Salve* described CE. cervicalis from a specimen obtained in the Kermadec Islands by 

 Captain Carpenter, of the whaling barque " Costa Rica Packet," and presented by him 

 to the British Museum. It has since been obtained in the same islands by the Earl of 

 Ranfurly, Mr. Cheeseman, and others, and a considerable series procured by Mr. H. 

 H. Travers is in the Rothschild Collection. 



Salvin (I.e.) says that the species is most nearly allied to CE. phwopygia, but is 

 distinguished by its much stouter bill, white hind-neck, and the more distinct grey 

 margins to the feathers of the back. It is also allied to the section of (Estrelata, of 

 which (E. hcesitata is the best-known example, but may be readily distinguished by its 

 larger bill and dark uropygium ; it has, however, the nearly pure white hind-neck of 

 (E. hwsitata, thus differing from (E. phceopygia, but agrees, nevertheless, with that 

 bird in having the dark rump. The size of the bill separates (E. cervicalis from both 

 those birds. A distinguishing feature of these three forms 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 (E. cervicalis are (E. magentas, and (E. externa. 

 But, in the former, the forehead is grey to the base of the bill, and the latter has a 

 longer and thinner bill, the exposed portion of the inner webs of the primaries beneath, 

 near the larger coverts, being white. 



In the " Catalogue of Birds " Salvin lays stress upon the white base to the inner 

 webs of the outer primaries, the length of the wing, and the dark band round its edge. 

 Mr. Ogilvie-Grant, who examined five Kermadec specimens, considers the best
