1922.] TRINIDAD BIRDS. 161 



Back dark bronze-green. Head and breast emerald. Rump 

 coppery-bronze. Tai: very dark bluish-purple. Breast feathers, 

 when viewed from in front, emerald, when viewed from beneath, 

 brown. Under tail coverts coppery-bronze. 



A nest of this species, containing two almost fully fledged young 

 was found on January 29, 1921, in the fork of a bamboo overhanging 

 the river in Maracas Valley and about seven feet above the surface 

 of the water. 



The nest (PI. Ill, fig. 6) is deep cup shaped, about 1| inches 

 across and about the same depth in outside measurement, and about 

 I inch across and 1 inch deep inside. It is saddled in the fork of 

 a twig. 



The nest is made of brown dead moss-like material {}Selaginella) 

 It is covered on the outside with small pieces of grey-green lichen and 

 green moss, lightly covered with spiders web, particularly towards the 

 base. The inside is lined with dried scale leaves of young ferns and 

 dark brown hairy seeds. 



The stomach of the adult bird feeding the young in the nest 

 mentioned above, on January 29, contained the remains of several 

 small ies of the genera Diloplous and Scatopsa (Diptera. Scatopsidae).

 This and the next species are distinctly larger hummmg birds 

 than the emeralds, with a larger slightly curved bill. 



The present species is, in the male, dark green above, middle 

 tail feathers purple with dark edging, throat and sides of abdomen 

 dark rich green, abdomen and under tail coverts and under-wing

The female differs from the male in being white on under surface 

 with a broad black line slightly edged with dark green on the throat 

 and middle of abdomen, also white tips to outer tail feathers. Bill 

 rather long and slightly curved. 



I have not met with this species and found no record of its nesting.
