Trogonurus collaris (Vieill.). Three specimens, an immature 9 and 

 adult cf and $ , Perico and Charapi, September. 



Frequently noted in the subtropical forests between Tabaconas and the 

 Chinchipe Valley. 



Trochilidae. 



Thaumasius taczanowskii fractus subsp. nov. 



Four adult males, Huancabamba, August. 



Type from Huancabamba, northwestern Peru, adult cf, No. 80118 

 M. C. Z. Collected August 9, 1916, by G. K. Noble. 



Characters. Similar to true T. taczanowskii (Sclater) but upper parts 

 darker and purer green, less mixed with grayish and less coppery; bill 

 much shorter. 



80118 cf ad. 68. 39. 22. 



Remarks. We have made our comparison with skins of true T. tac- 

 zanowskii collected by O. T. Baron at Malea Cajabamba, 8000 feet altitude, 

 and Otusco, 4000 feet altitude, Peru, received in exchange, some years'ago 

 from the late Count Von Berlepsch. These agree almost exactly with the 

 measurements and description of the type series. 



By far the commonest hummingbird about Huancabamba was this 

 species. It was observed very often in the shrubbery along the roadsides. 



Patagona gigas peruviana Boucard. Three adults, two males and 

 a female, Huancabamba, August. 



Ocreatus cissiurus cissiurus Gould. One adult male, Perico, 

 September 9. 



Adelomyia melanogenys maculata Gould. One adult male, Taba- 

 conas, September 2. This specimen appears to belong to this form rather 

 than to chlorospila Gould of more southern Peru. Compared with skins 

 from Ecuador, our one specimen is paler below and if others should prove 

 to be the same, it represents a pale unnamed race. 



Psalidoprymna gouldi chlorura (Gould). One adult male, Taba- 

 conas, August 29. 



Conopophagidae. 



Conopophaga peruviana Des Murs. One adult female, Perico, 

 September 12. With but a single female we are not sure this identifica- 

 tion is correct, possibly our bird is the female of C. castaneiceps Scl.
