 (type from Sulu Island). — Chasen and Kloss, Ibis, 1926, p. 296. 



One female, Sibenit, September 20; one female, Sipora, October 11. 

 The above two specimens are Youn<^ birds: they agree fairly well 

 with northern Celebes specimens in the same stage of plumage.

(Sipora). 

 Chalcostetha calcostetha siberu Chasen and Kloss, Ibis, 1926, p. 297 



(Siberut). 



Five males and four females, Sipora ; one male and two females, 

 Siberut. 



The tAvo females from Siberut are paler than those from Sipora. 

 but a female from North Pagi Island exactly matches them. There 

 is no difference in size. I am inclined to think the deeper color of 

 the Sipora females is due to the fresher condition of the plumage. 

 They were collected in middle or late October, while the Siberut 

 females were collected in middle or late September. One female in. 

 the Sipora series, collected October 21, is somewhat worn and is 

 .nlmost, if not quite, as pale as Siberut females. Specimens from 

 Nias and the Batu Islands do not appear to differ from those from 

 the Pagi Islands. If any form is to be named, it would be that 

 from Sipora; but this would divide the habitat of pagicola, so I do 

 not believe it advisable to provide a name for it on the material at 

 hand. 



Specimens from Simalur Island are larger than fo-gicola^ especially 

 the bills. It has been named Chalcostetha calcostetha heliomarpta 

 Oberholser.^** 



From the islands off the west coast of Sumatra there are two 

 recognizable forms, judging from the material before me, as follows :
