The Isabelline Wheatear seems to be resident in Egypt, 
for I have seen specimens shot in January, February, April, 
August, September, and December. This species frequents 
the cultivated lands more than the desert in the Giza 
Province. It is by far the commonest Wheatear found in 
the alluvial districts, and it is, in fact, the only Wheatear 
which is found on cultivated ground throughout the year. 
It moults in autumn. The sexes are indistinguishable, both 
as regards size and colour.

? Saxicola eurymelana Shelley, p. 73. 
This form of the Black-throated Wheatear, which has the 
black extending to the upper breast, is a regular spring and 
autumn visitor to Egypt. I have seen it during both migra¬ 
tions in the province of Giza, but at present the only 
examples that I have are individuals shot during the autumn 
migration. A splendid white-backed male frequented the 
Zoological Gardens for several days during the spring 
migration of 1907. 
12. Saxicola stapazina stapazina. 
Motacilla stapazina Linn. Syst. Nat. i. p. 331 (1766). 
Saxicola aurita Temm. Man. d'Orn. vol. i. p. 241 (1820). 
Saxicola amphileuca Shelley, p. 72. 
Saxicola stapazina Salvadori, Ibis, 1904, p. 75. 
The “ Eastern ” form of the Black-eared Chat seems to be 
a regular visitor in spring and autumn. I have examined 
the following specimens obtained in the Giza Province :— 
An adult male from Abbassia, April 10th, 1908 (Capt. 
J. B. Jenkinson) ; two adult males in full winter-plumage, 
obtained by myself at Giza, September 14th, 1908. 
During the spring migration of 1907 I saw an example of 
this form in the Zoological Gardens.
