MoNTicoLA sAXATiLis (Linn.). 



Monticola saxatilis Slielley, p. 70. 



This Kock-Thrusli was first seen on IMarcli 21 st^ when 1 

 obtained a male; a day or two later several more appeared. 

 The first arrivals were adult males. One adult male in 

 perfect autumn plumage was obtained by Mr. Balboni on 

 September 20th, 1910. 



Monticola solitarius transcaspicus Hartert. 



? Monticola cyanas (Linn.), Shelley, p. 70. 



First seen on March 19th, after which date I met with and 

 obtained several specimens, all adult males, during my stay. 



All my specimens from the Wadi are referable to Hartert's 

 M. s. transcaspicus, which is paler than the typical form. 



Saxicola cenanthe (enanthe (Linn.). 



Saxicola cenanthe (Linn.), Shelley, p. 71. 



The Wheatear was just arriving from the south when I 

 reached the Wadi on J\Iarch 18th. After a day or two 

 immbcrs appeared and they were excessively numerous up 

 to the time of my departure. 



Saxicola cenanthe argentea Lonnberg. 



Saxicola cenanthe argentea Lonnberg, Arkiv for Zoologi, 

 V. No. 9, p. 22 (1909). 



Saxicola cenanthe leucorrhoa Nicoll, Ibis, 1909, p. 287. 



On March 21st, 1910, 1 shot an adult male which appears 

 to be of this form. 



It is probable that this form frequently occurs amongst 

 the numl)ers of Wheatears which pass through the Wadi 

 during the sjn'ing migration. I have not yet found *S'. ce. 

 rostrata in that locality, but it probably occurs there, as I 

 have three adult males from Giza. 



The three forms of Saxicola renanthe which occur in Egypt 

 may be distinguished as follows : — 



S. ce. cenanthe. — Adult male. Wing less than 100 mm. 

 S. ce. argentea. — Adult male. Wing 100 mm. or more ; 



bill same size as in S. (i\ cenanthe. 

 S. re. rostrata. — Adult male. Wing about 100 mm. ; 



bill long and slender, about 20 mm.
