490 Mr. J. H. Guruey's Notes on 



webs being speckled with the same ; the primaries and secon- 

 daries are wood- brown, faintly barred with transverse mark- 

 ings of the same colour, but of a darker hue, and slightly 

 tinged with rufous on the inner web ; the feathers on the 

 lower back are of a darker dove-colour^ tipped with rufous 

 and with concealed white bases ; the upper tail-coverts are 

 similar, but many of them are barred with pale luteous, which 

 occupies most of the outer web on the exterior feathers of 

 these coverts ; the upper surface of the tail is crossed by eight 

 dark transverse bars, of which the lowest is broader than the 

 others, subterminal, and distinct ; the three bars above the 

 lowest are edged, above and below, with rusty brown, this 

 being especially observable on the central rectrices ; the inter- 

 spaces between the dark bars are white near the base of the 

 tail, gradually becoming grey as the tip is approached ; the 

 under surface of the tail shows seven indistinct dark bars, with 

 yellowish grej'^ interspaces; the throat is yellowish white, 

 and the whole under surface thence to the vent is a rich 

 buff, varied by darker shaft-marks, which are broadest on the 

 upper breast and flanks ; the tibiae are buff, with narrow trans- 

 verse bars of a darker hue of the same ; the under tail-coverts 

 resemble the thighs, except that the transverse bars are further 

 apart ; the wing-linings are of a very similar character to 

 the under tail-coverts, but the transverse markings are less 

 regular. 



Amongst the birds that in many respects are nearly related 

 to the genus Ui^ubitinga, must be reckoned that scarce and 

 curious species discovered by Tschudi in Peru, and described 

 by him under the name of Cir cactus solitarius, for which tlie 

 late Jules Verreaux subsequently proposed the generic title 

 of Urubitornis, and also that somewhat better known, but 

 also uncommon species. Harpy hallaetus coronafus. 



I agree with Mr. Sharpe that both these birds may very 

 properly be referred to the genus Harpy haliaet us ; but I can- 

 not concur in his view that they should both be referred to 

 the same species, as, although they agree in form and dimen- 

 sions, they differ in H. soUiarms being always (when adult)
