Ground color of alcoholic specimens blackish, with two large 

 pearl white spots; one, which is indistinct or absent in older 

 specimens, on top of head; the other, which disappears with

 gidor; Calapan, Mindoro; Tablas Island; Puerto Princesa, Pa- 

 lawan; Cagayan de Misamis and Zamboanga, Mindanao; and

Ten living specimens at the Bureau of Science aquarium are 

 dusky purplish, with a dark edge on each scale and brassy re- 

 flection below; there is a pearl white spot on top of head and 

 another on lateral line on each side of body; soft dorsal and 

 anal are blackish, while the spinous portions and the other
