This species is very closely allied to the preceding, and differs 

 from it only in having the general colour of the upper parts pale 

 brown instead of pale grey, and in having the white of the breast 

 and flanks suii'used with butt". There is no difference in the wing 

 formula ; bastard primary 0'85 to 0*7 inch. Length of wing 5"4 to 

 4'S5 inches, tail 2-9 to '2-bb, culnien 1*1 to 0*92, tarsus 1*5 to 1-35. 



Nothing appears to be known of the difference in the colour of 

 the plumage attributable to sex, age, or season. 



The Abyssinian Ground-Thrush is confined to the highlands of 

 Abyssinia, where it is a resident.
