ABUDEFDUP 81 



dorsal continued on the anterior rays; a dark spot superiorly 

 at base of pectoral. 



Here described from sixteen examples, 30 to 114 millimeters 

 long, collected at Taylon and Tanao Islands, Camarines Norte; 

 San Miguel Bay, Camarines Sur ; Halsey Harbor, Culion Island ; 

 Puerto Princesa, Palawan; Placer and Cagayan de Misamis, 

 Mindanao; and Sitankai Island, Sulu Archipelago. The spec- 

 imens mentioned above are identical with two examples from 

 Hongkong, which are now in the Bureau of Science collection. 



This species differs from Abudefduf septemfasciatus in having 

 narrower bands and a dark blotch at the base of the caudal fin. 

 It has not been recorded from the Philippines heretofore, is 

 abundant in the Gulf of Bengal and on the coast of the Anda- 

 mans, and is rarely known from the Malay Archipelago.
