The followiiig is the synonymy of the intermediate forms, in which 

 the predominant strain is apparently derived from the preceding :— 



Saxicola leucomelaena-monticola.

Saxicola tephrouota, Gurney, Ibis, 1877, p. 343 (female). 



This is an intermediate form between S. monticola and S. leuco- 

 melcena. In typical examples the adult nude differs from either of 

 them in having the forehead, crown, and nape grey. It is also slio-htly 

 larger than either of its near aUies. Length of wing 4-55 to'4-35 

 inches, tail 3-1 to 2-75, culmen 0-U to 0-8, tarsus 1-35 to 1-2. 



The female is scarcely distinguishable from that of >S'. leucomalcena, 

 but 18 somewhat darker in colour and larger in size. The seasonal 

 changes are unimportant. Males between the second and th ird moidts 

 have the belly white as in the allied forms. Young in first plumage 

 appear to be unknown. Birds of the year supposed to belong to this 

 form arc brown, except the rump, upper and under tail- coverts, and 

 tail, which are coloured as in the adult. 



So far as is known, the geographical range of this form extends 

 from Great Xamaqua Land, through Colesberg, Blocmfontein to 

 Potchefstroom in the Southern Transvaal. It is supposed to be a 

 resident.
