Mr. J. H. GURNEY has requested my attention to a specimen of a species of the 
genus Buteo belonging to the Norwich Museum, which I now exhibit. It was formerly 
in the collection of this Society, and was originally received along with other birds from 
the State of Tamaulipas, in Northern Mexico, by Mr. Gould. I have never seen any 
other bird quite resembling it—the nearest ally known to me being the Buteo albono- 
tatus of G. R. Gray, from which, however, on comparison, it appears to be perfectly 
distinct. I agree with Mr. Gurney in considering it as probably undescribed ; and in 
allusion to its nearly uniform sooty-black plumage, propose to characterize it as 
Burro FULIGINOSUS, sp. nov. (Pl. LXIL.) 
Saturate fuliginoso-brunneus unicolor ; capite, dorso medio et alarum primariis extus 
paulo nigricantioribus : primariorum et secundariorum vewillis internis subtus albis, 
sex aut septem vittis nigris transversim notatis ; tectricibus alarum inferioribus nigro- 
brunneis: cauda supra fuliginoso-brunnea, vittis quinque aut sex nigris obsolete trans- 
fasciata et nigro late terminata ; cauda subtus alba et vittis dilutioribus: rostro 
nigro, pedibus flavis. 
Long. tota 15:5, ale 12-0, caude 6:5, tarsi 2°6. 
Hab. In Mexico Boreali.
