PEOCEEDINGS OF THE NATIONAL MUSEUM 



VOL. 75 



From the above, in my opinion, we can recognize three forms at 

 present from the islands off the west coast of Sumatra, as follows : 



(1) Maci'opygia eniiliana hypopercna Oberholser, confined to Sima- 

 lur Island ; 



(2) MaxTOfygia emMiana modiglianii Salvador!, confined to Nias 

 Island; and 



(3) Macropygia emiliana elassa Oberholser, from Siberut, Sipora, 

 North and South Pagi Islands. No specimens have been available 

 from Engano. 



The measurements (in millimeters) of the specimens from the dif- 

 ferent islands are as follows : 



Eight males from Siberut 



Ten males from Sipora 



Two males from the Pagi Islands 



One male from Nias 



Six females, Siberut 



Seven females, Sipora 



Five females, Pagi Islands 



Three females, Nias 



One (female?), Simalur

CHALCOPHAPS INDICA INDICA (Linnaeus) 



Columba indica Linnaeus, Syst. Nat., ed. 10, 1758, p. 164 {India orientali). 

 Chalcophaps indica indica Chasen and Kloss, Ibis, 1926, p. 275. 



One female, Siberut Island; the United States National Museum 

 also has an immature female from North Pagi Island. 



RALLINA FASCIATA (Baffles) 



Rallus fasciatus Raffles, Trans. Linn. Soc. London, vol. 18, 1922, p. 328 



(Sumatra). 

 Rallina fasciata Chasen and Kloss, Ibis, 1926, p. 276. 



One male, Sipora. 



The one male taken on Sipora does not seem to differ in size or 

 color from specimens from other parts of the specific range. The 

 Museum also contains a male from Engano Island; rather more 

 hazel above and heavier barred below than usual, but it can be 

 matched by a male from Trong, Lower Siam, so the differences are 

 doubtless individual. 



AMAURORNIS PHOENICURA CLEPTEA Oberholser 



Amaurornis phoenicura cleptea Obebholsee, Smiths. Misc. Coll., vol. 60, 



No. 7, 1912, p. 2 (Mojeia River, Nias Island). 

 Amaurornis phoenicura javanica Chasen and Kloss, Ibis, 1916, p. 276. 



One male, Siberut ; three adult males, one immature male, and four 

 females, Sipora.
