Siixicola deserti, Temm. apud Blnnf. ^ Dresser, P. Z. S. 1874, 

 jj. 22-1 (/xirtim ). apud Dresser, B. Eur. pt. xxv. (1874, partim), 

 apud Blunf. East. Pers. ii. p. 148 (Id'iij, partim). 



The adult male in hreeding-pluniage differs from that of the 

 preceding species in being slightly larger, in having scarcely 

 any trace of buff on the breast and bell}-, which is nearly pure 

 white, and in having the basal half of the inner web of the primaries 

 and of the adjoining five secondaries white to the shaft, a character 

 which is as strongly developed in the young in first plumage as in 

 the adult. Length of wing 4-0 to 3-7 inches (females 3-9 to 3'6), 

 tail 2-7o to 2-35, culmen 0*74 to 0'6S, tarsus 1*1 to O-Do. 



The female scarcely differs in colour from that of the preceding 

 species, but is a much larger bird. After the autumn moult the 

 black feathers of the throat are tipped with buff. Males of the year 

 resemble females, except in having the basal half of the inner web 

 of the primaries and of the adjoining secondaries white to the shaft, 

 a character which is also as strongly marked in males in first j)lu mac/ e. 

 Youiu/ in first plumarje of both sexes are greyer in colour than 

 females, and have the feathers of the breast and back with obscure 

 pale centres and dark margins.

Saxicola melanoleuca and Saxicola stapazina. 



This Chat has two forms, which have been separated specifically 

 bj' Brehm, Blanford, and Dresser, in my opinion on insufficient 

 grounds. As they may, however, be regarded as imperfectly 

 segregated subsjjecies, I have kept their synonymy distinct. That 

 of the Eastern form is as follows : —
