edged ’externally with green, the two outer tail feathers on each side with the 
inner webs white ; wing coverts tipped with pale yellow ; margin of the wing, 
under wing coverts, belly and under tail coverts the same bright yellow as 
the rump. Iris brown, bill dusky above, deep yellow beneath, legs horny, 
soles yellowish. Measurement taken before skinning. Length nearly 4 in.,

°Mr. Blyth, Ibis, 1867, p. 26, says this bird is decidedly a Beguloides. 
So far as the hill is concerned, it appears to me that it might be classed in 
either of the two genera, between which in part there is no clear distmction ; 
the plumage is rather that of an Abrornis. 
Troglodytida. 
333 Troglodytes nipalensis, Hodgs. — The Nipal wren is common at 
high elevations. On the Chola range I especially noticed it above the range 
of forest, hunting over the loose moss-covered stones, which frequently form 
so large a portion of the hill sides, constantly entering the crevices between 
the blocks, and emerging again at a considerable distance. In the Lachen 
and Lachiing valleys, it was common in pine forests, at elevations above 
10,000 feet. I usually saw the birds in small families, 3 or 4 together, 
hunting on the ground and low hughes, and with the same predilec- 
tion for exploring hollows under stones. One of two specimens, fr om c ose 
to the Chola pass, is an old bird and measures, wing 2 in., tail T25, 
tarsus 0'75, bill from forehead 0 44, from gape 0'53. The other, from 
Yeomatong, is of decidedly more rufous tint, the bill is shorter an J e ow 
beneath ; this is probably a young bird. Its measurements ta en e ore 
skinning were : Length 41, wing 2, tail 1*2, tarsus 0-8, foot l’3o, bill from 
forehead 0 4 inch. 
329 P.nokpvga sqttamata, Gould.— This ranges up to about 8 ,000 feet 
in Northern Sikkim. All the specimens I saw belonged to the form called 
Tesia rufiventer by Hodgson which I am disposed to believe distinct from 
P. squnmata = albiventer, Hodgs., but I have not sufficient specimens for 
comparison. . 
327 Sesta CASTAXEO-COROXATA, (Burton) .-Not uncommon m Northern 
Sikkim at 7,000 to 10,000 feet. I saw several, but have only a single specimen. 
This bird is quite wren-like in habits, but keeps much less to the ground 
than Troglodytes Nipalemis. It is constantly on the move m low brushwood 
and grass, keeping up meantime a sharp monotonous single note repeated at 
regular intervals. 
527 Horeites brttoteierons, Hodgs.— Mr. Blyth long since, J. A. S. B., 
XIY 1845, p. 585, pointed out the similarity of this bird to Tesia ; except the 
much longer and slightly more rounded tail of Iloreites, there is but little
