LOct. 



• 52. Cypseloides niger. Black Swift. — Noted a few but failed to 

 secure any. 



53. Lampornis virginalis. — Common at all points Avhich I visited. At 

 Aguadilla, July 21, 1900,1 found a nest, to which I was attracted by the 

 angry demonstrations of the female bird. I first noticed her chase a 

 Myiarchits antillarum out of the tree. It was a large tree standing in a 

 corn field, but I failed to locate the nest by watching the bird. She 

 several times took a flight of about ten rods, returning immediately, but 

 would not go to the nest. It was finally found by close search. It was 

 on the end of a limb about ten feet from the ground, and contained two 

 young about half grown. It was well sheltered by large leaves growing 

 above, was cottony in appearance and not particularly handsome, resem- 

 bling some of the poorer nests of Trochilus colubris. March i, 1901, 

 I made the following note : " Heard a Lampornis virginalis sing a 'song,' 

 a sort of prolonged trill or twitter. It also utters sharp chips. When 

 hovering in front of a flower the motion of the wings seems sometimes 

 quite slow, almost within the power of vision, and it sometimes alights 

 on a twig to feed from a flower." Their habits are in general much 

 the same as those of other hummingbirds. 



54. Sporadinus maugaei. Fairly common though not abundant about 

 Mayaguez and Las Marias. Not seen near San Juan nor on Vieques 

 Island. 



{To be concluded.)
