tail coloured as in the male ; chin, throat, breast, and flanks huffish 

 white mottled with brown ; axillaries, under wing-coverts, and under 

 tail-coverts chestnut ; centre of belly pale chestnut. After the 

 autumn moult the blue-grey feathers of the upper and under parts of 

 the male are obscurely edged with brown, and the chestnut feathers 

 of the breast have pale edges. The upper parts of the female are a 

 darker brown, and the ground-colour of the underparts more chest- 

 nut. Birds of the year do not apparently differ much from adults. 

 Young in first plumage resemble the female on the underparts, and 

 have pale tips to the feathers of the upper parts. 



The Long-legged Eock-Thrush appears to be confined to South 

 Africa, ha^"ing been obtained at Cape Town and Kingwilliams- 

 town. It is not known to be a migratory bird.

In the adult male in hreediyig-jilumage the colour is similar to that 

 of M. explorator, but with the forehead and crown bluish white, 

 shading into pale slate-grey on the nape: tarsus much shorter. 

 Length of wing 4-2 to 3-95 inches, tail 2-61 to 2-56, culmen 1-0 to 

 0-9, tarsus 1-1 to 1-01. 



The aduU female in hreeding-jjlumage differs from that of M. ex- 

 plorator in having the upper parts sandy brown rather than sooty 

 brown ; the chin, throat, cheeks, and ear-coverts have each feather 

 nearly white with a brown margin. After the autumn moult males 

 resemble the breeding-plumage of males of 31. explorator, and are 

 scarcely distinguishable except by the shorter tarsus. Birds of the 

 year and young in frst plumage appear to be unknown. 



The Short-legged Eock-Thrush is found in Damaraland, Griqua- 

 land, and the Transvaal, where it is supposed to be resident.
