5 in a row), and with as many faint transverse bands of dusky, 

 including within them the white spots, as there are of the latter; 

 membranes of spinous dorsal each with a triangular black blotch, 

 tipping fin; along each side of base of spinous dorsal a row of smaller 

 blackish streaks; caudal, anal, ventrals, and pectorals uniform, 

 yellowish. 



Of this abundant species we have thirteen specimens — one, 13.5 

 inches long, from Nagasaki; three, 2 inches, from Tokyo; nine, 4 to 8 

 inches, from Wakanoura. It is found in rather deep clear water in 

 the southern bays. It has been identified by most recent writers 

 with Epinephelus fasciatus of the South Seas. 



As compared with a specimen of E. fasciatus 12 inches long from 

 Lord Howe Island, our Japanese specimens differ in having the 

 depth slightly less, the maxillary a A^ery little shorter, gill-rakers 

 fewer (by two rudiments), and in having the anterior triangular

dorsal blotches as deep as long (the Lord Howe specimen having all 

 the blotches longer than deep). Specimens from Queensland are 

 said by Mr. J. Douglas Ogilby to have the body deeper (2.45-2.90), 

 head longer (2.35-2.60), maxillary longer (beyond eye), and gill- 

 rakers in greater number (18) than specimens from the tropical 

 Pacific.
