 the upper mandible and an indistinct eye-stripe are slate-grey ; the 

 remainder of the forehead and crown sooty brown, each feather with 

 a dark shaft-line ; nape, back, scapulars, and wings sooty brown ; 

 rump, upper tail-coverts, and tail chestnut, the basal three fourths 

 of the two centre tail-feathers and a narrow terminal margin of the 

 remainder brown. Chin, throat, and breast slate-grey ; the rest 

 of the nnderparts, including the axiUaries and under wing-coverts,

The female differs from the male in having the forehead, eye- 

 stripe, chin, throat, and breast sooty brown like the back. Birds of 

 the year and youny injir.itplumarie appear to be unknown. 



This species is a connecting link between the genera Monticola 

 and Saxicola, and is also very closely related to Thamnohia. 



The Abyssinian Rock-Thrush appears to be confined to the high- 

 lands of northern Abyssinia, where it is said to be a resident.

The genus Sialia consists of a small group of birds, apparently 

 nearly allied to the Redstarts. The bill is short, slender, and black, 

 and the rictal bristles nearly obsolete. The legs are black, and the 

 tarsus unscutcllatcd. The tail consists of twelve feathers, and is 

 long and slightly forked. The -^-ings are very long and pointed ; the 

 bastard primarj- is very small, and the second primary as long, or 

 nearly so, as the third. The prevailing colours arc blue, occasionally 

 mixed with chestnut.
