Mr. R. B. Sharpe’s Catalogue of Accipitres. 48] 
those of the adult female have, in fact, been taken from a ° 
large male, as a female from Venezuela in the Norwich Mu- 
seum is considerably larger in the wing, measuring 10:2 inches 
from the carpal joint. 
This female is nearly adult, but retains some interesting 
remains of immature plumage, the axillary feathers being alter- 
nately barred transversely with white and blackish brown, 
whilst the tips of these feathers exhibit a guttate shaft-mark 
of the latter colour, surrounded by an edging of yellowish 
white; the tibiz are almost entirely black on their external 
face, but on the opposite side of the limb are transversely 
barred with irregular alternate markings of blackish brown 
and buff; aslight tinge of rufous is just appearing at the lowest 
extremity of the tibial feathers ; the upper surface of the tail 
still shows two ashy brown bars; and the lining of the wing 
near its external edge exhibits a greater proportion of black 
than is to be found in older birds. With these exceptions, 
and that of a sight fulvous tint upon some of the feathers of 
the breast, the specimen has completed the assumption of the 
adult dress. 
The next group to which I would refer, and to which I 
would restrict Kaup’s subgeneric name of Rupornis, consists 
of the following species, or, as they may perhaps be more ap- 
propriately termed, geographical races :— 
The most southern of these is R. ee inhabiting 
S.E. Brazil, Paraguay, Buenos Ayres, and the Argentine 
Republic. 
Mr. Sharpe has included Bolivia in the localities which he 
gives for this species; but the Bolivian race appears to be di- 
stinct, and, subsequently to the publication of Mr. Sharpe’s 
volume, has been so described by Messrs. Sclater and Salvin 
under the name of “ Asturina saturata”’ in the P. Z. 8. 1876, 
p. 357. 
A somewhat more northerly range characterizes R. nat- 
tereri, which appears to be very generally distributed through- 
out Brazil, extending westward to Peru; whilst the most 
* The iris in this species has been recorded by Mr. Lee as being of a 
“very pale amber-colour ” (vide Ibis, 1873, p. 136).
