Note on the Eggs of Pagodroma nivea.—The collections officially 
made during the voyage of H.M.SS. Erebus and Terror, were presented to 
the British Museum by the Lords of the Admiralty. Since the above 
list was in type, Mr. Oates, who is now engaged in cataloguing the eggs 
in the Natural History Museum in Cromwell Road, has kindly searched 
on my behalf the collection for specimens of this egg, but he has failed 
to find any eggs of the “white petrel,” or any which “indicate their having 
been obtained at Cockburn Island, or on the 6th January, 1843. It is just 
possible that the eggs collected by Dr. Hooker on that day, and now in the 
Derby Museum, may have been supposed by Sir J. Ross to be those of the 
white petrel, while in reality they are the eggs of the Phalacrocorax atriceps.
