ixL'Lus. 323
Distribution. Himalayas, Sutlej to Bhutan.
Nidification. Similar to that of the preceding bird but, whereas • the Cheshiut-heiuled Ixulus generally places its nest on or almost on the ground, this bird seems to prefer to build it amongst the uioss growing on the branches and twigs. The eggs cannot be dis- tinguished from those of the last and '28 average 19"8L Xl4'2 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.
(346) Ixulus flavicollis baileyi.
The MisHMi Ixulus.
- Ixuhm flavicoUis baileyi Stuart Baker, Bidl. B. 0. C, xxxv, p. 17 (1914) (Mishmi Hills).
Vernacular names. None recorded.
Description. General plumage paler than in I. f. flavicollis 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; t:irsus 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 jN". Chin Hills are, perhaps, also nearest this form.
