1921 .] the Near East and Tropical East Africa . 
At first sight, many of the specimens I collected in eastern 
Africa looked very like the western rayi , for they had 
greenish heads. But campestris has a yellowish-green 
back and more yellow on the head and sides of the neck 
than rayi , the latter having a slight brown tinge on the 
back, which is never the purer yellow-green colour of 
campestris. Quite 30 per cent, of my eastern African 
campestris had green heads. 
Motacilla f. pygmaea Brehtn. 
A partial resident in the Egyptian Delta and the Fayoum, 
large numbers disappearing in mid-winter. I am not, how¬ 
ever, aware of its occurrence outside Egypt, Butlers bird 
(Ibis, 1909, p. 392) being apparently wrongly identified (see 
also Sclater & Praed, Ibis, 1918, p. 613). 
Motacilla f. leucocephala (Przew.). 
Yellow Wagtails with white heads have been obtained in 
Egypt and eastern Africa, and are supposed to be aber¬ 
rations. Is Przewalski’s leucocephala also an aberration ? 
It was first described in 1887 from birds obtained in the 
southern Altai ; it was again reported by Zarudny at Merv 
and on the Oxus in Turkestan. Whistler shot a male at 
Jhelum in India on 2. v., Zarudny again collected three in the 
Orenburg District (Grrote, J. f. 0. 1919, p. 372), and Suschkin 
states they breed regularly (sic) in the Tschalkar District of 
the Khirgiz Steppes and occasionally in the Steppe Province. 
Finally, Suschkin (Messag. Ornith. 19.15) found a breeding 
colony at Achit Nor in north-western Mongolia, where he 
describes them as common in the swampy meadows, having- 
obtained 18 birds and eggs. It would therefore appear that 
this race is not an aberration, and that its breeding ranee is 
a narrow strip of country running just south of the range of 
beema , from north-western Mongolia to the Khirgiz Steppes, 
but it is everywhere rare and local. 
Motacilla f. feldegg Michahelles. 
Uncommon on autumn passage during September in 
Palestine and not uncommon in Egypt, where some years it
