POMACENTRUS 63 



of preopercle strongly serrated; opercle armed behind with 

 two flat spines. 



Area between nostrils and tip of snout naked; orbital and 

 posterior edge of preopercle also naked. The middle dorsal 

 spines highest. Soft vertical fins slightly rounded ; caudal emar- 

 ginate, with the lobes rounded ; pectoral ending above anal open- 

 ing, ventral extending beyond it. 



Brownish in alcohol, with a pearl-colored vertical band de- 

 scending below the third, fourth, and fifth dorsal spines, and 

 with a second pearl white crossband through the soft vertical 

 fins in very young examples. A large blackish blotch on the 

 ninth, tenth, and eleventh dorsal spines near base. Spinous 

 dorsal narrowly edged with black; ventral and anal dusky; the 

 other fins yellowish. A dark round spot superiorly on opercle; 

 a short bluish white line in front of eye and another immediately 

 under orbit ; pearly white dots scattered on cheek ; an indistinct 

 light spot or streak on each scale. 



Here described from eight specimens, 21 to 38.5 millimeters 

 long, coming from Cuyo; Samal Island, Mindanao; and Sibutu 

 and Sitankai Islands, Sulu Archipelago. A careful examination 

 of Pomacentrus suluensis Scale shows that it is only the young 

 of the present species, with the serration of the suborbital still 

 undeveloped. 



This species is found in small numbers in the Indo-Australa- 

 sian Archipelago and in the islands of the South Seas. Jordan 

 and Scale have recorded it from the islands of Woodlark, Fate, 

 and New Hebrides.
