250 Mr. W. Raw nn 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 occnsionally feeding in the sont-trees in both spring 

 and autumn. Specimens obtained. 



51. Phylloscopus sibilatrix sibilatrix. Wood-Warbler. 

 Observed only in tjie s})ring except a single specimen 



seen on 11 September, 1917. Abu Zabal Avas not an ideal 

 spot for observing the autumn migration, as I am certain 

 manv species rested near the coast and passed over Abu 

 Zal)al in the next lap of their journey. 



[Phylloscopus s. erlangeri ? Erlanger'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. Acrocephahis 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 Inchas, not far distant, in the spring of 1918. 



54. Acrocephahis stentorens stentoreus. Clamorous Eeed- 



Warbler. 

 Connnon and resident in the reed-beds on the Birket 

 Accrashi. I found the eggs of this bird on 11 May, 1910. 

 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 Natrim 

 late in May 1918.
