 claw 41. 



This species is obviously non-migratory, as is evidenced 

 by its comparatively short feeble wings^ wliich are much 

 shorter than in P. tabuensis. In general appearance the 

 species recalls Limnocorax niger (Gmel.), which is widely 

 distributed over Africa, but the latter is of a rather greyer 

 black and has the bill dull green. 



The young in first plumage is rather greyer on tlie throat 

 and ■ underparts than the adult, and has the legs black. 

 Wing 70 mm. 



The nestling is covered with deep velvety-black down. 



The occurrence of this Hail in an island devoid of 

 permanent water is of interest. It inhabits the thiik scrub 

 and is said to be very tame.

Mr. North has described the Fruit-Pigeon from Henderson 

 Island under the above name, and, as he very correctly points 

 out, it difPers from P. coralensis VeaXe from the Paumotu 

 group in having the feathers of the crown deep rose-pink 

 (instead of purplish-pink), the same colour extending to the 

 base of the bill ; the chin and middle of the throat, as well 

 as the vent, white ; and the tail longer. 



Since I published my notes on the Henderson Island 

 Birds in the ' Bulletin^ referred to above. Dr. Richmond has 

 very kindly forwarded to me for examination four examples 

 of the true P. coralensis Peale. They were collected by 

 C. H. Townsend at Makatea, Niau, and Fakarava, all islands 

 lying round Carlsofl' Island in the Paumotu Group, where 

 the type of P. coralensis was obtained. The only example 

 of that species in the British Museum is the type of 

 Ptilopus chalcurus Gray, an immature bird said to have 

 come from Hervey Island, as is mentioned below.
