Abudefduf sordidus JORDAN and SEALE, Bull. U. S. Bur. Fisheries. 25 

 (1906) 284; JORDAN and JORDAN, Mem. Carnegie Mus. 10 (1922) 68. 



Dorsal XIII, 13 to 15; anal II, 12 to 15; scales in lateral 

 series 26 ; with tubules 21 or 22 ; between lateral line and origin 

 of dorsal 5 ; between lateral line and vent 14. 



Body deep and much compressed, With the dorsal outline 

 deeper than ventral ; greatest depth of body at origin of dorsal 

 fin, 1.8 to 1.9 in length ; head 2.6 to 3 ; depth of caudal peduncle 

 5.2 to 5.3. Interorbital space 3 to 3.4 in length of head and 

 as wide as length of either snout or maxillary ; the large, round 

 eye 2.7 to 2.8 in head. Mouth almost horizontal; teeth very 

 narrow and slender, uni serial in each jaw. Gill rakers 7 + 17 

 on first arch. Orbital ring very narrow; posterior margin of 

 opercle with two flat spines. 



Scales on top of head advancing as far as front margin of 

 orbit, leaving a naked space from there to tip of snout ; no scales 

 on orbital ring and edges of preopercle. Fourth to eighth dor- 

 sal spines highest, last dorsal spine higher than preceding one. 

 Vertical fins obtusely rounded; caudal deeply forked; pectoral 

 ending above anus; ventral extending to base of second anal 

 spine, its first ray filamentous. 



Color in alcohol yellowish brown, with six blackish, rather 

 indistinct transverse bands which are much wider than the inter- 

 spaces between them; the first band descending from origin of 

 dorsal fin; the next three from the spinous dorsal; the fifth 

 below anterior rays of dorsal fin; the last one across caudal 

 peduncle, with its upper portion in the form of a large black 

 spot., A black spot superiorly at base of pectoral and some 

 minute dark spots scattered all over body. Anterior portion 

 of spinous dorsal black ; outer rays of ventral and of other fins 

 dusky. 



Of this well-marked species I have examined thirteen exam- 

 ples, 21 to 50 millimeters long, taken at Luna and Balaoan, 

 La Union; Puerto Galera, Mindoro; Camiguin Island, Cagayan 

 Province ; and Bungau Island, Sulu Archipelago. The presence 

 of a large black spot on the tail and of another on each anterior 

 dorsal spine distinguishes the species from Abudefduf septem- 

 fasciatiis. 



This species ranges from the Red Sea and east coast of Africa 

 eastward to Samoa and Hawaii and northward to China, For- 

 mosa, and Okinawa Islands.
