BIRD LIFE IN THE URUBAMBA VALLEY OF PERU. 83 



(2318) SYNALLAXIS HYPOSPODIA Sclater? 



Synallans hypospadia Sclater, Proc. Zool. Soc, 1874, p. 10 (Bahia).— Behlepsch 

 and Stolzmann, Ornis, 1906, p. 92 (Santa Ana). . 



A single specimen agrees with one from Bahia, but the identification 

 must be considered as provisional.^ 

 Santa Ana, 1 . 



(2373) SIPTORNIS ALBICAPILLA (Cabanls).« 



Synallaods albicapilla Oabanis, Journ. fur Ornith., 1873, p. 319 (Maraynioc, 

 Peru). 



A male agrees with Cabanis's description. 

 Cedrobamba, 1 male. 



(2378a) SIPTORNIS MODESTA PROXIMA, new subspecies. 



Suhspecific characters. — Similar to Siptornis modesta sajamae 

 Berlepsch, but upper parts darker, Saccardo's umber rather than 

 buffy brown; band in wing darker; hazel instead of cinnamon- 

 rufous; tail shorter. 



Type, — Cat. No. 145,191, Amer. Mus. Nat. Hist., female adult, 

 Ttica-Ttica, 11,500 feet, near Cuzco, Peru, July 2, 1916; F. M. Chap- 

 man. 



Specimens examined. — Siptornis modesta proxima. Peru: Type- 

 locahty, 1 female (July 2); La Raya, 14,000 feet, 3 males, 1 female 

 (April 5); Junin, 12,900 feet, 1 male (April 3). Siptornis modesta 

 sajamae. Peru: Puno, 12,600 feet, 1 male, 1 female (Aug. 6, 2); 

 Tirapata, 12,700 feet, 5 males, 8 females 1 ? (July 28-Aug. 3). 



Remarhs. — It is difficult to understand how so coimnon, easily ob- 

 served, and widely distributed a species as Siptornis modesta appears 

 to be, at least in southern Peru, can have escaped previous observers. 

 Possibly it has been recorded under some other name, but, if so, I 

 have failed to find one that is appUcable to it. It belongs in that 

 section of the group having the rump and upper tail coverts uniform 

 with the unstreaked back and all the retrices, including the outer 

 pair, bicolored, and this excludes the possibility of its being referable 

 t© S. pudihunda, as that species is commonlj'' described. 



Mr. Charles Chubb has been kind enough to confirm my identi- 

 fication of Tirapata specimens as Siptornis modesta. They agree in 

 color ^vdth examples from Puno which are doubtless referable to 

 Siptornis modesta sajamae Berlepsch, of western Bolivia, but are 

 nearer the form here described in size. Specimens from just beyond 

 the divide at La Raya, might be expected to resemble those of 

 Tirapata, distant only some 60 miles, and where apparently similar 

 environmental conditions prevail; but, on the contrary, they agree
