52 PHILIPPINE POMACENTRID^E 



Dorsal XIII, 13 or 14; anal II, 13 or 14; scales in lateral 

 series 26 ; with tubules 16 to 19 ; between lateral line and origin 

 of dorsal 4; between lateral line and vent 10. 



Anterior profile rounded, body oblong, depth 1.9 to 2 in 

 length; head 3 to 3.4; depth of caudal peduncle 6.4 to 6.7. In- 

 terorbital space strongly convex, 2.8 to 3 in length of head ; snout 

 and maxillary about equal in length, each slightly shorter than 

 diameter of eye, which is 2.6 to 3.3 in head. Mouth small, slight- 

 ly oblique; jaws equal; maxillary ending posteriorly below an- 

 terior margin of orbit; teeth in a single row in each jaw. Or- 

 bital ring above angle of mouth less than half diameter of eye, 

 its outer edge denticulated, the first tooth enlarged and separated 

 from the rest by a notch ; opercle with a single spine at its hind 

 margin. 



Orbital ring naked; scales on top of head extending to nos- 

 trils. Dorsal spines increasing in height posteriorly, the last 

 one as high as second anal spine. Soft dorsal and anal, angular, 

 about equal in height; pectoral and ventral of the same length, 

 both extending to origin of anal ; caudal emarginate, the lobes 

 pointed. 



Ground color in alcohol blackish brown, lighter on the lower 

 parts; pectoral fin whitish with a large black spot completely 

 covering its base and axil ; the rest of the fins colored similarly 

 as body; spinous dorsal with a black margin. 



Of this species I have examined in the Bureau of Science 

 Collection fourteen specimens, 47 to 78 millimeters long, from 

 Cabalian, Leyte; and Tambagaan, Bungau, Sibutu, and Sitankai 

 Islands, Sulu Archipelago; also a cotype, 61 millimeters long, 

 collected by C. J. Pierson at Bacon, Sorsogon. The smallest 

 of the specimens, taken at Cabalian in May, 1921, is a female 

 in near-breeding condition. 



I have also examined another cotype of this species in the 

 museum of Stanford University. Of the other cotypes there is 

 one each at the Philadelphia Academy of National Sciences Mu- 

 seum, the United States National Museum, and the Indiana 

 University Museum. The type, No. 55919, is in the United 

 States National Museum.
