Mr. R. B. Sharpe’s Catalogue of Accipitres. 
collection of Messrs. Salvin and Godman differs from the 
adult plumage in the following particulars :—The feathers on 
the crown of the head have faint brown shaft-marks, which 
become broader on the back of the neck, and especially at 
the nape, as well as darker, the marks on the neck being 
slaty black, which is also the colour of the upper ear-coverts; 
some of the scapulars have black shaft-marks, and one of the 
outer scapulary feathers also shows two black marks on the 
external web; the whole of the exterior surface of the wings 
is black, with the following exceptions: the feathers form¬ 
ing the wing-coverts are edged and tipped with white, and 
most of those in the greater and middle coverts are also trans¬ 
versely barred with white; the secondaries are blackish brown, 
transversely barred with black, but tipped with white, and 
also edged with white on the inner web, the innermost secon¬ 
dary showing, in addition, a small white mark on the outer 
web; the outermost tertials resemble the inner secondaries, 
but are rather more spotted with white; the remaining ter¬ 
tials are white, with transverse black bars. 
The character of the black subterminal bar on the upper 
surface of the tail varies somewhat in different individuals. 
A specimen in the collection of Messrs. Salvin and Godman, 
which still retains traces of immature plumage, though to all 
appearance decidedly older than that last described, exhibits 
a remarkable variation in this respect : in this example the 
two central rectrices are entirely white, and on the other fea¬ 
thers of the tail the subterminal band is merely represented 
by a black spot on each side of the shaft; these spots are well 
marked on some of the rectrices, but on the outer pair, and 
also on the pair next the central ones, they are almost ob¬ 
solete; indeed, on one of the last-named feathers only one 
spot is visible, the opposite web being an unbroken white. 
The remaining plumage of this specimen does not appear to 
me to be in any way abnormal. 
The next species to which I propose to refer is Leucopternis 
palliata, Mr. Sharpe's description of which appears to have 
been taken from an immature specimen, as he describes it as 
having “ the feathers of the back and scapulars white at base,
