Ad. Omnino fuliginoso-niger, gutture pallidiore : subtus brunneo lavatus : rostro et pedibus nigris : iride nigra. 



Adult. Entire plumage sooty or brownish black, paler on the throat, and tinged with brown on the under- 

 parts. Irides, bill, and feet black. Total length 17 - 5 inches; wing, from flexure, 12*5; tail 5; bill, 

 following the curvature of upper mandible 1*75, length of lower mandible 175 ; tarsus 1*5 ; middle toe 

 and claw 2*4. 



This species, which ranges over both the Atlantic and the Pacific Oceans, inhabits the seas all 

 round New Zealand, but seldom approaches the land. If I was right in my identification of 

 those observed on the wing during a passage from Auckland to Sydney in July 1871, this Petrel 

 is a remarkably powerful flier, coursing about with the activity of a Martin, and generally near 

 the surface ; but it is almost impossible to distinguish the various allied species with any 

 certainty by merely observing them from the deck of a ship.
