236 Mr. J. Whitehead on Birds 



Abra on our journey to the Lepanto highlands. It was 

 obtained by a mere chance, the native who killed it being 

 under the impression that he had wasted a shot on the 

 common Muscicapa griseisticta, of which this species is a 

 perfect mimic; it was a wonder that the Indian did not 

 throw it away. This Piprisonia, I expect, is a rare bird and 

 easily overlooked, but its range seems to extend over the 

 whole archipelago. In Dr. Worcester's distribution table, 

 Luzon, Mindoro, Cebu, and Mindanao are the islands given 

 in which it has been obtained. 



Iris light hazel; bill light slate-blue; feet dark lead-blue. 



172. CoTiLE SINENSIS (Gray). (Grant, Ibis, 1895, p. 111.) 

 Fairly common on the large rivers of North Luzon. We 



observed numbers entering their nesting-holes in the high 

 banks of the Abra river on our return from Lepanto in the 

 middle of February. Perhaps this Sand-Martin does not 

 range much south of Manila in the Philippines, as it has not 

 been met with in any of the other islands. 



173. HiRUNDo GUTTURALis Scop. (Sharpc, Cat. B. x, 

 p. 134.) 



A winter migrant. Numbers were noticed going north at 

 Cape Engano on the 14th of May. 



174. HiRUNDo JAVANicA Sparrm. (Grant, Ibis, 1891, 

 p. 516 ; 1895, p. 258 and p. 455.) 



A resident of wide distribution in the Philippines and 

 throughout the Malay Archipelago. I once found a pair 

 nesting on a small island in the sea off Cape Engaiio, the 

 nest being attached to a hollowed-out rock. The birds had 

 eggs ; this was on the 17th of May. 



175. HiRUNDo sTRioLATA Boic. (Grant, Ibis, 1894, 

 p. 516.) 



In the mountains of Benguet, at an altitude of 5000 feet, 

 this species was fairly common among some high rocks, 

 where I have little doubt the birds noticed by me were 

 building their nests. In Central North Luzon I noticed 

 large flocks perching on the telegraph-wires which traverse
