94 PHILIPPINE POMACENTRHXE 



dorsal dusky on outer portion ; pectoral whitish, with a blackish 

 spot across its base; anal and ventrals dusky. 



The above account is from seven examples, 43 to 65 milli- 

 meters long, taken at Tagbilaran, Bohol; Canigaran, Palawan; 

 and Tambagaan, South Ubian, Bungau, and Sitankai Islands, 

 Sulu Archipelago. Two specimens from Guam, which I have 

 examined, in the Bureau of Science collection, agree in every 

 respect with the Philippine representatives. 



This species has not been noted previously from the Philip- 

 pines. It occurs in almost all parts of the Indo-Australasian 

 Archipelago, whence it ranges eastward to Samoa. 



Genus CHRYSIPTERA Swainson 



Chrysiptera SWAINSON, Nat. Hist. Fish. 2 (1839) ; azureus; not 

 Chrysoptera Latreille (1885), a genus of Lepidoptera. 



Paraglyphidodon BLEEKER, Nat. Verb. Holl. Maats. Wet. 2 (1877) 

 116; bonang. 



Glyphidodontops BLEEKER, Nat. Verb. Holl. Maats. Wet. 2 (1877) 

 128; cyaneiis=:azureiM. 



Body oblong or ovate, deep or elongate. Scales large or 

 moderate in size, about 26 or less in longitudinal series; lateral 

 line interrupted before the end of soft dorsal fin. Teeth in a 

 double series, compressed, with entire edges. A single dorsal 

 fin with 13 spines. Orbital ring and all the opercular bones 

 entire. 



Under Chrysiptera Bleeker recognizes two genera: Paragly- 

 phidodon, with the body rather deep, teeth more or less rounded, 

 and the snout scaly ; and Glyphidodontops, with the body oblong 

 or slightly elongate, the teeth more or less truncate, and the 

 snout naked. It differs from Abudefduf in the presence of two 

 rows of teeth. 



Thirteen species of this genus are known to occur in the 

 Philippines ; it is widely distributed from the Red Sea and. the 

 east coast of Africa to Polynesia.
