 I arrived at Altagracia the first of November, but no specimens of 

 this swift were observed until the 2nd of February following"; after that 

 date they were seen but owing to their habit of flying high up, speci- 

 mens were secured with the greatest difficulty. Noted as not uncommon 

 at Caicara during March and April.

 Berlepsch and Hartert's paper includes seventeen species, fifteen
