THE BIRDS OF AUSTRALIA. 
Diomedea exulans rothschildi Mathews, New Zealand and East Australian 
seas (Antipodes Island, Auckland Island breeding ; ? Chatham Islands 
breeding). 
It is interesting to note that Solander carefully separated from the Linnean 
D. exulans two varieties, the diagnoses of which I herewith reproduce : the 
largest seems to belong to the bird named by Buber D. “ regia ” : —

Carter {E^nu, Vol. X., p. 295, 1911) noted: ‘‘A fine specimen of Dioinedea 
exulans was received by me ... It measured 3 feet 6 inches in length, 9 feet 
6 inches expanse of wing, and weighed 15 lbs.” This is the only recent record 
of weight I have seen.
