bands of small teeth in both jaws. None on palate. Teeth 

 on the tongue. One row of scales on praeoperculum. Oper- 

 culum with rather large scales. Dorsal separated by 13 — 14 

 scales from head. Origin of dorsal more or less behind that 

 of ventrals. Origin of second dorsal behind that of anal. First 

 ray of dorsal somewhat produced (in males only?). Anal spine 

 short, about equal to that of ventrals, shorter than eye. Pec-

torals as long as head without snout. Caudal forked. Colour 

 of preserved specimens yellowish, the scales margined with 

 brown, broader so on the back, where the pigment extends

(Kner, Novara Expedition, Fische, 1865 — 1867, p. 275). 



Small, elongate fishes. Much compressed in their hinderpart, 

 less so in the anterior half. Mouth small or large, very oblique, 

 nearly vertical, bordered by mandibles, the symphysis of which 

 is prominent, and by the intermaxillaries; maxillaries hidden 

 when the mouth is closed. Small curved teeth in both jaws, 

 some of them caniniform in males. Palate toothless. First dorsal 

 consisting of 4 — 5 undivided rays; in indo-australian species 

 far behind origin of ventrals, its origin before, above or some- 

 what behind that of anal or nearly so. Second dorsal with 

 6 — 8 branched rays, its origin behind that of anal. Anal with 

 a slender spine and 9 — 12 rays. Ventrals abdominal. Fins with 

 elongate rays in males. Caudal emarginate. Scales rather large, 

 cycloid, much larger on head, where they reach to hinderpart
