Fam, CypselidjE. 

 Four Swifts were obtained by Mr. Bartlett in Upper Amazonia — 

 one true Cypselus and three Spine-tails (Chcetura). Of these one 

 Chcetura only can be considered a characteristic Upper-Amazonian 

 form, the others being more or less widely distributed.

 " I met with this little Swift in the towns of Xeberos and Chami- 

 curos in small flocks." — E. B. 



2. Chjetura zonaris (Shaw); Scl. & Salv. P. Z. S. 1867, p. 752.

" Xeberos and Chamicuros. Met with in flocks about the towns."

4. Chcetura sclateri, Pelz. Orn. Bras. p. 56. 



" I obtained only two specimens of this rare species at Chamicuros. 

 It was found in company with Ch. poUum.' 1 — E. B. 



I identify this Swift from v. Pelzeln's description. Natterer dis- 

 covered it at Borba. I have recently obtained a second specimen 

 from Ecuador (probably from the Rio Napo), which agrees with 

 Mr. Bartlett's skin.— P. L. S. 



Fam. CaprimulgidjE.

 tibius longicaudatus, Chordeiles rupestris, and Hydropsalis trifur- 

 cata are peculiar Amazonian species.
