Rev. H. B. Tristram on the 
seems partially to take the place of the Spectacled Warbler. I 
have seen it in localities where I should not have expected to 
find its congener, on the great plains where there were no shrubs 
or plants. It differs from the former in the colour of the top of 
the head, which is rufous instead of ash colour, and in the throat, 
neck, breast, and belly, which are of a uniform pale sand-colour, 
while the Spectacled, besides its whiter chin and dark throat, has 
a rich vinous tint down the whole of its flanks. Similar as the 
two birds are in winter dress, I can feel no hesitation as to the 
distinctness of these species, having frequently obtained both in 
neighbouring or the same localities at the same time of the year. 
I was unfortunately unable to visit the haunts of S. deserticola 
in the breeding season. 
55. Melizophilus provincialis. (Dartford Warbler.) 
Abundant in winter in the dayats, but never approaching the 
oases or the habitations of man. I do not believe that it is 
sedentary in the Sahara, but retires to the mountains to breed. 
I have taken several nests in the Atlas in the months of May 
and June. 
56. Phylloscopus trochllus. (Willow Wren.) 
57. Phylloscopus rufus. (ChiffchafF.) 
58. Phylloscopus bonellti. (BonellPs Warbler.) 
Abundant in the oases in winter, but retiring northwards at 
the end of February. The ChiffchafF especially assembles in 
thousands in the palm groves of EP Aghouat. The Arab name 
for all three species is “ Millil 
59. Cettia sericea. (CettPs Warbler.) 
60. Hippolais polyglotta. (Melodious Willow Wren.) 
61. Hippolais pallida, Gerbe. (Pale Warbler.) 
Is not this identical with Sylvia ela'ica of Lindermayer ? It 
is found in the marshes about Tuggurt in considerable abun¬ 
dance, and I have taken many nests south of the Atlas. 
62. Calamoherpe turdoides. (Great Sedge Warbler.) 
63. Lusciniopsis savii. (SavPs Warbler.) 
The former seen and heard, the latter heard, frequently du=
