176 LIST OF DIURNAL BIRDS OF PREY. 



leaden; apex and cere blackish; legs greenish yellow, but 

 pale brown on the toes; claws dark brown. '^ 



Specimen No. 1, which from its small size must, I think, 

 undoubtedly be a male, bears a remarkable resemblance to 

 No. 3, from which its coloration only differs in having a more 

 decided gular stripe formed by the markings on the feathers 

 of the throat, in most of the concealed light transverse bars 

 on the breast being a pure white, in the absence of any 

 tinge of rufous on the upper surface, and in having only 

 five dark transverse bars on the central rectrices. 



Specimen No. 2, which is probably also a male, has unfor- 

 tunately been badly skinned, and portions of the nuchal and 

 abdominal plumage are wanting; but it appears only to 

 differ from No. 3 in the markings on the throat being more 

 tinged with grey, and in the dark cross bars on the thighs 

 being brownish grey instead of rufous; also in those of the 

 axillaries being browner and less rufous, and in the upper 

 surface of the body and wings being of a more slaty black 

 hue, with even less tinge of rufous on the nape and none on 

 the least wing-coverts ; like No. 1, it has but five dark cross 

 bars on the tail. 



No. 4 is the largest specimen of the series, and I therefore 

 consider it to be undoubtedly a female ; it agrees generally 

 with No. 3, and especially in having six dark transverse bars 

 on the tail ; but it differs from it in the following particulars : — 

 all the upper surface is slightly browner, and with no tinge 

 of rufous on the nape ; the gular stripes are more strongly 

 marked; the white transverse bars on the jugulum and on 

 the breast are not concealed, and are a purer white and more 

 numerous than in No. 3, there being two white bars on each 

 feather of the breast, besides a white base ; the axillaries 

 agrree in tint with No. 2. 



The following is a copy of the description given by Lord 

 Tweeddale in his paper in the ' Proceedings of the Zoological 

 Society^ for 1878, to which I have already referred, of the 

 two nestlings, presumably of this species, which were sent 

 over by Mr. Everett at the same time as No. 3 : — " Nestlings 

 in rufous dress; underneath creamy fulvous, with broad
