458 Bangs and Noble, Birds of Peru. [oct. 



Vireosylva josephse josephse (Scl.). Two adult males, Tabaconas, 

 August. 



Cyclarhis virenticeps Scl. One adult female, Tabaconas, September 

 4. 



This bird was shot in a heavily wooded region, strongly Ecuadorean in 

 its fauna (especially shown by the reptiles and amphibians), one of the 

 very few really forested areas through which the expedition passed. 



Cyclarhis coutrerasi Tacz. Three specimens, one immature and two 

 adi^t females, Perico and Huancabamba, August and September. 



All three were taken in open, sandy country. 



The immature bird has the crown mixed ferruginous and green and gray, 

 a ferruginous band surrounding the occiput and passing through the eye 

 on each side to the front, which is also ferruginous. 



Both adults are extreme of this form; the bird from Tabaconas is an 

 extreme of C. virenticeps and we are therefore forced to regard these two 

 forms as distinct species. 



Hirundinidse. 



Stelgidopteryx ruficollis uropygialis (Lawr.). One adult male, 

 Bellavista, September 24. 



Pygochelidon cyanoleuca (Vieill.). Six specimens, three immature, 

 three adult, both sexes, Huancabamba, Perico and Charapi, August and 

 September. 



The adults have completed or nearly completed the postnuptual moult, 

 and are greenish steel blue above. In examining a large series from Costa 

 Rica we find autumnal specimens constantly more greenish, steel blue less 

 violaceous than spring killed examples. Peruvian birds agree exactly, so 

 far as we can see, with the Costa Rican ones. On the other hand all skins 

 from eastern Brazil to the Santa Marta region of Colombia, regardless of 

 seasonal differences, are much more truly violaceous above, and while the 

 difference is slight it appears to be constant and it may still be found 

 expedient to use the name P. cyanoleuca montana (Baird) for the northern 

 and western form. 



Mniotiltidse. 



Myioborus verticalis verticalis (d'Orb. & Lafr.). Six adults, both 

 sexes, Tabaconas and Huancabamba, August. 



Coerebidse. 



Diglossopis cserulescens pallida Berl. & Stolzm. One adult (sex not 

 determined), Tabaconas, September 3." 



This example is wholly referable to the southern form, agreeing per- 

 fectly with a skin collected by O. T. Baron at Leimabumba, which had 

 been determined by the late Count Von Berlepsch.
