were new to science; namely, Planesticus mindorensis (Grant) 
and Zonophaps mindorensis (Whitehead) .” 
In 1906 Mearns headed an expedition that pushed to the sum- 
mit of Mount Halcon.”* The results in birds were disappointing, 
for this party, like Whitehead’s, encountered incessant rain at 
high altitudes. Mearns has described the following from Min- 
doro: Cyornis mindorensis, from 150 meters’ altitude; Zos- 
terops halconensis, from 1,400 meters’ altitude; and Dicrurus 
balicassius mindorensis, from the lowlands. Probably none of 
these is an exclusively highland species. 
In Negros Whitehead collected only two new highland species; 
namely, Planesticus nigrorum (Grant) and Brachypteryx brun- 
neiceps Grant.” 
Mindanao contains lofty mountains on a scale similar to Luzon, 
and many striking species have been brought to light by Good- 
fellow, Waterstradt, and Mearns. Further exploration, espe- 
cially of the higher mountains, will doubtless result in additions 
to the known bird fauna of Mindanao. Most of the following 
species are confined to the highlands of Mindanao: 
Trichoglossus johnstonie Hartert. Mount Apo. 
Prioniturus waterstradti Rothschild. Mount Apo, at 900 to 2,500 meters. 
Prioniturus malindangensis Mearns. Mount Lebo, a spur of Mount 
Malindang, at 1,500 meters. 
Chrysocolaptes montanus Grant. A partially alpine form, also found 
on the coast. 
Chrysocolaptes malindangensis Mearns. Mount Malindang, at 1,800 
meters. 
Muscicapula montigena Mearns. Mount Apo, at 1,800 meters. 
Rhipidura nigrocinnamomea Hartert. Mount Apo. 
Rhipidura hutchinsoni Mearns. Mount Malindang, at 1,200 to 2,700 
meters. 
Rhinomyias goodfellowi Grant. Mount Apo. 
Rhinomyias mindanensis Mearns. Mindanao (in general?). 
Cryptolopha mindanensis Hartert. Mount Apo. 
Cryptolopha malindangensis Mearns. Mount Malindang, at 2,700 meters. 
Eumyias nigriloris (Hartert). Mount Apo. 
Malindangia megregori Mearns. Mount Malindang, at 1,200 to 2,700 
meters. 
Pericrocotus johnstonie Grant. Probably a lowland species. 
Pseudotharrhaleus unicolor Hartert. Mount Apo. 
Pseudotharrhaleus malindangensis Mearns. Mount Malindang, at 2,700 
meters. 
Macronous montanus Mearns. Pantar, at 610 meters; and Mount Apo, 
at 1,220 meters.
