Birds of Palawan. 43 



10. Pernis ptilonorhynchus. M. 

 Only one specimen procured. 



11. Falco peregrinus. *. 



A winter migrant, arriving about the middle of September. 



12. Hypotriorchis severus. #. 



I met with this little Hawk several times on the sea-coast, 

 and often started before daylight to a point on the coast 

 where it used to pass,, but unfortunately never got within 

 shot. 



13. Circus spilonotus. *. 



I saw a white Harrier, which was probably of this species 

 (as it is very common in Borneo), on the 12th September. 



14. Pandion haliaetus. *. 

 One or two seen on the coast. 



15. Baza leucopais. f- (Plate II.) 

 Baza leucopias, Sharpe, Ibis, 1888, p. 195. 



If this species is confined to Palawan, it will be interesting 

 to find a strong- winged bird keeping to such a limited area. 

 I rather expect it will be met with in the Philippines, which 

 are so near to the eastern parts of Palawan. 



Mr. Sharpe begs me to state that his name of leucopais 

 (Xevtcos, white ; iral<i, a child) was misprinted leucopias, and 

 he wishes it changed back to his original spelling. 



16. Syrnium whiteheadi. %. 



The loud " hoo, hoo," of this fine Owl first attracted my 

 attention, I remember, one evening when returning to the 

 shed under which we lived, being quite startled by the loudness 

 of its note. I several times saw these birds during the day 

 in the swamps, but they had probably been disturbed from 

 the forests close at hand. On the mountains inland I heard 

 several. 



Orbit pink; eye and bill black. 



This is the Syrnium wiepkeni of Blasius, who described 

 Platen's Palawan collection {cf. Ibis, 1888, p. 372). As 

 to the question of priority of names, I have written to
