limited below by a narrow black band which extends from 
the base of the upper segment of the beak backwards under 
the eye to the ears ; above this a white stripe extends back- 
wards behind the eye; rest of head, and back of neck, 
mouse-brown ; back, scapulars, and wings, brown; there is 
a narrow white alar bar; primaries, dark brown, the shafts 
of all and the outer webs of the shorter ones marked with

is a black ring, broadest in front at the upper breast ; 
lower breast, abdomen, and under tail-coverts, white ; upper 
tail-coverts, greyish-brown; outer pair of tail- feathers, 
white ; central pair almost completely brown, tipped with 
white, this colour increasing in the lateral series, the
