$28 Notes on Mr. R. B. Sharpe’s Catalogue of Accipitres. 
some of the tibial feathers, also on the wing-coverts, axil- 
laries, flanks, and abdomen; on some feathers of the under 
tail-coverts faintly rufescent broadened shaft-marks are per- 
ceptible; on all the remainder of the under surface, consisting 
of the entire breast and throat, the shaft-mark on each fea- 
ther is expanded into a broad blackish-brown patch occupying 
the whole of the feather, except a narrow edge and the base, 
which are white, but not conspicuously so. 
In No. 12, a female, also from Chiriqui, broadened shaft- 
marks, like those on the breast of No. 11, extend over the 
entire under surface; but on the under tail-coverts they are 
of a decided rufous brown, instead of being blackish brown, 
as elsewhere. Except for the lack of the rufous collar, this 
specimen would closely resemble Temminck’s plate (Pl. Col. 
270). An example from Honduras, very similar to No. 12, 
is preserved in the British Museum. 
I may also here mention two specimens in the collection 
of Messrs. Salvin and Godman, which I may call Nos. 13 
and 14, and which have attained the adult dress, with the 
exception of some slight remains of earlier plumage, that 
seem to be relics of the darker phase of immature colouring. 
No. 18 is a male from Venezuela, which retains one dark 
feather on the breast, others, partially dark, on the sides, 
and several brown secondaries in the wings; while in No. 14, 
from Guatemala, most of the tibial feathers are of a blackish 
slate-colour, mingled with pale grey, and a few feathers of 
the flanks are similarly tinged, though to a less extent. 
Mr. Sharpe does not mention the colour of the iris in this 
species, which, according to other authorities, is lable to con- 
siderable variation. 
The nearly adult male frum Venezuela, No. 13 in the above 
list, is marked by the collector as having the iris yellow ; but 
an adult male from the same locality in the Norwich Mu- 
seum is similarly marked as having the iris brown ; it is also 
noted by the collector as light brown in a white-breasted 
immature male in the same collection, the locality of which 
is unknown.
