IXULUS. 323 



Distribution. Himalayas, Sutlej 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*8 L 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 IXTTLUS. 



Ixulus flavicollis baileyi Stuart Baker, Bull. B. O. C., xxxv, p. 17 

 (1914) (Mishmi Hills). 



Vernacular names. None recorded. 



Description. General plumage paler than in /. f. Jlavicollis and 

 the white shaft-lines extending over the whole of the upper 

 parts: the ear-coverts have none of the bron/.e 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.

 THE CHEST^UT-NAPED IXULUS. 



Lvidits Jlavicollis harterti Harington, Bull. B. 0. C., xxxiii, p. 62 

 (1913) (Sinlum, Bhamo Hills). 



Vernacular names. Chee-chaw (Kachin). 



Description. Similar to /. /. Jlavicollis but differs in having the 

 crest a darker and richer brown : the collar a deeper and brighter 

 chestnut and the back a darker olive-brown. 



Colours of soft parts and Measurements as in /. f. Jlavicollis. 



Distribution. The Bhamo (Kachin) Hills and Trans-Salween 

 Shan States, Burma. Birds from S. Assam, Maaipur and S. Chin 

 Hills are also of this form though not so dark as more Eastern

 throughout S. Assam and also in the Bhamo Hills. Neither nest 

 nor eggs can be distinguished from those of the Himalayan forms. 

 Forty-eight eggs average 19-3x14-2 mm.
