Ch^etura, species. 



Large swifts were seen a few times on both Fuga and Calayan. Dur- 

 ing a heavy rain I saw a party flying low, but to my disgust they all 

 took to the hills before I could come within range. 



Taciiornis infumata (Scl.) ; McGregor, Bull. Phil. Mus., I, p. 5 

 (Ticao). 

 During a recent trip to Anao, Tarlac Province, we were fortunate in 

 killing a bird of this species. A few others were seen, but it was by 

 no means common. This fork-tailed swift is now recorded from Luzon 

 for the first time. 



EUDYNAMIS MINDANENSIS (Linn.). 



Occurs on Calayan in same localities as the following species, but is 

 much less common. The two species are known to the natives as 

 "tu-aoo." Probably occurs on Fuga also, but during our short stop 

 there we got samples of the larger species only. 



There seems to be much variation among the females of this species 

 as stated by Captain Shelley (Cat. Bds., XIX, p. 317). None of our 

 female specimens is barred with white on upper tail coverts and tail as 

 described by Shelley and they are probably young birds. However, that 

 the very young female bird is black there is no doubt, as our series from 

 Calayan contains females in which the black and spotted plumages are 

 variously mixed. For example, a female taken October 2 has seven tail 

 feathers uniform black and three tail feathers black barred with rufous 

 buff. The uniform feathers are evidently of the old plumage. We have 

 others in which the wings and body feathers show similar mixtures. 



Whitehead got one male Eudynamis on Fuga which Grant was unwill- 

 ing to refer to any described species, pointing out, however, that it was 

 larger than E. mindanensis. On Calayan we found both large and small 

 birds of this genus, the large ones being by far the more common. For 

 this species I propose a new name.

 larger, the female more nearly uniform black above and with head more 

 rufous.
