178 Mr. J. H. Gurney on an unusually rufescent 



with white ; the upper tail-coverts nearest to the body arc 

 greyish white^ with slaty black transverse bands ; those next 

 the tail are pure white, with transverse bands similarly 

 coloured but narrower ; the upper surface of the tail is white, 

 crossed by narrow dark grey bars, twelve in number on the 

 central, and fourteen on the exterior pair of rectriccs ; below 

 the lowest of these transverse bars are three subterminal 

 bands, the uppermost white, the next and broadest black, and 

 the third grey, the tip of the tail being white. 



The cheeks, chin, and throat are a dark slate-colour, as is 

 also the region of the crop, with the exception, as regards 

 the latter, of irregular white tips to some of the feathers ; the 

 breast, abdomen, flanks, tibiae, and under tail-coverts, as also 

 the under wing-coverts and axillary plumes, are all alternately 

 barred with transverse markings of white and slate-colour, 

 this barring is finer and less coarse on the tibise than else- 

 where, and is most regular on the under wing-coverts, the 

 white predominates on the under tail-coverts, and the slate- 

 colour on the breast ; but it is there mingled, on many of the 

 feathers, with rich rufous, and these particoloured feathers 

 are only slightly tipped with white ; a faint tinge of rufous 

 also appears on some of the feathers of the abdomen. 



XIV. — Note on an unusually rufescent Example 0/ Arcliibuteo 

 hemiptilopus, Blyth. By John Henry Gurney. 



A SPECIMEN of Archibuteo hemiptilopus* having been lately 

 added to the Norwich Museum, which presents a much more 

 rufous aspect of plumage than any example which had pre- 

 viously come under my notice, I think it desirable to place 

 some particulars respecting it on record in the pages of 

 ' The Ibis.' 



It was obtained in Thibet in September 1874, and passed 

 into the hands of Mr. Mandelli, and from him, by exchange, 

 into those of my late valued friend Mr. Andrew Anderson, 

 upon whose decease it was acquired by the Norwich Museum. 



* I use Mr. Blyth's specific name for this Buzzard for the reason which 

 I have ah-eady given in 'The Ibis' for 1876, p. 371.
