Mr. R. B. Sha7'j)e's Cataloffue of Accipitres. 471 



collection of Messrs. Salvin and Godmau 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 Avhole 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. Sharpens description of which appears to have 

 been taken from an immature specimen, as he describes it as 

 having " the featliers of the back and scapulars white at base.
