Rev. H. B. Tristram on the 
cipices. My specimen I shot in December, near the M'zab 
country, whilst it was being pursued by a party of Ravens. It 
was a male in immature plumage. From the warning I received 
from my guides, I never ventured to offend prejudices by shoot¬ 
ing a second specimen. The careful and able notes of Mr. Salvin 
in the last Number of f The Ibis 3 render it needless to state more 
than merely the occurrence of this bird in the Sahara. 
10. Hypotriorchis subbuteo. (The Hobby.) 
Migratory in the Desert: halting in the Dayats, apparently 
on its passage south. 
11. Tinnunculus alaudarius. (The Kestrel.) 
The Kestrel, identical with that of Europe, although a futile 
attempt was once made to separate it under the name of guttatus, 
probably from the purity of its colours under so bright an 
atmosphere, is abundant in every part of the Desert except the 
plains. In the oases he preys on the Palm Rat (Mus chamce- 
ropsis), which nestles in little communities in the crown of the 
Date-trees, or he pursues the large Scarabcei in the gardens. In 
the rocky f Weds 3 he finds abundance of ‘ Gundi 3 ( Ctenodadylus 
massoni), the Marmot of Africa; and in the Dayats I have often 
watched him pouncing upon the Jerboas as they leave their 
holes. 
12. Astur palumbarius. (Goshawk.) 
I saw one specimen trained for hawking, but never met with 
the bird in a state of nature. 
13. Milvus regalis. (Common Kite.) “ Hadaya Hamra 33 
Arab. 
Abundant in the Dayats, where it breeds on trees, and preys 
upon the various species of Sand-grouse, living apparently at 
peace with the Golden Eagles before mentioned. 
14. Milvus .egyptius. (Egyptian Kite.) “ Essaf” Arab. 
This Kite, which in the Sahara takes the place of the Black 
Kite {M, ater ) of the Atlas, exactly resembles it in all its habits. 
I observed the same contrast between its character and that of 
the Red Kite which exists between the latter and the Black 
Kite. Sociable, fearless, and inquisitive, it approaches man far
