5 dorsal rays and membranes whitish, sometimes scarcely paler than 

 rest of fin. Median caudal rays always paler than rest of caudal 

 though variably grayish to whitish, upper and lower lobes greatly 

 contrasted. Pectoral brown. Ventral blackish. Iris brownish- 

 yellow. 



East Indies, Australia, Japan. The dark borders to the upper and 

 lower caudal lobes and the usual whitish blotch at the bases of the 

 last dorsal rays are distinctive. 



The nominal Poniacentrus cyanomos Bleeker was based on a single 

 example 106 mm. long. It appears to represent a mature condition 

 of the present species. We have smaller examples, which in every 

 way agree and which we are unable to separate, due doubtless to 

 different conditions in the preparation. 



The type of Pomacentrus lucosphyms is a large example of the 

 present species. It differs only in its largely black coloration, the 

 outer terminal ends of the ventrals alone contrasted whitish.
