parties and keep much to the fringe of forests, the sides of roads 
and streams and open glades, and when perched on the topmost 
twig of some tall bush they do look extremely Shrike-like but 
directly they move the resemblance disappears. They are sedate 
and rather slow in their actions as they hop about or clamber 
through the bushes and scrub and their flight is jerky, dipping and 
rather feeble. They are not shy birds and keep up a continuous 
grating ‘‘ chirr”’ when being watched but they also have some loud 
musical call-notes. They feed both on insects and berries and seeds.

(Tenasserim, 3,500-4,500 ft.) ; Blanf. & Oates, i, p. 225. 
Wernacular names. None recorded. 
Description.— Male. Differs from the last in having the inner 
secondaries golden yellow on the outer webs and edged with black 
on the inner webs and tipped with black. The lower plumage is 
also more grey. 
Colours of soft parts. ‘‘ Legs and feet fleshy white ; claws pale 
brown to black ; lower mandible and basal edges of upper mandible 
along commissure pale blue, rest of the bill black; iris varied con- 
siderably, slaty grey, pale greenish grey and deep brown ” (Hume 
& Davison), 
Measurements a little smaller than the last; wing 75 to 81 mm. 
The female differs in having the inner secondaries green, tipped 
with chestnut and the back grey. 
Distribution. The Kachin Hills, East of Bhamo, the hills of 
Central Hast Burma, Muleyit and probably other ranges in Ten- 
asserim and the North of the Malay Peninsula. 
Nidification. Unknown. 
Habits. On Muleyit, Davison found this bird in pairs or singly, 
frequenting the tops of the highest trees, hunting the smaller 
branches and foliage for insects. Its note he syllabifizes as 
“too weech.” He also says that if one of a pair is shot, the other 
at once commences calling and hunting for its companion. This 
trait is also seen in the last bird. 
Probably all the forms of e@ralatus should be treated as geo- 
graphical races of erythropterus, but in the series available for 
examination I have seen no intermediate forms.
