pupils) 3; snout 4; D. XII, 15; A. Ill, 11; scales in longitudinal 

 series above lateral line to last vertebra 45; in series below 40; on 

 lateral line 42; in transverse series 10/16; gill rakers 6 + 13; length of 

 longest one-half diameter of eye. 



Body deep; dorsal and ventral profiles similar and symmetrical; 

 compressed; caudal peduncle deep, 2 J- in head, its length from last 

 anal rays to base of caudal 3 in head; head slightly concave in profile 

 back of interorbital area, strongly convex from side to side; snout 

 very much rounded, broad, its length less than its width; suborbitals 

 very narrow, less than half width of the small eye; lower jaw longer; 

 maxillary extending to below posterior border of eye; mouth cleft 

 very oblique, at about 40° to body axis, its tip at lower level of eye, 

 laterally fully the diameter of the eye below. Teeth in outer rows 

 of both jaws conical, not at all compressed nor canine-like, rather 

 closely -set. Inner band of upper jaw broader anteriorly than that 

 of lower, both becoming narrower posteriorly, those above being of 

 five or six rows in front, those below three or four; outer row teeth 

 stoutly conical, somewhat enlarged. 



Preopercle set with bony teeth, projecting little beyond bony mar- 

 gin, making rather coarse serrations, stronger at the slightly projecting 

 angle, small and pointing upward on dorsal half of posterior border; 

 downward on lower border, but lacldng on anterior half of latter, the 

 remainder small. Portion of posterior border of interopercle and 

 whole free edge of subopercle finely serrated, as is the clavicle and the 

 posttemporal. These serrations are much larger in young examples. 



Dorsal spines longest in fourth and fifth, about 2f times in head, 

 stout and strong. Spinous dorsal base 2| in body to base of caudal, 

 soft dorsal 3§. Anal spines graduated, third and longest, about 4 

 times in head; soft anal rounded; anal base four in length to base of 

 caudal. 



Lateral line following line of back, arched strongly anteriorly, the 

 tubes simple, large. 



Scales thick and bony, rather large and coarse, slightly ctenoid; cov- 

 ering basal halves of soft dorsal and anal and basal third of caudal; 

 those on head and cheeks much smaller; those on opercle in seven 

 rows, of eight or nine scales along border, on subopercle in one 

 lengthwise row of six or seven, on interopercle in one of ten or eleven, 

 with two partial rows. Scales lacking on snout before nostrils, on 

 lips and lower jaw. 



Color dark olive, especially dark on head. Lining of gill cavity and 

 peritoneum clear; distal part of caudal fin paler. In life, blackish 

 above, silver gray below, often blotched or tinged with yellow. 



Of this species of wide distribution in the warm seas, one specimen 

 only is known from Japan. This was found dead on the beach at
