gg PHILIPPINE POMACENTRID^E 



Calapan, are ripe females ; two, 55 and 61 millimeters, collected 

 January, 1921, are ripe males; 3 from Puerto Galera, 54 to 57 

 millimeters, March to May, 1912, are ripe females. Four of the 

 specimens from Malampaya Sound and Zamboanga, measuring 

 from 67.5 to 100 millimeters in length, and taken in October, 

 1910, and June, 1925, respectively, are females about ready to 

 spawn. It is also interesting to note that a ripe female, 65 mil- 

 limeters long, was collected in February, 1922, at Lake Taal, 

 which is a fresh-water lake. 



This species has been recorded before in the Philippines from 

 Bohol by Cartier; from Bacon by Evermann and Seale; from 

 Cavite by Jordan and Seale and by Jordan and Richardson ; and 

 from Sanguisiapo, Sulu Archipelago, by Weber. The specimens 

 constitute an interesting series and show every intermediate 

 variety in form and color. The chief character, upon which 

 this species is based, is the presence of three black spots; 

 namely, one above the operculum, another on top of the tail, 

 and a third on the anterior dorsal rays and partly on the pos- 

 terior dorsal spines. Pomacentrus dimidiatus Bleeker, for ex- 

 ample, represents a stage in this series in which the dorsal ocellus 

 is small and confined to the last dorsal spine and the first two or 

 three dorsal rays. 



This species is very common in the Indo-Pacific regions from 

 the Red Sea and the east coast of Africa to the South Sea 

 islands.
