Measurements of type:—Wing, 94, tail, 105 ; bill from gape,
26; tarsus, 33 mm. Type:—Adult male from Sodong Gerok,
Idjen Massif, 3,900 feet, near Banjoewangi, Eastern Java,
April 1st, 1916. Very large series examined from the same
vicinity from 1,400 feet to 5,000 feet.
Remarks — Hartert, in a paper on birds from the Ardjuno
has already noticed the differences in the superciliary streak
(Nov. Zool. iii, p. 539 (1896), while a reference to Horsfield's
original description and Plate (Zool. Res. Java (1824) of
P. montantis show these characters as strongly marked. Hors-

field's specimens came from Merbabu in Central and Prahu in
West Central Java, while my own material, consisting of over
twenty skins, is from the Gedeh in Western Java. Under these
circumstances I consider that the eastern form is perfectly
entitled to subspecific recognition, though in a considerable

discernible in the
Stachyris okientalis, sp. nov.
Separable at a glance from St. thoracica (Temm.) from
Western Java, (eight specimens examined), in having the
whole head and hind neck slaty black, clearly differentiated
from the mantle. Rest of the upper surface of a more
ochraceous rufescent, less chestnut tinge. Beneath, the white
pectoral collar forms a regular gorget and is not encroached
upon in the middle of the throat by the black of the chin and
neck, as in the western form. White gorget bordered beneath
by a black band broadest on the sides of the breast, this band
being entirely absent in St. thoracica.

Type:—Adult male from Sodong Jerok. Idjen Massif.
3,900 feet, near Banjoewangi, East Java, on March 28th, 1916.
Thirteen specimens examined.
Stachvkidopsis melanothorax intermedia, subsp. nov.
Intermediate between St. in. melanothorax 1 (Temm.)
from Western Java and St. m. baliensis (Hartert) 2 from Java.
Differs from the former in having the middle of the breast
sandy buff, uniform with the flanks, not white, and from the
latter in having the chin and throat pure white, only very
faintly tinged with buff. Outer webs of the primaries, decidedly
richer brown than the back but not nearly so bright as
the wing coverts.
