somewhat rounded; interorbital 2% to 3, broadly convex; lower

 7+16, lanceolate, long, slender. 



Tubes in lateral line 16 to 18, pores in straight section 6 to 9+0 

 to 2; 3 scales above lateral line, 8 or 9 below, 17 to 20 predorsal; 4 

 or 5 rows of cheek scales. Scales with 8 or 9 basal radiating striae; 

 apical denticles 77 to 125, with 2 or 3 transverse rows of basal ele-

 1% to 2, sixth ray 1% to II/5, with first and second rays sometimes 

 simple; least depth of caudal peduncle 1% to 2; pectoral 1 to 1^4; 

 ventral 1 ; caudal forked, 2l^ to 3% in combined head and body. 



Body chocolate to neutral brown, base of each scale with pale 

 bluish spot, on head smaller. Blue-gray line from snout tip to eye. 

 Iris neutral brown. Suprascapula with dusky blotch about size 

 of pupil, always smaller than dark basal pectoral blotch. Dorsals 

 neutral dusky, with last half of fin abruptly pale yellowish to 

 white, the dusky of anterior portion reaching back marginally to 

 ends of longest rays. Caudal peduncle and caudal fin largely uni-

East Indies, Japan. A very handsome trim little fish, chiefly 

 noted for the abrupt light hind portion of the dorsal, tail, and cau- 

 dal fin. It differs at once in the uniform yellow caudal from Pom- 

 acentrus taeniurus, though agrees with Abudefduf hankieri in 

 that respect. From the last it may easily be known by the entire 

 pectoral base blackish and the dark area of the soft dorsal extend- 

 ing back to the tips of the longest rays.
