NO. 2282. BIRDS FROM SIMALVR ISLAND— OBERHOLSER. 



479 



This bird agrees with the original specimens and shows Macro- 

 pygla sknalurensis Richmond to be easily recognizable as distinct 

 from Macropygia ru-ficepa of Java. It is, however, only a subspecieii 

 of that bird. It differs from Macopyg'm ru-jlceps ruflceps^ wdiich w-e 

 now have for comparison, in its darker pileiim, more extensive!}' 

 rufous chestnut upper wing-coverts, and darker lower parts, par- 

 ticularly the chin, which is scarcely paler than the more posterior 

 areas, instead of tawny buff or even whitish in Macropygia ru-flceps 

 rujiceps. The present specimen shows some indicntions of molt 

 among the contour feathers. 



Family TRERONIDAE. 



MUSCADIVORES AENEUS MISTUS Oberholser. 



]fusr(f(Jivorcs (tenvnf< viisttiN Oiiior.iioT.sEE, Smiths. Misc. ('oil., vol. 60, No. 7. 

 October 26, 1912, p. 2 (Sinialur Island, western Sumatra). 



One adult female, No. 179550, U.S.N.M. ; from Sibabo Bay, Octo- 

 ber 24, 1902. Length in flesh. 397 mm. "Bill leaden, cere dull 

 purple; feet dark purple." 



This example is in fresh plumage, but still shows a little evidence 

 of molt among the outer primaries. It fully agrees with the type 

 and others of the type series of this subspecies. 



The characters that separate Mu^^cadivores aencus mhtus from Mus- 

 cadivores aeneus consohrn/rm of Nias Island, which is clearly a sub- 

 species of Muscadivores ae/neus^ are the shorter wing and somewhat 

 shorter tail of the former, combined with its distinctly more pinkish 

 vinaceous (less grayish) posterior lower parts; usually somewhat 

 paler anterior lower surface ; and, on the average, less reddish bronzy 

 sheen of the green posterior upper parts, though in the last there 

 is considerable individual variation. From Muscadivores aeneus 

 aeneus, of Borneo, the present race may readily be distinguished by 

 its smaller size; much more grayish (less vinaceous) head and lower 

 parts ; less whitish chin and forehead ; and darker lower tail-coverts. 



Measurements of our entire scries from Simalur Island are for 

 comparison given in the subjoined table.
