most parts, high altitudes. These birds are chiefly migrants from 
North Asia, in the cold weather. 
(365) PLANESTICUS ATROGULARIS, Black-throated Thrush, con- 
vregates in winter, here, in fairly big numbers. They keep much 
to taller trees, and feed on berries, occasionally descend to the 
ground for insects. Atrogularis is 104 inches in length; plumage 
of the male is pale ashy-brown; wings and tail darker; feck, has 
a blackish pectoral gorget ; bill and orbits yellow ; lower tail-coverts, 
barred with brown lines; breast and under parts whitish-brown, with 
dark streaks. 
GENUS OREOCINLA 
Comprise, thrushes with strong, longish bills; wings long; toes 
long; birds of soft silky, spotted plumage. 
(370) OREOCINCLA MOLLISSIMA, Plain-backed Mountain Thrush. 
(371) ORROCINCLA DAUMA, Small-billed Mountain Thrush. The 
last two birds found in the district of this family, are similar to 
each other, in habits and general appearance; so that it will be 
more convenient to examine them together. Both species are gre- 
garious, they are seen much together in companies of five or six at 
a time; when approached, they rise off the ground, where they 
have been feeding, usually in hollows on the hill side; in places 
where trees are plentiful. It is among the dead and decaying leaves, | 
ferns and mosses. that they usually feed, scratching the ground like 
game-birds, for insects and earthworms. It is curious that a dog 
(hunting) will stand, to both these birds when flushed, as though 
they were game, which it won't do to any of the other thrushes. 
Mollissima is the smaller of the two, being 95 inches, whilst dswmna 
is 105 inches in length. Both birds are good specimens of moun- 
tain thrushes, both in colour and habits. They ascend a good alti- 
tude in spring. I found Mollissima nest building beyond Jongri up 
to about 13,000 feet elevation. Dauwma is usually distinguished 
when in company with the former species by its more conspicuously 
spotted back and body, also by its much smaller bill. This bird is 
prettily marked with black and white spots. J/ollissima has rich 
olive brown plumage with an orange tinge; under parts white and 
tawny or dull yellow.
