more or less^ interrupted at the shaft by the brown hue of tbe 
rest of tbe feather, which division varies from an exceedingly 
fine margin on each side of the darh shaft, to a broad space 
equal, even in adults, to about xV of an inch. The bars are, 
moreover, irregular, and in many instances do not exactly 
oppose one another, while in others they take the form of 
mere bar-like spots, not reaching to the shaft or margin of 
the web. The brown hue of the feather is uniform through¬ 
out, being no darker at the margin of the white band than 
elsewhere. In contradistinction to these features, the Ceylon 
bird is marked from the chest downwards with broad, com¬ 
plete, parallel-edged, white bands, with which the shaft is 
concolorous; in addition to which the brown portion of the 
feather is not uniform, but has a darker margin bordering the 
bands. The complete band exists in a young bird from 
Haputale in the Norwich Museum, although the only fea¬ 
thers which are barred at all are a few at the sides of the 
breast. The bars, in adults, are continued higher up the 
breast than in any Indian specimens I have seen; and the 
chest-feathers are very deeply indented with white at the 
margins, with the brown portions paler than those of the 
pectoral barred feathers. A further distinctive point in the 
Ceylonese bird is the large foot, with its gigantic claws, that 
of the inner toe being equal to the average hind claw in most 
Nepaul specimens. 
I subjoin the following table of measurements, which may 
be of interest, and which is the result of an examination of a 
series of these Eagles in the British, India, and Norwich 
Museums, showing the relative size of wing and hind claw 
as compared with the same in the island race, which I pro¬ 
pose to distinguish as Spizaetus kelaarti, after its discoverer 
in Ceylon. The list, it will be observed, includes an example 
from Japan, in the Norwich Museum, and which was referred 
to lately by IMr. Gurney in his article on the genus (Ibis, 
1877, p. 431).
