replaced by brown, and have dark l)ars across the ends of the smaller 

 featliers, and ochraceous sijots at the tips of the wing-coverts.

In the adnit male the general colour of the upper parts is dull 

 olive-brown, shading into russet-brown on the forehead, some- 

 what darker and browner on the inner webs of the quills and tail- 

 foathei-s ; lores and ear-coverts brown ; no trace of eye-stripe. 

 Chin and iipper throat white, with longitudinal dark-brown streaks, 

 which become almost confluent on the cheeks ; breast grevish 

 brown, shading into bright orange-chestnut on the flanks and belly; 

 under 1 ail-coverts brown, with white centres running out to the 

 tips ; axillaries and under wing-coverts bright huffish chestnut ; 

 inner margin of quills pale chestnut-brown. Bill dusky yellow 

 above and below. Wings with tlie third, fourth, fifth, and sixth 

 primaries nearly equal and longest, second primary between the 

 seventh and eighth, bastard primary 1-0 to 0-8 inch. Legs, feet, and 

 claws pale. Length of wing 5-05 to 4-45 inches, tail 3-9 to 3*4, 

 culnien 1-U to 0-9, tarsus 1-4 to 1-2. 



There appears to be no diff'erence in the plumage of the scvex, 

 nor does any change worthy of note take jilace by abrasion. Birds 

 of the year have the wing-coverts tipped with chestnut, and most 

 of the feathers of the upper and under parts with obscure lilack 

 terminal bars. Tcmwj in Jirst plunidi/e have the usual ochraceous 

 shafL-lines to the feathers of the upper parts, and black terminal 

 bars to tliose of the uiid('ri>arts. 



The Olive Thrush is found in the Transvaal, Xatal, and in the 

 Cape Colony, where it is a resident.
