366 MARQUIS OF TWEEDDALE ON NEW INDIAN BIRDS. [Apr. 17, 
7. Descriptions of three New Species of Birds from the Indian 
Region. By Artuur, Marquis of TwrEpDALe. 
[Received April 14, 1877.] 
Two of the species about to be described were obtained by 
Mr. Ossian Limborg on or near the Miulé-it range of mountains in 
Tenasserim, a locality which had only been once previously visited 
by a naturalist, namely, the late Colonel Tickell. The third 
species formed part of a collection of birds made by Mr. Edmund 
Charles Buxton in the Lampong district of Sumatra. 
TRICHOSTOMA LEUCOPROCTUM, Ni. Sp. 
. Above olivaceous ruddy brown, more rusty at the tips of the 
upper tail-coverts, greyish on head, a tinge of pale rufous on a 
narrow frontal band, passing to the pale lores. Two centre tail- 
feathers umber-brown. The three outer tail-feathers edged pure 
white on the inner web, the extent of white edging increasing 
inwards, until the whole inner web of the antepenultimate feather 
is white, while the fourth is broadly edged white for nearly its 
whole length on the opposite or outer web. Shoulder of wing rusty 
olive, the primaries dull rusty brown. Blotch of white on the 
upper breast, which is dull pale olive-brown, fading into the pure 
white of the under tail-coverts. Wing rounded; first primary 4 
the length of the second, which is } inch less than the third, fifth 
the longest. Tarsus and feet moderately strong for the group. 
Length about 63 inches, wing 3:5, tail 3°0, tarsus 0°9, bill at 
front 0°63. 
Legs and feet grey ; ivides dark brown. 
Hab. Base of the Mulé-it range, Tenasserim. Obtained by Mr. 
Ossian Limborg. 
Curysococcyx LIMBORGT, Ni. Sp. 
Desc. Above fine rich purple with steel reflections ; wings and tail 
the same, somewhat darker; throat and breast same as the back. 
Two outer tail-feathers with a similar white tip, and four spots on 
the outer web of the last, with a short white streak on the inner 
web opposite each spot, the two together having a tadpole-like 
outline. Lower breast and vent white, the feathers broadly barred 
with green and purple, and overlapping, form a succession of regular 
bands; the bars on the under tail-coverts are broader and of a 
stronger purple tint. Under-surface of wing white at the inner 
base of the primaries and secondaries, forming a narrow white 
bar inside the wing; a pure broad white crescentic collar on the 
‘lower nape, commencing low down on the side of the neck. Bill 
yellow. Legs rich green. Irides red, and a bright crimson orbital 
skin. 
Length about 6 inches, wing 4:0, tail 3:1, tarsus 0°6. 
Hab. Base of Miulé-it range, Tenasserim.
