Theke are several instances recorded of the occurrence of this beautiful Petrel on the New- 

 Zealand coast ; and the above description is taken from a fine example which I picked up, in a 

 dying state, on the sea-beach near the mouth of the Turakina river, and afterwards presented to 



the Colonial Museum. 



The late Sir Andrew Smith, who was the first to discriminate the characters which dis- 

 tinguish this species from Procellaria glacialis, informs us that it is common on the South- 

 African coasts, and frequently enters the bays— also that it flies higher above the surface of the 

 water than the last-named bird, and rests more frequently.
