scales about 2+22 to 25+6; a small black spot, smaller than 

 pupil at base of caudal fin rays on end of lateral line and 

 at end of a narrow longitudinal black streak along axis of body ; 



dark opercular spot Apogon ceramensis Bleeker 



6&. Dorsal fin rays VII-I, 9 or 10 ; anal fin rays II, 8. 



8a. Color pattern not of blackish longitudinal stripes but on side 

 of body four to eight vertical color bars under dorsal fins, 

 sometimes these are rather indistinct ; no teeth on palatines ; 

 opercle with silvery spot, posteriorly ; dorsally and ventrally 

 around this spot is blackish pigment ; a prominent narrow black 

 streak from lower margin of eye backward and downward 

 across cheek ; a dark saddle on caudal peduncle extends from 

 niiddorsal line to below lateral line, but in young this meets 

 its fellow on ventral side of the caudal peduncle; first dorsal 

 spine SVj in second; second 2 times in third ; third longest; pec- 

 toral rays about 13 ; scales 2+25+5 ; gill rakers 6 or 7+18 to 20, 



long and slender Apogon bandanenis Bleeker 



Sb. Color pattern consists of five or six longitudinal blackish color 



streaks on sides of body as follows: (1) A middorsal streak 



divides at origin of spiny dorsal and continues along dorsal 



bases joining again on caudal peduncle; (2) one begins over 



orbit and runs above lateral line along upper part of caudal 



peduncle; (3) median one extends from snout through eye 



along axis of body, more intense black below soft dorsal, and 



again more blackish in front of base of caudal fin rays; (4) 



this one runs below orbit, forms a black opercular blotch and 



another spot on base of pectoral continuing along midventral 



side; (5) from tip of chin across maxillaries through branch- 



iostegals ; (6) along dentaries, joining number 5 on branch- 



iostegals ; soft dorsal and anal fin rays have a black streak 



just above base of fin ; first dorsal spine 2% in second ; second 



2Vf, in third, third longest; pectoral rays 14 or 15; gill rakers 5 



or 6+14 to 16 ; scales 2+24 to 26+5 or 6. 



9a. Color streaks 2 and 4 (above) continue on caudal fin rays, 



second streak has a downward trend toward midposterior tip 



of fin but is interrupted by a light streak above midline of fin ; 



number 4 is the same but is directed dorsally ; number 3 



streak continues to tip of middle caudal fin rays. 



Apogon novemfasciata Cuvier 

 9b. Color streaks do not continue on caudal fin rays. 



Apogon aroubiensis Ilombron and Jacquinot 



4b. The margin below angle of posterior edge of preopercle flexible and 



not serrated. 



10a. Above angle on posterior edge of preopercle stiff and serrated ; caudal 



fin truncate ; dorsal fin rays VI-I, 9 ; anal II, 8 ; pectoral fin rays 



12 or 13 ; scales 2+22 to 25+6 or 7 ; peritoneum duskj% intestine 



light colored ; palatines with teeth ; second doi-sal spine longest. 



11a. Gill rakers 2 or 3+12 or 13; faint color spot silvery or blackish on 



opercle with small patch of black pigment above it ; scales a short 



space in front of posterior edge are pigmented, this most prominent 



in predorsal region and along upper back, body and fins plain 



color otherwise ; sometimes a trace of dark pigment cells along
