82 CASPIAN BIFASCIATED EAGLE. 
that the bird was an immature Aquila Jteliaca. 
The Caspian Bifasciated Eagle makes its nest in the Dobrudsha on 
the ground, generally at the foot of some large rock, and lays two, 
sometimes three, eggs. I have in my private collection a series of 
the eggs of this bird. Of these I must now take out three, since the 
parent bird has been declared by Mr. Gurney and Mr. Dresser to be 
an immature A. heliaca. These eggs measure — 
1. Two inches and three fourths by one inch and seven tenths. 
2. Two inches and a half by one inch and seven tenths. 
3. Two inches and a half by one inch and eight tenths. 
They are, one quite white, and the other two blotched with rufous 
and reddish purple. 
Of the true Aquila orientalis I have 
1st. — Two from the nest on which the bird was trapped that I sent 
to Mr. Brooks in India, and which he identified as Aquila bifasciata. 
They are alike in size, and measure two inches and six tenths by 
one inch and nine tenths. They are more thickly blotched with rufous 
and indistinct (washed out) purple. As will be seen by the one I 
figure, they only differ from the other Imperials in being smaller, and 
the blotches more numerous. 
2nd. — Six eggs taken in Southern Russia by Herr Glitzch, and sent 
to me by Von Heuglin. They measure respectively two inches and 
seven tenths by one inch and nine tenths, two inches and six tenths 
by two inches, two inches and seven tenths by two inches, two inches 
and eight tenths by two inches and one tenth, two inches and eight 
tenths by one inch and nine tenths, and two inches and eight tenths 
by one inch and nine tenths. Of these, five are more or less blotched 
with rufous and indistinct purple. In one the thicker end is almost 
covered with dark purple, and one is quite white with the exception 
of here and there a small purple spot. 
The second egg figured under the sign of (?) is one of the two 
eggs taken from the nest of the Striated Eagle, figured by Mr. Dresser 
as Aquila mogihiik, (Juv.) Birds of Europe, part 19, pi. 152. 
My figure of this bird is taken from a specimen taken as a typical 
one from the Norwich Museum by Mr. Gurney, and drawn for me 
— for which I express my best thanks — by Mr. Reeve.
