 Arabs informed him that for one Swallow they 

 have in winter they have twenty in summer, and 

 that they usually retire about the end of Nov- 

 ember, returning in February. In November, 

 also, they have been observed to be common at 

 Alexandria and Cairo (E. C. Taylor, " Ibis,"

 when leaving Aden, Mr. Swinhoe remarked that 

 a few Swallows followed the ship, apparently

 March 25, and is common at Cairo and Damietta 

 in April. Ruppell, in his " Systematische
