 noticeably lighter, being light seal brown, each feather with a 

 subterminal, more or less concealed area, or band, of bluish violet; 

 head and body shot with bluish violet gloss, strongest on chin, 

 throat, breast, and sides of head and neck; a large white patch on 

 each side between nostril and antrose feathers in front of eye; 

 crissum white, each feather blackish brown at its base, the longest 

 feathers with edges also blackish brown except near tip ;^ extending 

 diagonally upward and forward on each flank a wide white stripe 

 connected with the white crissum behind as in Chcetura gigantea; 

 exposed edges of wing feathers black, inner webs of primaries 

 largely light brown; inner webs of alula and primary and secondary 

 coverts shot with greenish blue gloss, this gloss also on outer web 

 of primaries where hidden by primary coverts; tertiaries greenish 

 blue ; lining of wing brown, each feather bordered with dirty white 

 which has its greatest extent on the innermost feather; axillaries 

 dark brown, shot with bluish violet gloss; exposed portion of tail

Cotype. — Adult female, Xo. 4718, Government Laboratories Col- 

 lection; Mindoro, P. I., March 18, 1905; McGregor et aliae. 

 Length in flesh, 9.2 inches; wing, 8.57; tail (spines worn), 2.52; 

 bill from nostril, 0.30; tarsus, 0.72. 



The few words, without measurements, in Catalogue of Birds, 

 XVI, p. 476, scarcely apply to the Mindoro species for Hartert 

 says of celehensis: "In size similar to C. gigantea/' whereas C 

 diihia is decidedly larger than gigantea; Clarke's- measurements 

 of the Negros specimen certainly agree much better with our bird, 

 but neither of these writers makes any mention of white wing 

 lining in C celehensis, a character very noticeable in C. dubia. 



This species was seen almost daily flying high over the clearing 

 at Chicago and I also observed large swifts near Balete. The two 

 specimens obtained by us were killed at the former locality. 



Sumiculus velutinus Sharpe. 



Several specimens of this little black cuckoo were killed at Balete. 



^ In the female specimen before me the two longest undertail coverts have 

 the shaft blackish brown to the tip.
