longest, the second and eighth equal in length, and about four lines shorter, 
the first about half the length of the longest ones, narrow, particularly towards 
the point. Tail moderately rounded : tarsi slender, faintly scutellated an- 
teriorly, entire posteriorly ; toes of moderate strength, the middle one con-

The colours of the female are the same as those of the male, only not quite 
so clear. The young bird (fig. b*) is highly variegated : the feathers of the 
head, neck, back, and rump are dull cream-yellow, tipped with dark brown ; 
those of the under parts, pale cream-yellow, tipped with reddish brown. 
The habits and configuration of this species, as has already been observed, agrees with those 
of j E, pectoralis ; like it, the present inhabits arid districts thinly covered with dwarf trees, 
among the branches of which it seeks its food. Its movements, while flitting from branch to 
branch, are rapid, and when resting or hunting for insects it is constantly watchful, always 
ready to take alarm and to retreat when its haunt has once been discovered. On such occa- 
sions, however, it rarely flies far before it alights, and if not under the influence of fear, it 
seldom passes the tree nearest to that it has abandoned. In its disposition to view every object 
with distrust, and to watch carefully whatever attracts its attention, it resembles in a marked 
manner the Saxicolce. 
* The specimen figured had acquired much of the plumage of an adult bird, hence the colours of youth 
are but imperfectly represented.
