to Kcuch, above which it is less numerous. I fully agree with 

 Mr. S. Allen (Ibis, 1864, p. 237), that the fact of its being 

 resident throughout the winter, while H. rustica only arrives in 

 the spring, is a strong argument in favour of their being speci- 

 fically distinct ; besides which, the colour of the belly is so dif- 

 ferent in the two birds (that of H. cahirica being deep chestnut) 

 that I really cannot entertain the smallest doubt that the sub- 

 ject of the present note is a good species. 



43. HiRUXDo RUSTICA, L. Common Swallow. 



Began to appear about March 25th, and was common at Cairo 

 and Daraietta in April. 



44. CoTYLE RUPESTRis (ScopoH). Crag-Martiu. 

 Abundant in all rocky parts of Egypt. I saw several nests 



and procured some eggs in March ; both nest and eggs much 

 resemble those of Hirundo rustica. This species is resident 

 throughout the winter. 



45. CoTYLE RiPARiA (L.). Saud-Martiu. 



Large flocks of this species arrived in Upper Egypt early in 

 March, and immediately set to work to make holes in the sandy 

 banks of the Nile. I never saw Hirundo rufula in Egypt, but 

 I found it pretty common near Smyrna in April. 



46. MuscTCAPA coLLARis, Bcchsteiu. Collared Fly-catchei*. 

 Common at Damietta in April, when it had probably just 



arrived. 



47. Lanius dealbatus, De Filippi (Rev. Zool. 1853, p. 289). 

 Bleached Shrike. 



Procured in Upper Egypt in the winter, where, however, it is 

 not common. I never heard of its occurrence in the Delta. It 

 hardly differs from L. excubitor, but has the grey of the upper 

 parts rather paler in tint, and the white of the under jDarts purer. 

 It is a remarkable fact in the distribution of these Shrikes, that 

 in the north and centre of Europe there is a light-coloured 

 species [L. excubitor), in the south of Europe and North Africa 

 a dark-coloured species [L. meridionalis) , while the present 

 form is found in the Sahara, and Upper Egypt, to the south of 

 the regions inhabited by L. meridionalis.
