Abudefduf coracinus SEALE, Philip. Journ. Sci. | A 4 (1909) 521, 

 pi. 13. 



Dorsal XIII, 13 ; anal II, 13 ; scales in lateral series 26 ; with 

 tubules 18 ; between lateral line and origin of dorsal 4 ; between 

 lateral line and vent 11. 



Body markedly deep and compressed, its depth contained 1.9 

 to 2 in length; ventral outline of body deeper than dorsal; 

 anterior dorsal profile from tip of snout to origin of dorsal very 

 oblique and slightly convex; head 3.2 to 3.4 in length of body; 

 depth of caudal peduncle 5.5 to 5.7. Interorbital space strongly 

 arched, wider than length of snout, 2.6 to 2.7 in head; eye 

 round, small, its diameter 3 to 3.8 ; maxillary 2.9 to 3.3 in length 

 of head and about as long as the rounded snout, which is 

 horizontally in front of inferior border of orbit. Mouth small, 

 oblique, jaws equal ; maxillary not reaching anterior margin of 

 eye; teeth in a single series, with rounded tips. Gill rakers 

 on first arch 22. Preorbital above angle of mouth nearly half 

 as wide as interorbital. 



Body covered with large, weakly ctenoid scales. Snout naked 

 below and in front of nostrils ; orbital ring also naked. Dorsal 

 spines increasing in height posteriorly, the last one 1.7 to 1.8 

 in length of head. Soft dorsal and anal rounded, their middle 

 rays highest ; caudal scarcely emarginate, with the lobes rounded ; 

 pectoral rounded, 1.8 to 2 in depth of body, its tip within two 

 scales from vent; ventral extending to vent, with the outer 

 ray produced. 



According to Seale the color of this fish in life is uniform 

 dark brown or blackish. Its color in alcohol is blackish brown ; 

 a blackish spot at axil of pectoral. 



Here described from the type and three other specimens, 

 measuring 58 to 99 millimeters long. The type was collected 

 at Sitankai Island, and the others were collected at Sibutu Island, 

 both in the Sulu Archipelago. 



In the general form of the body and the relative size of the 

 scales, this species is nearest to Abudefduf rhomcdeus Snyder, 

 but differs from it in having the orbital ring naked.
