On comparing these measurements with those of C. cine- 
rascens, it will be seen that the two species are nearly iden¬ 
tical in size, but that the average length of the tail is slightly 
greater in C. fasciolatus. 
In their markings, however, the two species are very dis¬ 
tinct ; thus, in C. fasciolatus j the white transverse bars on 
the lower breast, abdomen, and thighs are mueh broader than 
in C. cinerascens, the white edgings to the upper tail-coverts 
mueh more conspicuous, and the arrangement of the trans¬ 
verse bars on the upper surface of the tail entirely diflPerent, 
the conspicuously wide white or whitish spaee stretehing aeross 
the middle of the tail in C. cinerascens being absent in C. 
fasciolatusf in which species the tail is crossed by from four 
to five dark bars, with intermediate paler spaces, all of whieh 
are much more nearly equidistant from each other than is 
the ease with the bars aeross the tail in C. cinerascens. This 
distinetion may be readily perceived by eomparing the figures 
of the two species, which will be found in ^ The Ibis for 
1860, pi. XV., and in that for 1862, pi. iii. 
In ^ The Ibis ^ for 1861, at p. 130, I mentioned that in 
Circaetus fasciolatus the anterior part of the inside of the 
wing adjacent to the earpal joint is transversely marked with 
brownish grey bars,^^ alternating with white ones, instead of 
being white as is the case in the adult of C. cinerascens. 
This deseription applies to the two specimens in the Norwich 
Museum, and also to the two in the possession of Captain 
Shelley; but in Mr. Sharpens description of the type speeimen 
in the British Museum it is said that the under wing-coverts 
are white, with a few markings of pale brown,^^ from which
