A fine male example of this rare bird, the Philippine Hawk- 

 Eagle, from Cape Engano. 



4. Spilornis holospilus (Vig.) ; Grant, Ibis, 1895, 

 p. 251. 



An adult female o£ this fine Serpent-Eagle came in the 

 second half of the Lepanto collection, but arrived too late to 

 be added to my last list in the October ' Ibis,' 1895. 



From Cape Engano we have received an immature female, 

 which has the head and upper mantle whitish bufiF, with 

 brown shaft-spots ; there is the beginning of a short deep 

 black superciliary band extending above the eye, while a few 

 feathers of a more adult plumage are beginning to make 

 their appearance on the occiput ; these are brownish red, with 

 a wide subterminal black tip. (The appearance of this black 

 eyebrow-stripe is very puzzling, as it does not appear in the 

 adult plumage ; it may be part of an intermediate plumage 

 or fade with age and wear to the dark brown of the adult.) 

 General colour above brown, with irregular, ill-defined reddish- 

 white spots on either web ; tail dark brown, with two wide 

 brownish-white bands across the terminal half; chin and 

 throat whitish buif ; sides of the head and underparts pale 

 buff, with brownish-red shaft-stripes, widest on the terminal 

 half ; thighs buff, with wide chestnut middles, constricted at 

 intervals, so as to form ill-defined buff spots down the sides 

 of the feathers, one or two half-grown adult feathers on the 

 left thigh. 



Wing 15'2 inches, tail 10*7, tarsus 3*4. 



Although somewhat peculiar in plumage and large in size, 

 I have no hesitation in referring this specimen to S. holo- 

 spilus, and Mr. Whitehead shares the same opinion.

The Philippine Hawk-Owl was again found in the neigh- 

 bourhood of Cape Engano, where several adult birds and an 

 immature female were collected. 



The immature female differs from the adult in having the
