We Lave long possessed a specimen of this bird, obtained 

 in exchange from Gould, and there is another exactly like it 

 in the British Museum. The latter was called by Gray 

 FroccUaria phiUipii, he having identified it with the bird 

 so named by himself, the basis of which is the Norfolk- 

 Island Petrel of Phillip^s ' Voyage to Botany Bay ' (p. 161, 



Pl-). 



The colour of the feet and of the primaries justifies the 

 reference of our specimens to Phillips's description ; but the 

 size (16 inches) and the colour make it more than doubtful 

 if the latter really refers to the same bird. The figure 

 represents a bird with a much longer, heavier bill, more 

 like that of one of the (E. fuliyinosa group ; indeed, were it 

 not for the colour of the feet, I should have little hesitation 

 in referring Phillip's bird to (E. solandi, Gould. 



The bird now described at first sight resembles (E. mollis 

 (Gould), but may readily be distinguished by its larger size, 

 darker tail, and especially by having two thirds of the inner 

 web of the primaries, as well as the longest coverts, white. 



Both the specimens before me Avere obtained by John 

 MacGillivray at the Chesterfield Islands, a small group lying 

 a little to the north of west of New Caledonia.

A specimen of P. affinis submitted to me by Sir W. Bullcr 

 agrees accurately with the description of CK. (jularis, and 1 

 have little doubt should bear that name.
