Head moderate, subconic; no elevation of profile above upper eye; 

 upper eye slightly posterior, its diameter 0.075; interorbital space 

 narrow, naked only in its central portion, its ridge extended from the 

 anterior margin of the lower orbit to the posterior margin of the 

 upper orbit; nostrils in the same horizontal line, the anterior pro- 

 vided with a short acuminate flap; snout sharp, its length from 

 upper orbit 0.09, its outline not parallel to anterior margin of lower 

 orbit; mandible shorter than the upper jaw, anterior teeth of premax- 

 illaries wholly without the mandibular symphysis; mandible and 

 premaxillaries strongly curved, so that for their anterior third the 

 cleft of the mouth is horizontal, for their posterior end the mouth 

 is oblique; maxillary of eyed side 0.13, extending to below pupil of 

 lower eye; ridges of head not sharply developed; no spines nor 

 tubercles; teeth uniserial, developed equally on both sides of jaws, 

 about 8 moderate canines on each side of mandible, which has no

 vided with 4 canines, the lateral teeth of upper jaw small and sharply 

 conic, about 40 in number; vomer and palatines toothless; gill-rakers 

 short, none on upper limb, 8 on lower limb, each curved strongly 

 behind and provided with 3 spinules; length of longest gill-raker 

 about 0.24 of the diameter of upper eye. 



Body elliptical, compressed, the width about 7 in depth; depth of 

 caudal peduncle 0.09. Anus on blind side. 



Scales moderate, caducous, cycloid on both sides. Snout and 

 jaws naked; pectorals and ventrals naked. Arch in lateral line 

 rather low, its length 0.13, its height 0.05; no lateral line on blind 

 side. 



Dorsal fin originating slightly on the blind side, at the posterior 

 end of the premaxillary spine, on a level with the lower margin of 

 the upper orbit, its longest rays about 0.16; anal similar to dorsal; 

 caudal subsessile, rather pointed, length 0.18; anal spine absent, 

 pubic spine present; pectoral of eyed side slightly pointed, with 13 

 rays, its length 0.15; pectoral of blind side shorter and more rounded, 

 with only 10 rays, its length 0.09; each ventral of 6 rays; base of 

 right ventral contained not quite two times in the base of left ventral.
