14 AKT. 13. — S. TANAKA : 



the upper and lower profiles gently declined anteriorly ; eye 

 moderate, lateral, very close to upper profile of head ; interorbital 

 broad, gently convex ; snout moderate, the profile moderately 

 oblique ; nostrils in two pairs, in front of eye. Mouth large, 

 oblique ; lower jaw slightly included. Teeth on both jaws slender, 

 close-set, arranged in a rather broad band ; tip of upper jaw 

 notched, non-toothed, fitted to symphysis of lower jaw. Teeth on 

 palatines smaller, conical, in one row ; none on vomer. Maxillary 

 extending to the vertical through the middle between centre of 

 eye and tip of opercular flap. No barbel near mouth-parts. 

 Suborbital parts smooth, without spines ; a very small spine at 

 angle of preoperculum. 



Gill-openings wide, procurrent below and slightly confluent. 

 Pseudobranchise developed. Gills 4 ; no pit behind last gill ; 

 gill-rakers on first gill-arch small, slender, set apart from one 

 another, about 4 + 18. Pectoral situated rather low, its base 

 rather narrow ; the rays long, a little shorter than head, ex- 

 tending to the sixth ray of anal. Ventral thoracic, beneath 

 lower margin of base of pectoral, extending to the middle between 

 insertion of ventral and that of anal. Vent midway between 

 tip of ventral and insertion of anal. 



Dorsals 2, separated from each other by a very short 

 interval ; first dorsal inserted slightly behind insertion of pectoral, 

 the membrane joining the spines adnate to body posteriorly, but 

 not continued to second dorsal ; second dorsal long, higher than 

 first dorsal ; whether a membrane exists or not behind the last 

 ray of dorsal is uncertain owing to the mutilation of all the 

 specimens. Anal below third ray of second dorsal ; both fins 

 higher anteriorly, similar in form. Caudal forked. 



Skin smooth, without scales ; lateral line rather high.
