BIRD LIFE IN THE URUBAMBA VALLEY OF PERU. 65 



Family MICROPODIDAE. 



SWIFTS. 



(968) STREPTOPROCNE ZONARIS ZONARIS (Shaw). 



Hirundo zonaris Shaw, in Mill. Cim. Phys., 1796, p. 100, pi. 55 (no type locality, 

 Chapada, Matte Grosso, Brazil, proposed as type locality; see Chapman, Bull. 

 Amer. Mus. Nat. Hist., vol. 33, 1914, p. 604). 



Chaetura zonaris Berlepsch and Stolzmann, Ornis, 1906, p. 96 (Santa Ana). 



Two specimens from the Tropical Zone agree in size with Matto 

 Grosso specimens and in color anci size with a specimen from near 

 Rio." The latter was collected in 1916, while the Chapada birds, 

 collected in 1883-1885, have evidently faded materially and are 

 therefore browner in tone than freshly collected specimens. 



Compared with the type of altissima, the two Peruvian birds have 

 a narrower breast-band, less evident whitish margins on the bend of 

 the wing, a darker forehead, and a bluer tone of color and are slightly 

 smaller in size. 



Lower Urubamba Canyon, altitude, 4,000 feet, 1 male, 1 female. 



(983) CYPSELOroES BRUNNEITORQUES BRUNNEITORQUES (Lafresnaye). 



Chaetura brunneitorques Lafresnaye, Rev. Zool., 1844, p. 81 (Colombia). 

 Cypseloides brunneitorques Berlepsch and Stolzmann, Ornis, 1906, p. 96 (Idma). 



Our two specimens are from the Subtropical Zone. They agree 

 with Colombian birds. The female has a broad rufous collar not so 

 clear in color as in a Colombian male. 



Torontoy, 1 male, 1 female. 



(989a) MICROPUS PARVULUS Berlepsch and Stolzmann. 



M. andecolus parvulus Berlepsch and Stolzmann, Proc. Zool. Soc, 1892, p. 384, 



prov. descr. footnote (lea, Peru). 

 Micropus peruvianus Chapman, Proc. Biol. Soc. Wash., vol. 32, 1919, p. 253, 



fig. 2. (OUantaytambo, Peru.) 



Specific cliaracters. — Resembling Micropus andecolus (Lafresnaye 

 and d'Orbigny), but tail shorter, less deeply forked, white areas of 

 the plumage without buffy tints, forehead darker, basal imder tail 

 coverts with much less white. Tailed forked for 13.5 mm. 



Common in the Temperate Zone and ranging downward to the 

 upper limits of the Subtropical Zone. Doctor Hellmayr calls my 

 attention to a provisional description of this form, as quoted above. 



OUantaytambo, 2; Huaracondo Canyon, 2; Torontoy, 2. 



(991) MICROPUS MONTIVAGUS (d'Orbigny). 



Cypselus Tnontivagus d'ORBioNY, Voy. Amer. Mer., 1835-1844, p. 357, pi. 42, fig. 

 1 (Samaypata, Bolivia). 



Compared with a female from the Province of Santa Cruz, Bolivia, 

 this Peruvian bird is blacker and has no white in the tail. 

 Torontoy, 1 female.
