40 PHILIPPINE POMACENTRUXE 



head; diameter of the small, circular eye 3.3 to 4.3 or shorter 

 than width of preorbital at angle of mouth in large specimens ; 

 the long, slightly pointed snout 2.5 to 3, longer than maxillary, 

 which is contained 3.1 to 3.6 in head. Cleft of mouth oblique, 

 jaws even, tip of snout more inferior than lower margin of 

 eye; teeth in two rows, those in outer row short and having 

 slightly emarginate edges. Lower edge of suborbital and poste- 

 rior edge of preopercle strongly serrated ; opercle armed behind* 

 with two sharp spines. 



Head naked on snout in front of nostrils and on edges of 

 preopercle; base of vertical fins with a high sheath of scales. 

 The last three dorsal spines almost equal in height. Middle 

 rays of the vertical fins produced into a point; caudal emar- 

 ginate, with the lobes broad and rounded; pectoral rounded, its 

 tip within two scales from the point above anus; outer ray of 

 ventral filamentous, ending behind at anus. 



Brown or violet-black in alcohol, with scattered dots on head 

 and a whitish spot on each scale of trunk, the spots on trunk 

 forming more or less longitudinal series. In many of the ex- 

 amples a large dusky blotch is present at base and axil of the soft 

 dorsal fin, and in the very young it is in the form of an -ocellus 

 edged anteriorly with bluish white. Pectoral yellowish, having 

 a dark axillary spot which is absent in some specimens ; all the 

 other fins dusky. 



Here described from forty-two examples, 20.5 to 97 milli- 

 meters long, collected at Puerto Galera and Calapan, Mindoro; 

 Bulan, Sorsogon ; Canigaran, Palawan ; and South Ubian, Sibutu, 

 and Sitankai Islands, Sulu Archipelago. This species has been 

 previously recorded in the Philippines by Jordan and Seale from 

 Negros Island. 



In all the specimens examined the number of dorsal spines is 

 twelve. I have examined also in the Bureau of Science collec- 

 tion some examples obtained by Seale at Guam> which are much 

 lighter in coloration than those from the Philippines. 



This species occurs from the Red Sea and east coast of Africa 

 throughout the tropical Indo-Pacific seas to the islands of the 

 South Seas.
