FISHES OF THE PHILIPPINE ISLANDS AND ADJACENT SEAS 387 



Numerous small spinules on snout tip above and close to antero- 

 lateral disk edge in posterior half only; 4 thorns before and 3 be- 

 hind eye; row of 5 median vertebral spines over branchial region; 

 between ocellus and pectoral edge group of lanceolate denticles 

 pointing inward; whole lower surface of snout covered with fine 

 denticles; 3 somewhat irregular rows of spines on tail above and its 

 sides spiny, below smooth. 



Hind dorsal little larger, 2% in snout, interdorsal ■% first dorsal 

 length; caudal small, low; pectorals form rhomboidal disk, front 

 edges slightly undulate, lateral and hind angles broadly rounded. 



Uniform brown above, with dark ocellus surrounded by paler 

 ring at postero-median base of each pectoral. Uniform white 

 below, tail dark mottled below. Length, 360 mm., male. (Lloyd.) 



Gulf of Aden. Lloyd suggests Raia powelli may be the female; 

 also a female from Travancore appears intermediate.
