B. bulweri similis sed omnino major, plaga alali cinerascente nulla : rostro et pedibus 

 validioribus, distinguenda. 



This species is closely allied to Bulwer's Fulmar, but may easily be distinguished by 

 its stronger and thicker bill and its longer and stouter legs and feet, as well as by the 

 absence of the greyish patch on the wing-coverts. Macgillivray's Fulmar is only 

 known from a single specimen, procured by Dr. Rayner at Ngau, one of the Fiji Islands, 

 during the voyage of H.M.S. " Herald." As previously mentioned, the late Canon 

 Tristram identified a bird from the Marquesas Islands as B. macgillivrayi, but it was 

 afterwards conclusively proved by Dr. Stejneger to belong to B. bulweri. 



We have as yet no notes on the habits of this species. 



Adult male (type of species). Sooty-black above and below, the throat not being 

 perceptibly greyer than the back, the median and greater wing-coverts wanting the 

 grey patch found in B. bulweri. Total length, 11.2 inches ; culmen, 1.05 ; wing, 8.2 ; 

 tail, 3.35 ; tarsus, 1.3 ; middle toe and claw, 1.6. 



The description and figure are taken from the type in the British Museum.
