AETHOPYGA SIPARAJA PHOTINA Oberholser 



Aethopyga siparaja photina OBEitHOL;!;Ei5, Siuiths. Misc. Coll., vol. 60, no. 7, 



1912, p. 18 (North Pagi Island). 

 Aethopyga siparaja siparaja Chasen and Kloss, Ibis, 1926, p. 297 (Sipora 



Island). 

 Aethopyga siparaja siheru Chasen and Kloss, Ibis, 1926, p. 298 (Siberut 



Island). * 



Fifteen males and 14 females, Sipora; 4 males, Siberut. 



This race is darker on the average than A. s. siparaja of Sumatra. 



Three out of the four males from Siberut have the feathers of the 

 rump washed with red, giving an orange effect to this region, but ^o 

 has one of the males from Sipora and the type of photina \q identical. 

 I do not see, under the circumstances, any other alternative than to 

 merge siheru with photina. 



After studying and measuring the specimens of this species from 

 Sumatra and the various islands off the west coa^t of Sumatra, I 

 would reduce the recognizable forms from this region to three, as 

 follows : 



(1) Aethopyga siparaja siparaja (Raffles). 



Certhia siparaja Raffles, Trans. Linn. Soc. London, vol. 13, 1820, p. 299 



(West Sumatra).

 Aethopyga siparaja meJanetra Oberholser, Smiths. Misc. Coll., vol. 60, no. 7, 



1912, p. IS (Pulo Lasia). 

 Aethopyga siparaja heliophiletica Oberholser, Journ. Washington Acad. 



Sci., vol. 13, 1923, p. 231 (Pulo Bangkaru, Banjak Islands).

 Lasia, and the Banjak Islands. 



(2) Aethopj/gasiparajaniasensis'H.AiiTERT,OrmthMonsitsh., vol. 6, 

 1898, p. 92 (Nias Island). 



A series of seven males are lighter red above than A. s. siparaja. 

 Range. — Confined to Nias Island, so far as known. 



(3) Aethopyga siparaja photina Obekholser, as given above. 



Range. — Mentawi Islands (Siberut, Sipora. North Pagi, and South 

 Pagi ) . 



'"The range of this form on the mainland is uncertain and the bird there may prove 

 not to be this form at all.
