One specimen. 



Mr. Salvin, to whom I sent the specimen for comparison, kindly 

 writes to me : — " Compared with a specimen of Procellaria neglecta, 

 Schl., in my collection from the Kermadec Islands, the head is a 

 little lighter ; and it has rather more white on the base of the wing- 

 feathers than a specimen from the same collection as the type of P. 

 neglecta, Schl. The bill slightly longer. Not otherwise different 

 in my opinion." 



As the white basal portion of the plumage, so conspicuous chiefly 

 on the inner web of wings, is not mentioned by Prof. Schlegel, and 

 on account of the rarity of this species, I think it better to give a full 

 description. 



In form tliis species, with its stout bill, seems nearest allied to P. 

 fuliginosa, Kuhl. On account of the mottled appearance the spe- 

 cimen looks like an immature bird ; and the suggestion may be 

 allowed that the old bird will have the head, neck, and underparts 

 uniform white. 



Head, neck, and under surface white, nearly all the feathers washed 

 at the tips with pale brownish, giving the head above, the neck, 

 and the sides of the body a pale brown wash ; front, sides of head, 

 throat, and middle of the underparts more pure and uniform white ; 

 under tail-coverts brown, with white basal portion ; back, shoulders, 

 wing-coverts, and remainder of upper parts dark brown, each feather 

 white at the basal half, some of the shoulder- and smaller wing-
