useless boys, was entirely dependent on liis own efforts. 

 Having reached the extreme north of the island, he made his 

 way to the mountains on the nortli-east coast. The country 

 was mostly flat or undulating and covered with coarse grass. 

 When the hills were reached they were found to be almost 

 impossible collecting- grounds, being covered with thick 

 bamboo- growth intermingled with very high trees. Birds 

 were very scarce, and this was the reason that so few specimens 

 were procured. In addition to the birds a few small 

 mammals, including a new bat and a new mouse, were 

 obtained, also some reptiles (among them a new lizard), 

 batrachians, and fishes, while insects, especially beetles, were 

 numerous. 



In returning from Isabella Mr. Whitehead rode over the 

 mountains across the middle of North Luzon to Manila, 

 which he reached in eleven days. Immediately on arriving 

 at the capital he was seized with a severe attack of fever and 

 liver-derangement, which kept him in that most unhealthy 

 town for some time ; but when I last had news from him he 

 was located on the south-east coast, enjoying excellent health 

 and making a large collection. The day after he wrote (7th 

 September) he was to sail across to the island of Catanduanes 

 in a small boat for a month^s collecting. He expected to be 

 again in Manila by the middle of October, when he intended 

 to despatch his collections, which appear from his letters to 

 contain many interesting birds.

At first glance the adult female which forms the type of 

 this very distinct species might be mistaken for the Oriolus 

 albiloris, Grant, described in the last volume of 'The Ibis,^ 

 1894, p. 504. The latter species was also founded on a
