Tlie specimen from which the above description is taken 

 was recently sent to the British Museum by Captain Car- 

 penter of the whaling barque ' Costa Rica Packet/ with 

 the information that it was obtained " about a year and a 

 half ago " on the Kermadec Islands. The bird is evidently 

 allied to the section of (Estrelata of which CE. hcBsitata is the 

 best known example. From this species it is readily distin- 

 guished by its larger bill and its dark uropygium, but it has 

 the nearly pure white hind neck of CE. hasitata ; in this it 

 differs from (E. phaopygia, but agrees with that bird in 

 having a dark rump. The size of the bill separates it from 

 both these birds. 



A character by which these three birds may be distinguished 

 is the colour of the primaries beneath^ which are black over 

 the whole of the exposed portion of the inner webs, and only 

 become white under the larger coverts. 



Other species of (Estrelata allied to CE. cervicalis are CE. 

 magentce and CE. externa. But in the former the forehead is
