small spots and rather large blotches of a dirty red, the blotches 
being fewer, larger and more distinct than on the other ege.” 
In the Ibis for 1864, Mr. J. H. Cochrane describes how, on 
the 26th March, 1868, he obtained a nest with four eggs of a red- 
headed Falcon, on the south side of the third or small pyramid 
ef Ghizeh. The nest was a few feathers and still fewer sticks, 
in a hollow on one of the steps, about 30 feet from the top. 
He failed to procure the parent, and so remained uncertain of 
the species; he figures one of the eggs so obtained, it is of 
the yellow brown, Falcon type, and measures 2°17 by 1°71 in 
breadth. But he obtained a second nest from a very similar 
situation. 
“On the 3rd April following, on my return from a fort- 
night’s trip down the Rosetta branch of the Nile, the same 
Bedouin whom I had asked to look out for nests for me, brought 
me a fine living female, Mi/co lanarius, and three eggs, which he 
had taken on the Dashoor Pyramid. The eggs were much 
incubated, and I unfortunately broke one in blowing it. The 
Bedouin said, he had taken the bird by throwing a cloth over 
it at night, and in so doing had broken one of the eggs, which 
originally had been four in number. These eggs much resemble 
those before mentioned.” 
He figures one of the eggs obtained in the latter nest: it is 
of the clouded, brownish red, Falcon type, and measures 2°13 
by 1°55. 
In a later number of the Ibis, this latter egg is put down 
as pertaining to #. Lanarius (verus, I conclude, for Schlegel had 
long previously discriminated between this species and the 
“ Sagr,”’) and the former to “ Barbarus.” Now, although the 
living bird said by the Bedouin to have been captured with the 
egos, is stated to be “alive in the gardens of the Zoological 
Gardens,” and to be “ F. Lanarius,” I confess that I altogether 
disbelieve that these eggs belonged to the two species indicated, 
and entertain little doubt that they pertained to our present 
bird, &. Sacer. In the first place, the size of these eggs agrees 
well, with the authentic egg obtained by Mr. Simpson. In the 
second, there seems an incompatibility between the size of the 
supposed parents and ofthe eggs. EF. Peregrinus is a much larger 
bird than 2. Lanarius, but how seldom do its eggs reach the 
dimensions above given. / Jugger again, is a much larger 
bird than Lanarius, but of the hundreds of its eggs that have 
passed through my hands, the very largest only measured 2°15 
by 1:65, and they average 2°01 by 1:57. F. Barbarus to which 
curiously enough the largest egg is assigned, is the smallest of this 
group of Falcons, and Mr. Salvin gives the following dimensions
