one TIMALIIDA. 
Measurements. Total length about 130mm.; wing 64 to 68mm. ; 
tail about 50 to 52 mm.,; tarsus about 20 mm.; culmen about 
10 mm, 
Distribution. Garhwal, Nepal, Sikkim and Bhutan to the 
extreme east of Assam, Manipur and the Chittagong Hiil tracts. 
Nidification. This Ixulus breeds between 4,000 and 7,000 feet 
in May and June, the nest varying very greatly in character, 
shape and position. Normally it is domed and placed either on 
or close to the ground, but sometimes it is semi-domed or merely 
deep cup-shaped and may be built in a branch of a tree or shrub, 
in amongst the lichen and moss hanging from a trunk or bough, 
or it may even be placed in a niche in a rock. The material used 
is always chiefly moss but this may be mixed to a lesser or 
greater extent with roots and chips of leaves or bracken, the lining 
being of roots alone. The eggs number three or four and are in 
every respect just like those of our English Swallow but the 
markings are more numerous as well as bolder and_ larger. 
Sixty eggs average 19°3 x 14-2 mm. and the extremes are 21°3 x 
14:0 mm., 20-1 x 15:0 mm. and 17°3 x 14:0 mm. 
Habits. These are just like those of Yuhina. They fly well, 
and their note is a rather sweet, soft chatter. They are very 
arboreal and may sometimes be seen on the highest trees. They 
keep almost exclusively to evergreen forest.
