316 Mr. O. Salvin' s Five Months' Birds'-nesting 
92, Cuculus canorus. (Cuckoo.) 
In the Waregra country, near Sidi Youssef, towards the end 
of March I saw several Cuckoos, one of which I shot. I have 
no recollection of having either met with it or seen it subse¬ 
quently. 
93. Oxylophus glandarius. (Great Spotted Cuckoo.) 
Mr. Hewitson, quoting Mr. Tristram, has given an account of 
the breeding of this bird (vide ‘Ibis/ vol. i. p.76), to which a few 
additional remarks of my own may not be here out of place. I 
was unfortunately the one of the party that saw least of this bird; 
therefore I can only add a little information as to the manner in 
which our eggs were obtained, and, I am sorry to say, nothing to 
the general habits of the bird. I first observed it in the Waregra 
country, near the Tunisian frontier, after which we lost sight of 
it till the middle of May, when our attention was drawn to the 
fact of its existence in the neighbourhood in which we were then 
located, by the information brought by Mr. Tristram from Batna. 
On the morning of the 20th of May, an Arab brought us two 
eggs which corresponded so well with the egg Mr. Tristram had 
previously obtained, that our expectations were raised to the 
highest pitch. A few hours after, another egg was brought from 
another quarter ; and in the evening of the same day, four more. 
With none of these eggs were any of the Pica mauritanica . On 
blowing them, the first two proved to be about half-incubated, and 
the zygodactylic structure of foot was clearly visible; the others 
were fresh. I may add, that on taking each of the Arabs to my 
box of skins, each separately selected a Common Cuckoo, and 
showed wherein the Great Spotted Cuckoo differed. There was 
no skin of O. glandarius in the box. On the 20th of May, 
therefore, we had no doubt that we had the eggs of this Cuckoo. 
On May 25th, Mr. Simpson was taken, by an Arab who had 
been in the habit of collecting for us, and who lived in a camp 
not far from ours, to a nest, in which he found three eggs 
corresponding exactly to those we had previously obtained. Mr. 
Simpson did not see the birds near, and at the time supposed, 
from the fact of the nest being so close to the Arab tents, that 
the eggs had been put there by the man who showed it to him,
