 species — P . polychropterus or P. nigriventris.

Yzabal. (218.) This bird is not uncommon. It sits in 

 the thick underwood, and is more frequently heard than seen. 

 The cry it utters begins with a sharp note not unlike the crack 

 of a whip. This is followed by a rattling sound not unlike the 

 call of a landrail, from which, however, it differs in being con- 

 tinuous and not repeated.

Duefias. " This month (x\ugust) these Swifts may be seen 

 almost every day, but they usually fly high — far out of gun- 

 shot. Birds with the collar perfect appear about as numerous 

 as those in the plumage of the present specimen " (with the 

 collar defined behind, but hardly marked in front.) — 0. S.

" Dueiias, July 25th. On this day I observed a considerable 

 number of these Swifts flying over the open land near the house. 

 Those with the rufous collar proved on dissection to be males ; 

 those without, females. I therefore conclude that they belong to 

 the same species. ^^ — 0. S. 



The occurrence of this beautiful Swift in Guatemala is of 

 great interest. I have seen New-Grenadian specimens, but they 

 are scarce. M. Robin is said to have discovered it in Trinidad, 

 and his specimens, now in the Museum of the Jardin des Plantes, 

 form the types of Vieillot^s and Lesson^s descriptions. See 

 Pucheran in Rev. ct Mag. de Zool. 1853, pp. 443, 445.
