so that they can be recognised at sijjht : their habits are 

 different, and their notes differ essentially so that even in the 

 dark they can be distinguished. 



Neonectris griseus pescadoresi, subsp. n. 



Two specimens, labelled " Pescadores Is., May 1909, 

 Pu^nus carneipes Gould /^ are the first record of this species 

 from the western Pacific Ocean and also the first record of 

 the species as a breeding bird north of the Equator. These 

 two birds were taken from breeding-burrows, and have tlie 

 base of the bill somewhat denuded of feathers through 

 digging. The fact that Owston labelled them " Pvffinus 

 curneipes^^ indicates the nature of the bill, as that species 

 has a heavy bill and flesh-coloured legs : these specimens 

 have not flesh-coloured legs but have stout bills, which 

 characterise the subspecies. 



The birds are brownish above, the head black ; there are 

 brownish tips to the scapulars and greater wing-coverts ; 

 chin ashy ; under surface ashy brown, paler on the breast; 

 axillaries brown ; the under-wing feathers ashy with dark 

 shafts. There is practically no diffierence whatever in the 

 two specimens, the paler breast being rather more pro- 

 nounced in one bird, which has also the under wing-coverts 

 lighter.

The type-locality of Neonedris griseus (Gmelin) is New 

 Zealand, where in the extreme south it is an extremely 

 abundant breeder. One of the writers has seen them in 

 countless numbers passing to the breeding-ground so often 

 written about. Neozelanic specimens show little difference 

 in the measurements save in the bill, which is short and 

 more slender, an average example measuring : — Culmen 39, 

 wing 290, tail 87, tarsus 56, mid-toe 54 mm.
