IXULUS. S20 
Distribution. Himalayas, Sutle] to Bhutan. 
Nidification. Similar to that of the preceding bird but, whereas 
the Chestnut-headed Ixulus generally places its nest on or almost 
on the ground, this bird seems to prefer to build it amongst the 
moss growing on the branches and twigs. The eggs cannot be dis- 
tinguished from those of the last and 28 average 19°81 x 14°2 mm. 
Habits. Those of the genus. This Ixulus is found between 
4,000 and 8,000 feet and keeps almost entirely to the greenest and 
most humid forests though it frequents the more open parts of 
these.

Ieulus flavicollis baileyi Stuart Baker, Bull, B, O.C., xxxv, p. 17 
(1914) (Mishmi Hills). 
Vernacular names. None recorded. 
Description. General plumage paler than in J. f. favicollis and 
the white shaft-lines extending over the whole of the upper 
parts: the ear-coverts have none of the bronze tint showing in 
that bird. 
Colours of soft parts. “ Iris red-brown; bill horny; tarsus dull 
yellow ” (Stevens). 
Measurements as in the preceding bird. 
Distribution. Mishmi Hills. 
Nidification and Habits. Not recorded. It is apparently this 
form which Stevens found in the foot-hills of N. Lakhimpur and 
the Abor Miri Hills. The birds from the N. Chin Hills are, 
perhaps, also nearest this form.
