16,4 McGregor: Some Features of the Philippine Ornis 403 
two of the most remarkable highland species, Pitta kochi Briig- 
gemann and Leucotreron marchei (Oustalet), had been described 
from specimens labeled “Manilla,” but no one seems to have sus- 
pected that these were representatives of a distinct highland 
fauna. 
Whitehead’s first highland collection ** was made in the vi- 
cinity of Trinidad, which marks about the lower limit of the 
pine forest in that region. 
After the Benguet trip Whitehead visited other parts of 
northern Luzon and collected specimens of nearly every species 
of bird that is known from these highlands. In Isabela Prov- 
ince he discovered Zosterornis striatus Grant and Oriolus isa- 
belle Grant.*®* 
On his next trip, although he was very weak and scarcely 
able to eat or to walk because of dysentery, Whitehead pushed to 
the elevated region known as Mount Data where he rediscovered 
the two magnificent species Pitta kochi Briiggemann and Leu- 
cotreron marchei (Oustalet). On this trip he added ten new spe- 
cies to the known fauna of the Philippines, and some of them 
are characteristic of the highlands. Nearly all of the species 
discovered by Whitehead in the highlands have been collected 
since by Worcester, Mearns, or McGregor. 
Scops whiteheadi Grant, Pitta kochi Briiggemann, and Lusci- 
niola seebohmi Grant have not been collected since Whitehead’s 
time. My own work in the vicinity of Baguio and in the mossy 
“ Many of the early specimens came from “Manilla,” but few of them 
were collected in the vicinity of Manila; certainly not these two species, 
for no one has found either of them in the lowlands and no one ever will. 
How the types of these two rare species and no others came out of the 
mountains probably will never be known. 
“See Grant, W. R. O., On the birds of the Philippine Islands. Part 
II. The highlands of north Luzon, 5,000 feet, Ibis VI 6 (1894) 501-522. 
Grant described nineteen new species in this paper, but some of the species 
included in Grant’s paper were collected at lower elevations and near the 
coast, as can be determined by an examination of Whitehead’s notes, Ibis 
VII 5 (1899). For example, under Cinnyris jugularis (vel C. obscurior 
Grant), Whitehead says: “We met with this species as high as 3,000 feet 
in Benguet.” Under Oriolus albiloris he says: “The unique specimen 
obtained was shot in the Benguet mountains at an altitude of 2,000 feet.” 
It is unfortunate that Whitehead’s notes were not published with Grant’s 
reports on the collections. With regard to this Grant says: “We cannot 
help thinking, however, that the delay in publishing these valuable notes, 
which cannot fail to be of the greatest interest, is a mistake, as such 
information would greatly enhance the value of the papers published on 
his collections, which are at present, of necessity, somewhat dry reading, 
dealing, as they do, merely with the birds from a scientific point of view.”
