384 Mr. W. Raw on tlie [Ibis, 
Hydrochelidon hyhrida (= leucopareia ) at Abu Zabaal, but I 
never met with it there myself. 
217. Larus ridibundus. Black-headed Gull. 
Observed only twice at Abu Zabaal. Two seen together 
on 17 January, 1918, and a single bird shot on 30 December, 
1917. 
218. Megalornis grus. Common Crane. 
On 30 April, 1918, I saw a large flock of Cranes flying 
over Abu Zabaal. They were going due north. 
219. E,alius aquaticus aquaticus. Water-Rail. 
There can be little doubt that this species is a resident in 
the vicinity of Abu Zabaal, but the good cover lends itself 
to the Water-RaiTs skulking habits. I shot a specimen on 
30 December, 1916, and have seen and heard it on numerous 
occasions, but never found a nest there. As a breeding-bird 
it is very common in the Wadi Natrun, and Major F. W. 
Borman and I found three nests, with hard-set eggs, there 
on 27 May, 1918. These nests were all found within a 
hundred yards radius, and were in a dense reed-bed. They 
contained six, seven, and eight eggs respectively. 
[This species nests at Inchas, and probably in many suit¬ 
able localities in the Delta. My dates are: Two eggs, 
addled, 30. iii. 10 ; five eggs, fresh, 15.vi. 09; four eggs, 
fresh, 10. iv. 10 ; so that it is probably double-brooded.—

220. Porzana pusilla intermedia. Baillon’s Crake. 
In addition to the specimen mentioned below, as having 
been shot on 19 April, 1917, I only secured one more, 
namely, a bird shot on the Birket Accrashi, on 3 October, 
1917. It is my opinion that both species breed in the 
Egyptian delta. 
221. Porzana parva. Little Crake. 
I first met with this species on 12 October, 1916, when I 
shot a specimen on the Birket Accrashi. I shot a second 
specimen there on 20 October, 1916, and on 28 December,
