occasions seen the young Cuckoo with the young of its foster- 
parents in the same nest. We only obtained the eggs in the 
manner I have stated, and unfortunately left their haunts before 
the young were hatched; our work therefore was left imperfect, 
and it remains the enviable task of some enterprising naturalist 
to unfold the mystery that still hangs over the breeding-habits 
of this bird. For his guidance, whoever he may be, let me add 
that the wooded hills on the south side of Lake Djendeli, and 
in the neighbourhood of the Madracen, both which districts lie 
a little to the eastward of the high-road between Constantine 
and Batna, may be considered as favoured breeding localities of 
Oxylophus glandarius . I have refrained from suggesting any 
probable hypothesis which might clear up the difficulty, as I feel 
sure that before long we shall arrive at the facts of the case, and 
any false supposition might tend to error. 
94. Columba palumbus. (Bing Dove.) 
This Pigeon, which Mr. Gould assures me differs in no way 
from our common Bing Dove, is abundant in many parts, and 
breeds in the month of May.

96. Turtur auritus. (Turtle Dove.) 
Common about Djendeli, where it breeds. 
97. Turtur ^gyptiacus. (Egyptian Turtle Dove.) 
In the Begency of Tunis I observed this bird in many places. 
It is found usually about the towns, and frequents the mined 
Amphitheatre of El Djem. I never saw it in Eastern Algeria.
