General colour of the upper parts russet-brown, inclining to olive 

 on the back, slightly paler on the rump and upper tail-coverts, and 

 shading into rich russet-brown on the forehead ; lores and behind 

 the eye dark brown ; eye-stripe pale huffish white, indistinct, and 

 not extending far behind the eye ; wings and tail brown, the out- 

 side webs of the feathers edged with russet-brown. Chin, throat, 

 and centre of belly nearly white, shading into pale huffish brown on 

 the breast, flanks, and under tail-coverts ; thighs bro\vn ; axillaries 

 and under v/ing-coverts silky white ; inner margin of quiUs pale 

 brown. Bill rather stout ; upper mandible dark brown, under 

 mandible pale horn-colour, darker towards the tip ; rictal bristles 

 moderately developed. Wing slightly concaved, with the fourth and 

 fifth primaries nearly equal and longest ; second primary about equal 

 in length to the secondaries ; bastard primary slightly more than 

 half the length of the second. Tail shorter than the wing, the out- 

 side feathers 0'35 to 0-45 inch shorter than the longest. Legs, 

 feet, and claws pale brown. Length of wing 2-53 to 2-2 inches, 

 tail 2-35 to 2-0, culmeu 0-65 to 0-50, tarsus 1-0 to Q-O. 



The female appears to have rather less of the rich russet-brown 

 on the forehead. After the autianu moult the slight shade of olive 

 on the back disappears, and the russet-brown on the forehead is 

 much richer in colour, and extend more onto the crown. The 

 huffish brown of the breast, flanks, and under tail-coverts also 

 becomes darker. The plumage of birds of the year appears to be 

 unknown.
