this appears to be the invariable number laid by this Eagle, 
which is one of the most common of the raptorial family in this 
district, arriving about the end of April, and remaining in the 
country till October. The nests, of which we found several, 
were generally placed on the lowest branches of a tall Pine, at 
their junction with the main trunk, and were built of sticks, but 
inside invariably contained fresh twigs with the green leaves 
adhering to them. ‘This Hagle has a shrill piercing scream, 
different from that of any other raptorial bird with which I am 
acquainted.” 
In Spain they appear to lay in the latter part of April, May 
and June. Two of Lord Lilford’s eggs, figured in the Ibis, 
have greyish white grounds; the one has only the faintest trace 
here and there of pale yellowish clouds, the other is more richly 
streaked, clouded and blotched with a dull ferruginous red. 
The former is a rather perfect broad oval measuring 2°05 by 
1:7; the other, a large egg, still a broad oval, but somewhat 
pointed and compressed towards one end, measures 2°25 by 
1:83. 
Of the breeding of a very nearly allied (if really distinct) 
species, H. Morphnoides in Australia, Mr. Gould gives the fol- 
lowing account :— 
“J was led to the discovery of the bird by finding its nest, 
containing a single egg, upon which it had been sitting for 
some time. The nest was of a large size, and was placed close 
to the bole, about one-fourth of the height from the top of one 
of the highest gum-trees ; the egg was bluish white with very 
faint traces of brown blotchings ; two inches and two lines long, 
by one inch and nine lines broad. Very recently I have 
received a second specimen of the egg of this species which, 
although very similar to the one above described, differs in 
being more extensively blotched with yellowish brown and pale 
purple, the latter hue appearing as if beneath the surtace of the 
shell.” 
As to the distinctness of H. Morphnoides, the nidification and 
eggs of which are, it will have been observed, similar in many 
respects to those of H. Pennatus, Mr. Blyth had the following 
remarks in the Ibis for 1867 :— 
“T have already remarked (Ibis, 1866, p. 241) that a rudi- 
mentary crest is always observable in Indian specimens, at least 
I found it soin all which I obtained in Bengal, in one which 
I shot near Moulmein, and in one or two South Indian speci- 
mens received from Dr. Jerdon ; but I cannot perceive a trace of 
rudimentary crest in two mounted Nepal specimens in the 
British Museum, received from Mr. Hodgson. The rudimen-
