PROCELLARIA BULWERII, (nobis). 

 Bulwers Petrel. 



PLATE LXV. 



P. niger, subtus brunnescens, cauda cuneata. 



"We are indebted to the kindness of Mr Bulwer, during some years a re- 

 sident in Madeira, for the subject of this plate, which we consider as yet 

 undescribed. It is not to be found in the works of Latham or Shaw, or 

 indeed in any other which we have had an opportunity of consulting ; and, 

 from its marked characters, it is not a species that would be easily over- 

 looked. The length of our specimen is about ten inches : it will come un- 

 der that division of the group where the nostrils are contained in one tube, 

 but have a division between them. The plumage is entirely of a deep 

 sooty black, paler upon the throat, and on the breast and belly slightly 

 tinged with brown. The form of the tail is the greatest peculiarity ; this 

 contains twelve feathers, and is very much cuneated, the centre plumes 

 being above two inches longer than the exterior, thus giving us a form at 

 variance with the smaller and true Petrels, where we find it either square 

 or forked. 



It inhabits Madeira or the small islands adjacent.
