have been found in Mindanao. Again, the genus Zosterornis 

 is represented by four species in Luzon, but by only two in 

 Mindanao, while Luzon has produced two species of Oriolus 

 (0. isabellce and O. albiloris) which have no known represen- 

 tatives in the southern island. It must, however, be remem- 

 bered that the greater part of the highlands of Mindanao 

 is still untouched. 



Mr. Goodfellow's first visit to Mindanao was made in 

 1903, when he landed at Davao on the south-east coast and 

 ascended the Apo Volcano. His journey was undertaken 

 largely with the object of obtaining living examples of new 

 or little-known birds ; but he also made a small collection 

 of skins, which subsequently found its way to the Tring 

 Museum, and the novelties of which were described bv 

 Dr. Hartert {cf. Bull. B. O. C. xiv. no. c. pp. 10-15). This 

 collection proved of such interest that Mr. Rothschild 

 shortly after called the attention of the well-known collector, 

 Mr. Waterstradt, to Mt. Apo, and the latter discovered there 

 several additional new species {cf. Bull. B. O. C. xiv. no. cvi. 

 p. 71, and no. cvii. pp. 79, 80). 



Meanwhile the Americans had not been idle, and the 

 novelties collected by the various members of the Philippine 

 Scientific Association have been described by Major Mearns 

 [cf. Proc. Biol. Soc. Washington, xviii. pp. 1-8, 73, and 

 83-90 (1905)]. 



Finally, as already stated, in 1905 Mr. Goodfellow again 

 visited his collecting-ground on the Apo Volcano, and pro- 

 cured a large series of birds, the subject of the present 

 memoir ; and though many of the more remarkable species 

 in this collection had been already described by Dr. Hartert, 

 Mr. Rothschild, and Major Mearns, seven additional new 

 species were discovered, viz. : — 



Sarcops melanonotus, Ptricrocotus johnstonice, Rh'momtjias 

 goodfellowi, Chrysucolaptes montanus, Ceyx goodfcllowi, 

 Pseudoptynx mindanensis, and Ptilocolpa mindanensis. 



No less than nineteen species represented in the present 

 collection are new to the British Museum, viz.: —
