In the preceding consideration of the forest species of Philip- 
pine birds I have tried to indicate that many of the lowland 
forest genera persist to considerable elevations, in some cases 
without change of species. On the other hand it has been noticed 
that in Luzon, above about 1,200 meters’ altitude, the lowland 
species in several genera are replaced by other, more or less dis- 
tinct, species; for example, in Prioniturrts, Callisitta, Dicseum, 
Leucotreron (subgenus N eoleucotreron) , Pitta, Otus, Lanius, 
Hyloterpe, and Rhinomyias. 
The highlands also yield genera that are unrepresented in the 
lowlands. Among these are Pseudotharrhaleus, Brachypteryx, 
Planesticus, Chaimarr ornis, Tribura, Loxia, Malindangia, Good- 
fellowia, Hypocryptadius, Leonardina, and Pyrrhula. Some of 
these genera are found only in the Philippine Islands, while the 
others are represented in neighboring and distant parts of the 
world. 
LOCAL DISTRIBUTION OF ENDEMIC PHILIPPINE BIRDS 
If we consider the distribution of the endemic species of Phil- 
ippine birds we find that certain species occur in nearly all the 
islands of the Archipelago. Corvus philippinus, Pycnonotus 
goiavier, and Oriolus acrorhyhchus are example of these, and 
such species are usually abundant. Other species are the sole 
members of their respective genera and are confined to single 
islands ; such are Dasycrotapha speciosa, Malindangia mcgregori, 
and Goodfellowia miranda.
