BULWERIA BULWERL 



B. macgillivrayi, but Dr. Stejneger examined the specimen, and had no doubt that it 

 was B. bulweri. Dr. H. O. Forbes kindly sent this bird to me for examination, and I 

 fully concur in Dr. Stejneger's determination. 



The nest is usually concealed under boulders, or in holes in the rocks, where a 

 few old bones or feathers of a Tern frequently supply the place of sticks or grass for 

 the nest. Here the single white egg is laid, though Mr. Fisher relates that on one 

 occasion on Necker Island two eggs were found in the same hole, possibly belonging 

 to different birds. 



Adult. Above sooty-black, rather paler beneath ; chin and throat tinged with 

 grey ; the greater wing-coverts greyish brown, forming a distinct patch. Bill black ; 

 iris dark brown; tarsi and feet blackish, except the outer third of the webs, which is pale 

 flesh colour ; tail cuneate ; wing, 1.75 ; tarsus, 1.05-1.1 ; middle toe and claw, 1.15-1.35 ; 

 culmen, .85-. 95. 



The description is taken from a bird procured by Mr. Ogilvie-Grant ; the figure 

 is from a Madeira specimen from our collection, now in the British Museum.
