gined, especially near the base, and washed with olive. Under 
wing-coverts, hanks, and sides of belly rich rufous, more or less 
tinged with olive. The central quills of the wing on the under 
side pinkish ochre. Breast and centre of belly white, the former 
being largely spotted with black. These spots in some speci¬ 
mens are very scanty, in others rufous or rufescent, and in others 
consist of mere streaks. In most specimens the belly is spotted 
with large rufous spots; and in many the rufous on the flanks 
is largely encroached upon by the white of the belly. The tibiae 
and vent in all are of the colour of the back. 
The young bird is rather browner, but in other respects similar 
to the adult. 
I have specimens of this bird from Taiwanfoo, Apes' Hill, 
Tamsuy, Kelung, and Sawo, and they are all of identical form 
and colouring.

This species replaces in the central mountain forests the pre¬ 
ceding species of the lower country. It rarely, if ever, descends 
to the ranges below an altitude of 2000 feet, and certainly never 
leaves the gloom of the virgin forest for the partially wooded 
level of the plains. It enters upon its nidificatory duties much 
earlier than its congener, for in April I procured a couple of 
full-fledged young birds. I have never taken its nest, but had 
the good fortune to procure an egg which a female dropped as 
it fell wounded to the ground. This egg is white, and quite in 
character with those I possess of the other species, but larger, 
measuring 1*2 in. by *81. From its inaccessible haunts, I have 
not had many opportunities of watching the habits of this bird; 
but, as far as I can gather, they a good deal resemble those of 
its ally. Its notes are, however, harsher and less musical. Both 
the species are entirely insectivorous, having no partiality, so far 
as I could ascertain, for fruit or berries.
