it owing to its being in the midst of an impenetrable 

 swamp. 



That this form should occur in the Wadi Natron is not 

 surprising as it is common in the Delta and in the Fayoum. 

 I have obtained a specimen at Luxor. It is easily recognis- 

 able at a distance by its small size and dark coloration.

On March 24th, 1910, I shot a single adult male of this 

 form in the Wadi. 



M. f. nielanogrisea is most nearly allied to M. f. melano- 

 cephala, from which it differs in the following particulars : — 

 Crown dull black ; nape greyish black ; chin and upper 

 throat whitish ; a white line from the gape along the sides 

 of the head below the ear-coverts. The under parts are pale 

 sulphur-yellow. Measurements smaller than those oi M.f. 

 melanocepliala.

The Black-headed Wagtail was the most numerous of the 

 Yellow Wagtails during my visit. They passed in streams 

 daily, all going northwards, and some specimens were 

 obtained. Of all the "Yellow" Wagtails the present form 

 is perhaps the most well marked ; it is easily recognisable 

 at some distance. The call-notes of this and all allied forms 

 are similar.

During my visit in March a few Meadow-Pipits were seen 

 daily. In November 1911 this species was not uncommon.
