jira Peninsula, reaching, however, Loma Larga and Fonseca, in the 

 valley of the Rio Rancheria. It is perhaps most abundant around 

 Fundacion and Tucurinca, but there are several records for other lo- 

 calities to the northward. A nest was found beside the road between 

 Mamatoco and La Tigrera on June 12, 1 91 9. It was a flimsy affair, 

 composed of twigs, vegetable fibers, and a few feathers, and placed 

 in a small cavity excavated in the face of a nearly vertical bank. It 

 contained four white eggs upon the point of hatching. 



405. Progne chalybea chalybea (Gmelin). 

 Three specimens: Mamatoco and Fundacion. 



A considerable flock of these birds lives in the town of Santa Marta, 

 breeding around the housetops, where they can not be shot. At Fun- 

 dacion a single one was seen and secured; and two more at Mamatoco, 

 out of a half-dozen seen. It proved to be fairly cornmon along the 

 liver at Fonseca in July, 1920, and was noted also at Arroya de Are- 

 nas. The species has an extensive distribution in tropical America, 

 and it is odd that it is not commoner in this particular region.

 specimens are of course referable to the form occidentalis, described 

 from " Bogota." The present series includes several immature male 

 birds, in a peculiar plumage, variously intermediate between that of
