 lower flank which are white ; shafts of under tail-coverts dark brown. A 

 male from Palawan measures: Length, 239; wing, 203; tail, 67; ex- 

 posed culmen, 10; tarsus, 17. A female from Culion measures: Length, 

 229; wing, 200; tail, 68; exposed culmen, 9; tarsus, 16. 



Worcester and Celestino collected a large series of giant swifts in 

 Culion and Palawan. I have seen large swifts in Benguet Province and 

 in Calayan, and Worcester observed a large flock in northern Luzon which 

 may have been either C. gigantea or C. dubia.

Basilan (M earns) ; Negros (Keay). Celebes. 



Adult. "Deep steel-blue, back and rump with purple gloss; two white 

 spots on the sides of the forehead; sides of the abdomen and under tail- 

 coverts white. In size similar to C. gigantea" (Hartert.) 



Clarke gives the following notes on a specimen obtained in Negros: 

 "The back is an admixture of dark brown, or brownish black, and deep 

 steel-blue, each feather having a broad subterminal band of blue with an 

 edging of dark brown, which conceals the blue to a considerable extent, 

 so that the brown predominates. The tail and secondaries are glossed 

 with green and blue in about equal proportions. Length, 241 ; wing, 216 ; 

 tail, 73; tarsus, 18." 



"Female. A specimen in the Sarasin Collection marked ' $ juv.' (but 

 we can not see any signs of immaturity) answers to Mr. Hartert's 

 description of the species, except that the lores are reddish brown not 

 white. Wing, 208; tail, 63; tarsus, 16; bill from nostril, 6." (Meyer 

 and Wiglesworth.) 



Mearns gives the following measurements of two males from Basilan : 

 "Length, 240, 255 ; wing, 215 ; tail, 75 ; bill from frontal feathers (chord), 

 8.5, 9.6; bill from anterior margin of nostril, 6.1, 7.1; tarsus, 19, 20; 

 middle toe with claw, 22.5." 



But six specimens of this large swift are known, three from Celebes, 

 one from Negros, and two from Basilan.
