250 Mr. W. Raw on the [Ibis, 
at the British Museum, and refer them to the above sub¬ 
species. 
49. Phylloscopus trochilus. Willow-Warbler. 
Numerous in spring, but less so in the autumn. 
50. Phylloscopus bonelli, Bonelli’s Warbler. . 
Seen occasionally feeding in the sont-trees in both spring 
and autumn. Specimens obtained. * 
51. Phylloscopus sibilatrix sibilatrix. Wood-Warbler. 
Observed only in the spring except a single specimen 
seen on 11 September, 1917. Abu Zabal was not an ideal 
spot for observing the autumn migration, as I am certain 
many species rested near the coast and passed over Abu 
Zabal in the next lap of their journey. 
[Phylloscopus s. erlangeri ? Edanger’s Wood-Warbler. 
On 17 April, 1916, I saw a bird which I believe was 
referable to this subspecies. It was in my garden, but I 
did not shoot it as I had hopes of trapping it alive.] 
52. Locustella luscinioides luscinioides. Savi’s Warbler. 
Large numbers were observed roosting in the reed beds of 
the old canal in April 1917. 
53. Acrocephalus arundinaceus. European Great Reed- 
Warbler. 
I believe this species may occur at Abu Zabal, although 
I never secured one there. I did, however, shoot a specimen 
at Inclias, not far distant, in the spring of 1918. 
54. Acrocephalus stentoreus stentoreus. Clamorous Reed- 
Warbler. 
Common and resident in the reed-beds on the Birket 
Accrashi. I found the eggs of this bird on 11 May, 1916. 
Some were 75 per cent, incubated, others fresh, and I found 
several uncompleted nests on the same day. Fresh eggs 
and young birds were also observed in the Wadi Natrun 
late in May 1918.
