 rictal bristles much longer, reaching nearly or quite to end of bill; 

 feathers of crown not stiffened; tarsus much less distinctly scutel- 

 late. Similar to Rhipidura Vigors and Horsfield, but tail not de- 

 cidedly longer than wing, and only rounded, not strongly graduated; 

 tarsus less distmctly scutellate; rictal bristles relatively shorter, 

 not reaching appreciably beyond tip of bill.

tt. Pileum lighter, brighter, more bluish; light-blue eyebrow and frontal line broader. 



Cyanonympha superciliaris superciliaris. 

 "^ Pileum darker, duller, less bluish; light-blue eyebrow and frontal line more narrow. 



Cyanonympha superciliaris samarensis. 



CYANONYMPHA SUPERCILIARIS SUPERCILIARIS (Sharpe). 



Hypothymis superciliaris Sharpe, Trans. Linn. Soc. Lond., ser. 2, vol. 1, pt. 6, 

 1877, p. 326 (Isabella de Basilan, Basilan Island, Philippine Islands). 



Chars, sp. — Upper parts of male deep verditer blue, the i>ileum 

 indigo blue, the forehead and a supraloral line bright azure blue; 

 wmgs and tail fuscous, margined with cobalt or purplish indigo 

 blue; throat and breast purplish china blue; posterior lower parts 

 white washed with blue. Female similar to male, but of a rather 

 lighter, slightly more greenish blue. 



Measurements. — Seven males: Wing, 73-81 (average, 78.1); tail, 

 75.5-83.5 (average, 77.9); exposed culmen, 11-12 (average, 11.6); 

 tareus, 15.5-16.5 (average, 15.9) mm. Six females: Wing, 72-78.5 

 (average, 74,9); tail, 73.5-79 (average, 76.5); exposed culmen, 

 11-12 (average, 11.6); tarsus, 15-16 (average, 15.5) mm. 



Type-locality. — Isabella de Basilan, Basilan Island, Philippine 

 Islands. 



Geographical distribution. — Islands of Basilan and Mindanao, Pliil- 

 ippme Archipelago. 



Specimens from the island of Basilan seem to average somewhat 

 lighter, more greenish blue above than those from Mmdanao, but 

 this is not sufficient to warrant any subspecific separation, at least 

 with the material at our present disposal. There is apparently very 

 little sexual difference in this species, aside from the inferior size of 

 the female.
