Ou August 15th, 1910, Mr. Balboni obtained an adult 

 male Red-backed Shrike, and three days later an adult 

 female ; both of these birds were just beginning to moult. 



Up to the present time I have no records of the occurrence 

 of the Red-backed Shrike in Egypt in spring, although it is 

 a regular visitoi', in large numbers, during the autumn 

 migration. 



MUSCICAPA GRISOLA. 



Muscicapa grisola Shelley, p. 118, 



Three Spotted Flycatchers were collected by Mr. Balboni, 

 one on April 28th, one on May 5th, and one on May 7th, 

 1910.

An adult male of the Half- collared Flycatcher was obtained 

 by Air. Balboni on April 13th, 1910, and forwarded to me. 



The occurrence of this subspecies in the Wadi Natron 

 is of exceptional interest, as during April 1910 this race 

 was frequently observed at Giza, Avhere the first Egyptian 

 example recorded was obtained in April, 1909. It is highly 

 probable that owing to its confusion with the Pied Fly- 

 catcher (M. a. atricapilla) this interesting form may have 

 been previously overlooked in Egypt. It only differs from 

 the Pied Flycatcher in having the sides of the neck white, 

 whereas in the typical form the sides of the neck are 

 black. 



The Half-collared Flycatcher is a subspecies of M. a. 

 atricapilla, and has the outer webs of the three outer 

 pairs of rectrices white, whereas in M. collaris the white 

 is restricted to the outer pair 07ily and is sometimes even 

 entirely absent.
