^fZtJ<. ' Very similar to that of E. aqidla, but 'with the white 

 portions of the shafts of the rectrices restricted to the white tip, 

 which on the outer web has a more transverse edge than in the 

 allied form ; the spots on the centre of the feathers of the under 

 surface are all uniform buff. 



This bird varies much as regards the amount of white to the tips 

 of the rectrices, and specimens are not uncommon in which these 

 tips are wanting, whilst others show them on the central feathers 

 only.

Adult. Very similar to that of E. aquila, and, like that form, 

 with the central spots of the abdominal feathers white and not 

 buff as in E. heterura. The tail, however, is like that of E. hete- 

 rura, the white shafts not being continued beyond the white ter- 

 minal spots. 



Mr. Elliot unites this bird with E. aquila, at the same time 

 allowing E. heterura to stand as distinct. All three birds are very 

 closely allied ; but if E. salvini be united to either, it should go 

 with E. heterura and not with E. aquila, the difference of the colour 

 of the spots of the abdominal feathers alone separating them.
