lighter in colour, the feathers of the upper part of the head
and neck lanceolate ; the primaries almost black ; under surface
of the body very little lighter in colour than the hack ;
all the feathers white at the base ; legs, toes and claws as in
the young birds.
The whole length twenty-seven and a half inches, the wing
from the anterior joint twenty-three and a half inches ; the
fourth and fifth quill-featliers nearly equal in length, but the
fifth rather the longest in the wing. The wings when closed
reach to the end of the tail.
According to Professor Schlegel, Aquila ncevia can he distinguished
by its round and small nostrils from A. clanga,
in which they are wider and elliptical. The same higli
authority also thinks that the white markings on the wings
are not indicative of age, but simply individual peculiarities,
adding, that an example in the Museum of Leyden, brought
up from the nest, and known to have moulted three times,
retained the spots with which it was originally adorned.—
