1922.] TRINIDAD BIRDS. 165 



64. Polytmus thaumantias chrysobronchus, Shaw. Pearl. 

 Polytmus viridis. Leotaud No. 67. 

 Hellmayr records this species from Caroni Swamp, but I have 

 not met with it myself.. 



The male is pale bronze green above, brighter and more 

 glittering in the throat and breast, which have a pearly lustre. Tail 

 feathers bluish with the tips and a portion of the outer web 

 green. Wing feathers brown. Vent and under tail coverts white. 



The female is similar but not so bright and the abdomen is for 

 the most part white. 



I know of no records of its habits or nest. 



65. Lophornis ornatus, Bodd. Coquette, Whiskerando, Huppe-col, 

 King or Queen. Leotaud No. 76. 



The smallest of the Trinidad humming birds is known by several 

 different local names although it is by no means common. 



It IS immediately distinguished from all the other Trinidad 

 humming birds by its small size and the presence of a light band 

 across the rump. The male has also the characteristic crest and 

 whiskers. 



In the male the back, upper tail coverts, and abdomen are 

 bronze green. Forehead, face and throat glittering green. A 

 crest on head pale chestnut. Tufts of feathers on side of face white 

 tipped with green. A line of white across the lower back. Tail deep 

 chestnut. Wing feathers brown. 



The female has no crest or tufts, and the under side is entirely 

 cinnamon. 



I saw one specimen of this species feeding at flowers of Inga sp. 

 in Maracas Valley on February 8, 1921 . 



Hellmayr records having shot eleven specimens at LaventiUe. 



In the British Museum of Natural History there is exhibited a 

 small deep cup nest covered with lichen externally, which is said to 

 belong to this species. 



Family CYPSELID^. SwiFTS. 

 66. Panyptilia cayennensis, Gmel. White-collared Swift. 



Cypselus cayenensis. Leotaud No. 37. 

 In the Bull. Dept. Agr. Trinidad and Tobago, VI, 1907, 127, there 

 is an account of a nest of this species. 



The nest is flask shaped, over twelve inches in length, five 

 inches in diameter at the larger or upper end, hanging with a circular 

 opening or entrance at the base. At the inside of the larger end and 

 close to the point of attachment to the branch is a small shelf or nest 

 in which the eggs are laid, the bird entering by the opening at the base."
