BIRDS OF EGYPT, 



T. auritm. Its egg is intermediate in size, and, from tlie one 

 specimen I broaglit home, appears to be of a less pure white 

 than those of the other two species. In the beginning of 

 April it so far surpassed in numbers its congener, T. sene- 

 galensis, that sixty out of sixty-two specimens which I killed 

 on an island of the First Cataract were of this species. 



Its plumage differs from T. auritm in the following 

 particulars : — The head is of a pale yellowish brown, lighter 

 beneath, shading gradually on the chest into rich pink, which 

 again fades into white towards the vent ; under taU-coverts 

 white ; the rump and upper tail-coverts broadly edged with 

 yellowish brown ; the exterior web of the outer tail-feather is 

 stained brownish black at a distance of about an inch and a 

 half from the tip ; the two middle tail-feathers broadly edged 

 with yellowish brown, and the two or three next feathers on 

 each side have their white tips partially marked with the same 

 colour ; beak, legs, and irides similar to those of T. auritm. 



Entire length 11-5 inches; culm en 0"7; wing, carpus to 

 tip, 6 ; tarsus 0*8.

The type specimen of this species is in the Berlin Museum, 

 and has been figm'ed by Bonaparte, the original describer 

 (Ic. Pig. t. 102) ; yet Von Heuglin makes no mention of it 

 in his great work on the ornithology of North-eastern Africa. 

 The figure is indifferent ; and as I have not seen the type 

 specimen, and do not know upon what authority its claims 

 are based to be an Egyptian species, I shall refrain from 

 further remarks, merely adding, that if the species is a good
