FISHES OF THE PHILIPPHSTE AND ADJACENT SEAS 145 



reaches opposite front nostril in young, to eye with age, 3% to 3ji in 

 head; interorbital 3)4 to 33^. broadly or but slightly convex. Gill 

 rakers 6 + 14, lanceolate, 2 in gill filaments, which 2 in eye. 



Scales 42 to 45 in lateral line to caudal base, and 2 or 3 more 

 tubular on latter; 12 or 13 scales above lateral line, 22 to 27 below. 

 Scales with 7 or 8 basal radiating striae; apical denticles 56 to 62, 

 with 4 to 9 transverse series of basal elements; circuli fine. 



D. XI, 16, 1 or 17, I, fourth spine 1% to 1^4 in head, fourth ray 1% 

 to 2}/s; A. Ill, 13, 1 or 14, i, second spine l}/^ to 1%, second ray 1^ 

 to 1^; least depth of caudal peduncle 23^8 ^o 23^; caudal emarginate, 

 1 to 13^; pectoral 1}^ to 1%; ventral 13-^ to 1%. 



Ground color largely pale to white. Six broad blackish-brown 

 bands, sloping slightly downwards or posteriorly from horizontal, 

 on head and back broader than pale interspaces. Two uppermost 

 bands also extend across soft dorsal and anal, though spinous dorsal 

 with broad black band which also extends across front of soft dorsal. 

 Caudal and pectoral pale. Ventral pale, with second and third rays 

 dusky. 



China, Japan, Philippines?, Riu Kiu, Australia. 



Our specimens all agree, but differ from McCulloch's figure,^ which 

 shows the ocular band sloping to the pectoral origin above the eye 

 and not through it as in both our Port Jackson specimens. Moreover 

 these also do not show a black anal base as he indicates.
