The dark-grey headed forms, which a])proach nearer to S. mnnticola 

 than they do to 'S. lemvmehnm, are fortunate in having no synonymy. 

 They may be called 



Saxicola inonticola-leucomelsena. 



This form is very nearly allied to Saxicola montlcola, but differs 

 from it in the adult male having the forehead, crown, and nape dark 

 grey, with a broad ill-defined paler grey eye-stripe. It appears also 

 to be intermediate in size between the preceding and the following 

 forms. Length of wing 4-5 to •4-2 inches, tail 3-0 to 2-9, culmen O'SS 

 to 0-8, tarsns 1-34 to 1-21. 



The female is a darker grey even than that of S. monticola ; bnt the 

 upper and median wing-coverts arc white. The seasonal changes 

 are unimportant ; the annual moult takes place in January and 

 February. The male of the second year has the belly white, as in the 

 nearly allied species. " Toang in frst pluuiar/c appear to be unknown. 

 Birds of the year are entirely brown, with the exception of the rump, 

 upper and under tail-coverts, and tail, which are coloured as in the 

 adults. 



This form is only known from Potchefstroom, Colesberg, and Xatal. 

 It is supposed to be a resident. 



The synonymy of the black-headed form is as follows : —
