THE GAME BIRDS OF INDIA, BURMA AND CEYLON. 9 
from above either eye to the upper neck where they meet ; lower neck 
or extreme upper back chestnut ferruginous with black spots ; back, 
rump, upper tail-coverts and tail olive with narrow black edges, and 
all but the back with bold black central spots ; scapulars and wing- 
coverts like the back but with still finer black bars ; wing quills brown, 
outer secondaries with mottled rufous and brown outer webs ; inner 
secondaries and greater coverts with chestnut edges, faint grey patches, 
and bold, black terminal spots. 
Below chin and throat pale olive chestnut, followed by white and 
black rings ; a small white moustachial streak, sides of head a darker 
chestnut, forming a collar with the chestnut on the neck and spotted 
with black in the same way ; upper breast deep rich chestnut ; from 
lower breast to vent grey, the flanks marked with chestnut in varying 
degree, and also more or less spotted with white ; the centre of the 
abdomen is often paler, and sometimes ashy in tint. Under tail- 
coverts olive, with white spots and rufous tips and markings ; the thigh 
coverts and extreme posterior flanks are often olive with black centres 
and rufous markings. 
Colours of Soft Parts ——Bill black ; irides red-brown. 
Measurements.—Total length about 275 mm. ; tail about 56-58 mm. ; 
wing from 133 to 145 mm., the average of 7 being 137 mm. ; tarsus 
43 to 45 mm. ; bill at front 19 to 20 mm. 
The female only differs in being a little smaller, but the material 
available does not suffice to give details. 
Distribution—The hills North of the Brahmapootra from Sikkim 
and Bhutan to the East of Assam. Bailey obtained a specimen on the 
upper Dibong Valley and Needham gave me some specimens from the 
hills North of Sadiya. 
Nidification—Nothing recorded, but my collectors sent me a skin 
of a female together with 4 eggs and notes to the following effect. 
The eggs were laid on the ground under shelter of a rock, but with 
practically no nest beyond a grass pad, in evergreen forest interspersed 
with Rhododendron and Oak, the ground much split up into ravines 
and cliffs, very rugged and very wet and humid in spite of the elevation, 
which was about 8,000 feet in the Chambi Valley. 
The eggs differ in no way from those of other species of Arboricola 
and measure about 43 by 34 mm. They are probably quite abnor- 
mally big eggs. 
They were taken on the 3rd June. 
Habits—The Red-breasted Hill Partridge is found principally be- 
tween 3,000 and 6,000 feet, descending a good deal lower in the Cold 
Weather, though it never seems to come actually into the Plains. In 
the summer it must often ascend much higher than 6,000 feet, for the 
nest taken for me in the Chambi Valley could not have been lower than 
8,000 feet, and may have been a good deal higher. In some nests 
taken by Mr. H. Stevens at altitudes a good deal over 6,000 feet, I
