BANGS AND PENARD : SOME CRITICAL NOTES ON BIRDS. 25 



The name which has so universally been used for Temminck's 

 Sapphire-wing unfortunately cannot prevail on account of preoccupa- 

 tion, and Fraser's cyanoptenis appears to be the first available for it. 



Synallaxis brachyurus brachyurus Lafresnaye. 



Synnalaxis hrachyurus Lafr., Rev. zooL, 1843, p. 290 (Colombia). 



Type.— M. C. Z. 77,256, Lafr. coll. 2,456. 



SynaUaxis pudica Sclater, Proc. Zool. soc. London, 1859, p. 191 

 (Bogota). 



We have carefully coiiipared the type, an immature bird with a 

 short, undeveloped tail, with the various forms of Synallaxis pudica 

 and with SynaUaxis svbpndica Sclater. We find Synallaxis pudica 

 Sclater identical with <S. hrachyunis hrachyurus Lafr. 



The subspecies now become : — 



Synallaxis brachyurus brachy^irtis Lafresnaye. 



Synallaxis brachyurus nigrifumosa Lawrence. 



Synallaxis brachyurus cailcae Chapman and 



Synallaxis brachyurus chapmani, subsp. nov. 



Type.— M.C. Z. 124,478. Adult cf. Colombia: Jiminez, 

 tropical zone of Pacific slope. 6 April, 1904. M. G. Palmer. 



Characters. — Most nearly hke S. h. nigrifumosa, but back less oliva- 

 ceous, more gra^,nsh, and under parts much paler and grayer. Chest- 

 nut of pileum and wings darker than in S. b. brachyurus and very much 

 darker than in S. b. caucae. Size large. Type, adult & ; wing, 66; 

 tail, 80; tarsus, 23; exposed culmen, 15. 



Chapman (Bull. Amer. mus. nat. hist., 1917, 36, p. 404) has already 

 called attention to this race from western Colombia, but has not 

 named it. We consider it quite as well marked as any of the other 

 subspecies. 



Dendrocincla lafresnayei christiani, subsp. nov. 



Type.— M. C. Z. 124,522. Adult 9. Colombia: near Pavas^ 

 Pacific slope of western Andes. 10 March, 1908. M. G. Palmer. 



Characters. — Similar to D. I. lafresnayei Ridgway of eastern Colom- 

 bia, and of about the same size, but much darker in color, and more 

 ohvaceous, less brownish throughout; darker and more oKvaceous 

 even than S. I. ridgwayi Oberholser of Panama and Costa. Rica.
