474 On a new Hawk from Bouru. 



has kindly sent. Judging from it, I have not the least doubt 

 that Mr. Sharpe was quite right in considering the bird as 

 belonging to a new species, which, in my forthcoming work, 

 ' Ornitologia della Papuasia e delle Molucche,^ part i. p. 64, 

 I have already named Urospizias pallidiceps. Unfortunately 

 Prof. SchlegeFs full description arrived too late to be inserted 

 in my work, where I have described the bird from SchlegeFs 

 '^Notes,^' so that I think it convenient to publish now the 

 more full description for the benefit of ornithologists. I shall 

 add the quotations which, according to me, belong to this 

 new species.

The light greyish-white colour of the head and neck to the 

 middle of the mantle makes this Bouru bird easily distin- 

 guishable from any allied species. I should say, from the 

 deep uniform rusty colouring of the underparts, that its 

 nearest ally is U. iogaster (Miill.), from Amboyna and Ceram.
