. Tennaserim, Burmah, Siam, and Camboga ; Formosa, Hainan 

 (Hume and Sharpe). Occurs throughout Tennaserim, but Hume and Davison 

 say it is nowhere common. The species is excessively shy, seldom allowing 

 of even a moderately near approach. Feeds entirely on insects and small 

 reptiles.

The following is Sharpe's description of the adult plumage of this species : 

 The adult plumage appears to be gained by a gradual mersion of the 

 rufous stripes on the breast. Above light bluish grey, some of the feathers 

 margined with darker grey ; sides of face and neck grey like the head but a 

 little more dingy ; under surface of the body pale buffy vinous, the throat, 

 flanks, and thighs, as well as the under wing and tail coverts white with a 

 slightly greyish shade on the sides of the breast; quills black, externally 

 shaded with ashy grey ; under surface white at base of inner web, but having no 

 distinct bars above or below; tail dull bluish grey above, ashy white beneath, 

 with four or five indistinct cross bands of dark brown, a little plainer under- 

 neath, but these not strictly continuous. Cere yellow ; gape and orbits yellowish ; 

 bill black, lead colour at base; feet and irides yellow. Total length I r8 

 inches; culmen 075 ; wing 7-9 ; tail 5-4 ; tarsus rg. 



Young. Above brown, with rufous edgings to the feathers, a little broader 

 on the upper tail coverts ; the sides of the neck washed with rufous, the 

 nape mottled with white ; crown blackish ; an ill-defined eyebrow and fore 

 part of the cheeks white, narrowly lined with blackish brown. Ear coverts 

 brown, slightly washed with dull rufous ; throat buffy white with a moustachial 

 line on each side and a median streak of brown ; rest of under surface buffy 

 white, the chest broadly streaked and the breast and flanks barred with pale 

 rufous. Under tail coverts white ; under wing coverts clear buff, the lowest, 

 spotted with blackish. Quills dark brown, slightly tipped with whitish 

 very indistinctly barred above with darker brown ; underneath buffy white at 

 the base of the inner web, indistinctly barred with dark brown, visible only 

 on the inner webs ; tail ashy brown, whitish at tip, crossed with five bars of
