FISHES OF THE PHILIPPINE AND ADJACENT SEAS 133 



ScpJes 25 to 28 between gill opening and caudal base; tubes 24 to 

 27 in lateral line; 6 scales above lateral line, 14 or 15 below. Scales 

 with 9 to 15 basal radiating striae, with age many as 6 incomplete 

 auxiliaries; apical denticles 108 to 248, with 17 to 19 transverse 

 series of basal elements; circuli fine. 



D. XII, 2.3, I or 24, i, last spine IJ^ to 2 in total head length,, 

 twelfth ray 1^ to 1^; A. Ill, 19, i or 20, i, third spine IJi to 2%, 

 eleventh ray 1% to 1%; least depth of caudal peduncle 3 to S}4: 

 caudal 1% to 13^^, hind edge nearly truncate or slightly convex; 

 pectoral l}4 to 13^; ventral 1)4 to 1%. 



Dull brownish generally, paler below. Broad blackish-brown ocu- 

 lar band from interorbital, wide as eye in young and becoming broader 

 with age, scarcely narrowing on cheek. Lunar blackish-brown blotch 

 on predorsal above occiput. Blackish-brown crescent along soft dor- 

 sal base and front of caudal peduncle, but not continued down on 

 anal base, in young this blotch larger at front of soft dorsal. Along 

 each hind and lower edge of body scales, following rows, oblique 

 dusky line, about 17 to 20 in number; these extend from base of 

 spinous dorsal and dark crescent of soft dorsal till little below level 

 of pectoral. Iris dark brown. Brown band extends from near ends 

 of last dorsal spines to bases of last soft rays, broadening little below, 

 also 2 others, narrower extend more or less parallel on outer portion 

 of same fin. Transverse dark band on last anal rays medially, also 

 another at caudal base. Brownish subterminal band on caudal, 

 edge of fin v.'hitish and front of dark band with dark brown dividing 

 line. Paired fins pale. 



East Indies and Melanesia. This species is readily distinguished 

 from Cfiaetodon lineolatus by its arrangement of the ocular band 

 above which on predorsal is lunar dark blotch medially. Also the 

 dark crescent at the soft dorsal base is not continued on the anal 

 base; the presence of 3 dark lines on the soft dorsal and a dark band 

 at the caudal base are other features of distinction.
