Machetes pugnax (Linn.).

The magnitude of the spring migration of Ruffs in Lower 

 Egypt must be seen to be believed. ]\[y visit to the Wadi 

 Natron in JNIarch 1910 coincided with the northward 

 movement of this species, and I must have seen many 

 thousands of Ruffs in a few days. On March 24th a very 

 strong migration of birds took place, and on the evening of 

 that day and throughout the following day the shores of one 

 of the Salt Lakes was literally black with Ruffs and Reeves — • 

 flock after flock, some numbering hundreds, were seen 

 arriving and settling on the already crowded shore. Nearly 

 all of them were still in winter plumage or only just beginning 

 to moult, though I saw one with a partial " ruff." During 

 my stay I saw several examples with a pure white neck and 

 no ruff, and one of these was shot and given to me by 

 Mr. Balboni. 



ToTANUS HYPOLEUCUS. 



Actit'is hi/poleucos Shelley, p. 259. 



Several Common Sandpipers were seen during my visit in 

 March, but no examples were obtained. 



ToTANUs ocHROPus (Linn,). 



Tetanus ochrop?(,s Shelley, p. 258. 



The Green Sandpiper was frequently met with in i\rarcli 

 1910, nearly always in the fresh-water or brackish pools, and 

 examples were obtained. In November 1911 I met with 

 fair numbers in similar situations. 



ToTANUS GL AREOLA (Liuu.). 



Tutanus glareola Shelley, p. 259 ; Loat, Ibis, 1905, 

 p. 459. 



The Wood Sandpiper was fairly numerous during March 

 1910. Most of those seen frequented the fresh-wacer springs 

 near the Salt Lakes. 



I have an adult female got by Mr. Balboni on April 18th, 

 1910, and an immature bird on August 25th, 1910.
