Specimens from the Paumotu Islands are precisely similar to the 

 Australian specimens in Mr. Gould's collection. 



Relating to this species, the following is given by Mr. Peale : 



" Obtained at Raraka, one of the Paumotu Islands, in the Pacific 

 Ocean. Its flight and general habits are like those of the Noddy, but 

 it does not appear to wander so far from land, and it is perhaps more 

 restricted to the intertropical regions of the Pacific Ocean." 



" We found this bird breeding on Enderby's Island, on the 9th of 

 January, in great numbers. The females lay but one egg each, on the 

 ground, without a nest, and generally under the edge of a rock or 

 bunch of grass. The egg is irregularly spotted with brown, rarely it 

 is entirely white." 



This handsome species is apparently another of the peculiar sea- 

 birds of the South Pacific Ocean, and appears to be rather more re- 

 stricted in its range of locality than is usual in this group. Specimens 

 in the collection are in mature plumage, and present no characters 

 other than as described and figured by Mr. Gould in his Birds of Aus- 

 tralia, above cited.

* " General form, Hglit and graceful ; lead-colored, palest near the bill ; quills darkest; 

 the external web of the first quill black ; secondaries tipped with white ; tail forked, but 

 having the exterior feathers shorter than the next, which are longest; brow black; the 

 posterior half of the eyelids white; irides brown; bill slender, black; inside of the mouth 

 salmon-yellow; legs rather large, black ; the toe-membranes full, yellowish-white; hind 

 toe rudimentary, and having a straight nail."
