dirty white on the inner web and buff on the outer web ; 

 secondaries widely margined with buff, as also the primary, 

 median, and lesser wing-coverts ; under wing-coverts and 

 axillaries white; scapulars white; rectrices dark brown 

 margined on the outer web with buff; cheeks, lores, and 

 ear-coverts blackish. A conspicuous white stripe extending 

 from the bill over and beyond the eye ; eyelids white ; chin 

 pure white — the white extending beneath the cheeks and 

 forming a half-collar ; chest, breast, belly, and flanks nearly 

 uniform vinaceous buff, rather darker on the chest ; under 

 tail-coverts whitish. 



Iris dark brown ; bill and feet black. 



Culmen (exposed) 11 mm. ; wing 65 ; tail 47; tarsus 23. 

 Adult female . Differs from the male in wanting the black 

 cheeks, lores, and ear-coverts, which are light brown, and in 

 having the entire underparts much paler vinaceous buff. 

 Culmen (exposed) 11 mm.; wing GO; tail 48; tarsus 23. 

 Immature birds are, if anything, darker on the upperparts 

 than the adults and can be distinguished at once by the 

 white tips to the feathers of the crown, nape, and hind neck, 

 which give to the bird a speckled appearance. The white 

 half-collar and scapulars are quite distinguishable in the 

 young bird. The chin and throat are less pure white, and 

 the breast is pale buff with minute brown tips to each 

 feather. The flanks are very pale buff, almost white. 



Comparison with Saxicola d. dacotice. — In the worn 

 plumage at the commencement of the autumn moult an 

 adult male, killed on the 12Lh of June in Allegranza, differs 

 from an adult male of S. d. dacotia, killed on the 17th 

 of June in Fuerteventura, in having the crown of a lighter 

 and more reddish brown, not showing the marked con- 

 trast with the rest of the upperparts. The underparts from 

 the chest downwards are nearly uniform vinaceous-buft', 

 rather more deeply coloured on the upper part of the chest, 

 while in S. d. dacotioe the chest patch is of a rather more 

 rusty tint and the belly and flanks are usually much paler 

 and inclined to whitish.
