The Calcutta Museum has lent to me three specimens 

 of U. 0. occipitalis collected by Scully in the Nepal Valley 

 in 1877, and the type of U. a. magnirostr'is from the Yama- 

 dong Hills, Arakan. These examples do not confirm Sharpe's 

 descriptions in the 3rd volume of the ' Catalogue of Birds,' 

 nor Oates's opinion that the latter name has no claims to 

 recognition ('Birds of Burma,' i. p. 401). 



Cat. Birds, pp. 69 and 71. The outer webs of the 

 primaries of magiiirostris are tipped with white and more 

 extensively so than in occipitalis. 



Id. p. 70. There is no pale patch on the inner webs of 

 the lower tail-featliers above the black subterminal band in 

 the Nepal birds, and in stating that it is present in most 

 examples of occipitalis Sharpe may have taken too compre- 

 hensive a view of that race. 



The bill of magnirostris is considerably larger than that 

 of any of the Nepal birds {vide also Hume, ' Stray Feathers,' 

 iii. p. 144), and the white tips of the upper pair of tail-feathers 

 are about half an inch longer. 



The Siamese specimens agree with magnirostris in the 

 length of the white tail-tips, in the presence of pale patches 

 on the inner webs of the lower tail-feathers, in having larger 

 white tips to the outer webs of the primaries, and in the 

 broader subterminal bands to the upper tail-coverts. One 

 of the specimens has the bill of the same length as the type 

 of magnirostris, but scarcely so broad and deep; in the 

 others the bills are smaller and more like those of the 

 Nepal birds ^. 



The under surface, axillaries, inner sides of wings, and 

 edge of naost of the primaries in my specimens are con- 

 siderably tinged with buff. These features are not men- 

 tioned in descriptions hitherto and may only be present in 

 living birds and fresh skins ; they are not to be seen in the 



« The " great uaked space " round the eye of maynirostris (type) ha^ 

 a few scattered feathers therein and is the result of accident or bad 

 preservation, the base of the mandible on one side being also denuded.
