colouring is not observable. The young of the Griffon Vulture, 
on emerging from the egg, is covered with white down; the 
sides are dark. This bird is known among the Arabs as the

3. Neophron percnopterus. (EgyptianVulture.) 
Though at first sight this bird would appear to be hardly so 
numerous as the preceding species, yet its distribution is so 
much more extensive, that I am inclined to consider it as more 
abundant. It is to be seen usually in pairs; and wherever a 
cliff exists in the mountains that surround the table-lands of 
the Eastern Atlas, sure enough it will be occupied by a pair. 
It was about the 20th of March, when, riding from Tunis to 
Bizerta, I first saw this species, after which this bird and the 
Black Kite (Milvus a ter) were our constant companions through¬ 
out our stay. Generally speaking, the nests of N. percnopterus 
are not so inaccessible as those of Gyps fulvus. One nest which 
I visited near Kef Laks, and from which an Arab had taken 
the egg and broken it, I could reach with my hand from a per¬ 
fectly accessible ledge. This nest was in a crevice of the rock, 
and was composed entirely of small sticks. 
The Arabs used to take the eggs of this bird for us whenever 
and wherever they found them, so that I am unable to speak 
with certainty of the average number laid by one bird; but I 
think that two is the usual complement. In some instances the 
bird would lay again in the nest from which her first egg had 
been abstracted. One nest at Khifan M^sakta contained three 
eggs. The Egyptain Vulture begins to lay about the 10th or 
12th of April. I quite concur in Mr. E. C. Taylor* s remarks 
(Ibis, No. 1 , p. 42) respecting the irides and tarsi of the adult 
of this species ; they agree with my own observations. The 
Arabs are well acquainted with this bird, and call it Bachma , 
the adult being distinguished as tf Bachma batha,” or White 
Bachma. 
4. Aquila chrysaetus. (Golden Eagle.) 
The title of the Golden Eagle to be considered as the King of 
Birds is fully confirmed in the Atlas. Whatever rock a pair 
may choose for their eyrie, there they reign alone in dignified
