrus 

 ascensionis, perhaps the type of a distinct genus, characterized by 

 the large mouth and projecting chin.
