 Saxicola saltatrix Shelley, p. 72. 



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 

 tlic alluvial districts, and it is, in fact, the only Wheatear 

 Avhich is found on cultivated ground throughout the year. 

 It moults in autumn. The sexes are indistinguishable, both 

 as regards size and colour. 



11. Saxicola occidentalis melanoleuca Guldenst. 

 Muscicupumelanoleuca Giildenstadt, Nov. Comp. Petr. xix.

? Saxicola eurymelcena S?ielley, p. 73. 



This form of the Black-throated Wheatear, which Las 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. Kat. i. p. 331 (1766). 



Saxicola aurita Temm. Man. d'Orn. vol. i. p. 241 (1820). 



Saxicola amphileuca Shelley, p. 72. 



Saxicola stapazina Salvador!, Ibis, 1904, p. 75. 



The " Eastern" form of the Black-cared 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.
