:I922.] TRINIDAD BIRDS. 155 



In the second typ., th^ " han- " nest, the n^st is attached by 

 one side only to the underside of som-. overhanging leaf or fern frond 

 and practically always has the nest material prolonged beneath into 

 a long hanging tail-Hke attichment. Typical examples of thi5 are 

 seen ia Plate II and Plate III fig. 5. 



So far as can be ascertained from previous records and my own 

 -observations, the two types of nests are made by the following birds:— 

 Hans Nest. Saddle Nest. 



Brin Blanc White Breast. 



Rachette Common Emerald. 



Ballsier Ruby-Topaz. 



Carib Emerald. 

 ? Plastron. 

 ? Coquette. 

 No records are available of the other species, so there is still 

 plenty of opportunity awaiting anyone v/ho is sufficiently interested 

 to study the group for a few years. 



49. Phaethorni guyi guyi. Less. The Brine Bl nc. 

 Phoethornis guyi. Leotaud No. 63. 



This and the next species are comparatively dull coloured 

 humming-birds, usually found close to the ground in wooded 

 localities near water. Both are characterised by having the two 

 central tail feathers tipped with white and distinctly projecting 

 beyond the other tail feathers. This white projection is noticeable 

 even in flight. The present species is half again as big as the next. 



The back dull golden green ; an orange eyebrow and an orange 

 line beneath the eye ; between these two a dark line. The throat 

 reddish outlined with black. The rest of the body beneath grey, 

 tinged with reddish in the mi idle of the abdomen. Tail steel gr.en 

 to black, and edged with a narrow white border. The two centre 

 tail feathers 3 or 4 mm. longer than the rest and more than twice 

 as long as the outer pair. " The bill very long and slightly curved. 

 Total length about 1 70 mm. The female resembles the male. 



Nests of this species were found on two occasions in ths Maracas 



Valley. 



The first nest was found on June 7, 1920 attached to the end of a 

 leaf of an aroid creeper Philodendron sp. close to the edge of the 

 river. It was about nine feet above the level of the water. It 

 contained no eggs but the bird was constantly flying in its vicinity. 



The second nest was found on December 31. 1920 hanging from 

 a leaf of the same creeper over a bank of the river about three feet 

 above the normal water level. This last nest contained two eggs, 

 so presumably had been made within the pre^oxis few weeks.
