THE GAME BIRDS OF INDIA, BURMA AND CEYLON. 21 
second black line at the edge of the base of the upper mandible ; back 
of the neck grey, the feathers boldy edged with velvety black and with 
a few longitudinal and cross bars of chestnut ; upper back reddish- 
brown with black blotches, the feathers margined rufous on either web; 
the feathers on either side of the back with pale buff central streaks ; 
lower back and rump vermiculated buff and pale grey with a few 
scattered black specks and spots; upper tail-coverts and tail same, but 
more rufous, and the mottlings forming ill-defined bars on the latter ; 
scapulars mostly buff with rufous brown edges and grey mottling ; 
innermost secondaries chestnut-brown with deep, red margins, black 
spots on the inner webs, buff tips and much mottled with buff and grey; 
wing-coverts bufi, mottled with grey and brown ; primaries brown, 
mottled with chestnut-bufi on the outer webs ; outer secondaries buff 
with mottled brown bars. 
Chin and throat like the sides of the head but paler ; neck and upper 
breast grey, changing into rufous-buff on the lower breast and flanks, 
and again to almost pure white on the abdomen and vent ; under tail- 
coverts pale rufous. 
Colours of Soft Parts—* Iris burnt umber ; bill black, legs lemon- 
yellow ” (Herbert). 
Bill black, legs flesh colour, claws horny ” (Hopwood). 
Measurements.—Length about 220 mm., tail about 80 to 90 mm., 
Wing from 189 to 211 mm., average 10 birds, 197°5 mm. ; tarsus 
55 to 63 mm. ; bill at front 28 to 33 mm. 
Adult Female.—-Differs from the male in having nearly all the grey 
of the neck and breast replaced by rufous-chestnut ; the rump, upper 
tail-coverts and tail are generally more rusty and less grey, and the 
rusty of the lower part is deeper and more extensive. 
Colours of Soft Parts.—-Apparcutly as in male. 
Measurements. —Wing 180 to 202 mm., average 8 birds, 190 mm. ; 
tarsus 54 to 58 mm., bill 24 (possibly juv.) to 33 mm. 
Young Male is like the female, but retains traces of barring on the 
feathers of the breast and flanks, and probably this barring is still 
more extensive in the quite young bird. 
In this Partridge the depth and extent of the rufous on the head and 
upper parts varies considerably in both sexes ; in the female practi- 
cally the whole of the underparts are sometimes rufous, but occasion- 
ally in this sex and more often in the male the abdomen is extensively 
white. 
Distribution.—8. W. Siam and Tennasserim throughout the Malay 
Peninsula to Sumatra and West Borneo ; but replaced in some of the 
mountains of Borneo by another race, dulitensis of Ogilvie-Grant. I 
cannot discover any difference between birds from Sumatra and those 
from the most Northern parts of its range. 
There are two birds in the British Museum collection labelled 
‘“‘ China, ” possibly meaning Cochin China.
