Siam *. 
Nidification not recorded.

dense forest and the more open bamboo-, grass- and scrub-jungles. 
(280) Stachyridopsis rufifrons ambigua. 
Harineton’s RED-FRONTED BABBLER. 
Stachyrhidopsis rufifrons ambigua Harington, J. B. N. H.S., xxiii, 
p- 631 (1915) (Gunjong, N. Cachar), 
Vernacular names. Dao-pere-gajao (Cachari). 
Description. Differs from the last bird in having the white of 
the throat grading into the fulvous of the lower plumage. The 
black shaft-stripes on the crown and nape are very conspicuous and 
the upper plumage is less grey and more olive-green; the flanks 
and thighs are strongly washed with olive-brown. 
Colours of soft parts. Irides reddish brown; bill slaty-blue ; 
lees and feet pale yellowish brown, claws darker. 
Measurements. Total length 115 to 120 mm.; wing 48 to 
53 mm.; tail 46 to 48 min.; tarsus about 17 tol8 mm.; culmen 
9 to 10 mm. 
Distribution. Sikkim, Assam North and South of the Brahma- 
putra, Manipur. 
Nidification. The breeding season of Harington’s Red-fronted 
Babbler commences in the end of March in the plains to the end 
of June or even July in the hills. It breeds everywhere up to 
2,000 feet and occasionally higher than this and nests of both 
ruficeps and ambigua may be found in the same jungle. Nest 
and eggs are quite indistiguishable from those of the Red- 
headed Babbler and, as with that bird’s eggs, pure white ones may 
sometimes be taken of this bird. One hundred eggs average 16-1 x 
12-4 min. 
Habits. This species differs from the last in being a bird of much 
lower levels. It extends well into the plains and is more plentiful 
below 2,000 feet than over this height, though it wanders frequently 
as high as 3,000 feet or a little over. It is more a bird of com- 
paratively open bamboo- and scrub-jungle, grass-lands and thin 
deciduous forest than of the deep evergreen forests, though it will 
be. found in these also. It is a companionable, cheery little bird, 
collecting in quite big flocks and having much the same manners, 
voice and diet as the Golden-headed Babblers. 
* Specimens from S.W. Siam have been separated by me under the name 
S.r. obscura and this form may possibly be found in extreme 8.E. Tenasserim.
