home of this colony, as they were seen entering and leaving the lower 

 end of the flue, which is some fifty feet from the foot of the overhanging 

 cliff, and absolutely inaccessible. How far this opening extends 

 upward into the rock, there was no means of ascertaining. It seemed 

 quite dark, and evidently does not continue to the surface above. 

 The birds generally flew high, but early in the morning they occasion- 

 ally came low enough for a shot. Seven specimens were secured, all 

 in good feather. A few were seen above Tecpam, at 8,000 ft. 



103. Chaetura vauxii (Townsend). 



At Mazatenango two pairs of this species were taken, on the igth 

 of March, from a flock of about fifty. A moult of body feathers was 

 in progress on all of them. The rectrices and remiges, however, show 

 no sign of renewal. Iris dark brown. 



104. Chastura gaumeri Lawrence. 



Two specimens of this swift were secured at Los Amates the last 

 of January. In the dense vegetation of that section it was possible 

 to obtain a swift only by bringing it down as it passed over a shallow 

 stream. Both of these specimens were in unabraded plumage. Iris 

 dark brown. 



Family TrochilitUe. 



105. Phasthornis longirostris (Lesson & Delattre). 



This species was seen only at Los Amates where it was not uncom- 

 mon in the forest. Only one specimen was secured. Iris dark brown ; 

 maxilla black ; mandible flesh color; feet pale. 



106. Phasthornis adolphi Gould. 



A single specimen was taken in the swamps near Puerto Barrios. 

 None were observed outside the tierra caliente. Iris dark brown; 

 maxilla and distal half of mandible black; basal half of mandible 

 yellow; feet pale. 



107. Campylopterus rufus Lesson. 



The only locality where this fine hummer was seen was near Pana- 

 jachel, on the north shore of Lake Atitlan, where three were secured. 

 They frequented a sunny portion of a coffee plantation. This was 

 early in April, when the coffee bushes were blooming, which probably
