forest at Pauai, on Mount Pulog, and on Polis Mountain has 
yielded just one additional novelty, Pihonochilus anthonyi Mc- 
Gregor.®® The discovery of this remarkably distinct species in- 
dicates that there may be yet a few unknown species in this vast, 
elevated area in which no thorough collecting has been done. 
The number of species to be found in the mossy forest in 
Luzon is small, and the number of species confined to it is very 
much smaller. Only twenty-two species were seen near Pauai 
(Haight’s), which is a very favorable locality for birds. The 
following species appear to be confined to the mossy forest: 
Leucotreron marchei (Oustalet). Mount Data and Polis Mountain; rare. 
Pyrrhula leucogenys Grant. Common at Pauai and at other localities 
in the mossy forest. 
Rhinomyias insignis Grant. ' Pauai and Mount Data; rare. 
Pitta kochi Briiggemann. Known only from Mount Data. 
Lusciniola seebohmi Grant. Known only from Mount Data. 
Prionochilus anthonyi McGregor. Known only from Polis Mountain. 
Some of these species may turn up at much lower altitudes. 
Loxia luzoniensis seems to be confined to the pine regions with- 
out regard to altitude. Nearly all of the other species so far 
recorded from the mossy forests of Luzon are known also from 
the broad-leafed forest below ^the pine belt, and many of them 
are abundant in the lowland forests, below 500 meters’ altitude. 
BIRDS OP THE HIGHLANDS OF NORTHERN LUZON 
The following species are all that have been recorded in north- 
ern Luzon from above 1,200 meters’ altitude. 
The list is based on the lists of Whitehead’s collections pub- 
lished by Grant, on Whitehead’s field notes, and on my own pub- 
lished records. From Whitehead’s notes it is clear that some 
of the species included by Grant as coming from the highlands 
were really collected in the lowlands. For example, Oriolus 
alhilorus and 0. isabelUe are common at less than 100 meters’ 
altitude in suitable forest. Some of the other specimens re- 
ported by Grant as coming from “5,000 feet” were undoubtedly 
collected at much lower altitudes. My own experience in the 
Mountain Province as well as in other parts of Luzon has been 
of help in preparing this list. 
Excalf actoria lineata (Scopoli). A characteristic lowland species that 
may be found within the lower limits of the highlands. Recorded by 
Whitehead from 1,200 meters.™

™ The altitudes given by Whitehead in feet have been changed to meters ; 
the odd quantities of less than 50 meters are of no consequence and are 
not recorded.
