In Armenia the passage of northern migrants occurs 

 from the middle of August to the middle or end of October. 

 Birds commence arriving in Egypt in early September 

 and passage continues till early October ; none winter in 

 the Egyptian Delta, but I saw a small flock at Siwa Oasis 

 on 26. i. 



Most birds have left Cyprus by the middle of October. 



Birds commence arriving in Abyssinia from early Sept- 

 ember, and large flocks were seen crossing the Red Sea 

 just north of Port Sudan on 2.x. A few winter in Abys- 

 sinia. Both adults and birds of the year arrive in Somaliland 

 towards the end of September. 



I have no records of the autumn arrival of Swallows in 

 the Sudan, though many appear to winter there.

 to 2.ii.,w]ien a continual passage north was noted from dav.n 

 to 10 A.M. each day. On 7.ii. and 21. ii. parties were noted 

 moving north in Rhodesia, and a few arrived in north-west 

 Arabia as early as IG.ii. 



In Cyprus, probably the most southerly breeding limit 

 of this Swallow in the Near East, they arrive abun-
