space between prEeoperculum and suborbitals very narrow. Gill-rakers 

 very short, rudimentary. Dorsal III 8, originating midway between 

 occiput and root of caudal, or a little nearer latter, its posterior third

 reaching ventral. Caudal forked. Caudal peduncle twice as long as 

 deep. Scales with radiating stria?, 44-45 gj, 1 between lateral line and
