(Cebu). 



Depth 2K to 2^; head 33/^ to 3^, width 1^ to 1^. Snout 

 3^ to 4; eye 2 3^ to 3, greater than snout or mterorbital; maxillary- 

 reaches eye, 334 to 33^ in head; interorbital 3 to 334, broadly convex. 

 Gill rakers 6 + 16, lanceolate, long. 



Tubes in lateral line 13 to 16, pores in straight section 7 or 8+2; 

 2 or 3 scales above lateral line to spinous dorsal origin, 8 below, 

 15 or 16 predorsal; 4 rows of cheek scales of which uppermost on 

 infraorbital. Scales with 7 to 9 basal radiating striae; apical denticles 

 78 to 84, with 2 transverse series of basal elements; circuli very fine. 



D. XIII, 10, I to 12, I, fifth spine 1^ to 2^ in head, fifth ray 

 13^ to 1%; A. II, 11, I or 12, i, second spine 1% to 1^, fifth ray 134 

 to 1%; least depth of caudal peduncle 1^ to 23^; pectoral 1 to 13^; 

 caudal 2% to 334 in combined head and body, deeply emarginate; 

 ventral 2 5^ to 33^. 



Pale brown generally, little paler below, each scale with grayish 

 basal blotch or bar. Blue gray line on side of snout to eye. Each 

 scale of cheek with blue gray basal spot, also predorsal, chest, breast, 

 and body along bases of dorsals and anals with blue spots or dots. 

 Also some examples with blue gray blotches of large size on scales of 

 caudal peduncle above. Iris brown. Fins all pale, spinous dorsal 

 and anal usually with some brown. A large black blotch at bases of 

 last 4 dorsal spines and extended below slightly on back. Anal 

 papilla black. Paired fins pale or yellowish. 



East Indies to Japan. A striking species, suggestive of Abudefduf 

 leucozona, with the black ocellus at last spines of dorsal. A. leucozona 

 differs in the presence of a whitish vertical band on the body from 

 the front of the spinous dorsal. 



There is little doubt but that Cartier's Glyphidodon mutabilis is 

 the present species. Though he gives the D. XIII, 13, A. II, 14 and 

 the scales 25 his examples were 45 to 75 mm. Bleeker has given the 

 D. XIII, 15 or 16, A. II, 13 or 14 and the scales 28, but his examples 

 were 58 to 150 mm. long. The presence of but 2 or 3 more soft rays 

 is hardly a specific difference.
