J922.] TRINIDAD BIRDS. 163 



59. Chlorostilbon atala. Lesson, Carlb Emerald. 

 The separation of this species from the other two Emeralds has 

 been given above. 



The male is golden-green to grass-green above. Rump green. 

 Tail steely blue-black. Under parts golden-green. Breast, when 

 viewed from behind, distinctly bluish. Bill black, short and straight. 



The female is distinct from the male. Dull green above 

 Under parts brownish-grey fading to white behmd. The two 

 outermost tail feathers tipped with grey. 



I have not met with this species. It is not recorded by Leotaud 

 unless it is the species referred to by him as the " Saphir-Savan 

 Polytmus mellisugus), but his description is insufficient to settle the 

 point definitely. 



It is mentioned by Chapman and Hellmayr records specimens 

 at Laventille and Tacarigua. 



It is also found in Barbados, where it is known to build a small 

 cup nest saddled on a twig. 



60. Florisuga mellivora, Linn. Jacobin. 

 Topaza mellivora. Leotaud No. 72. 

 This is a comparatively large humming bird easily recognisable 

 by the conspicuous white markings on the tail. 



In the male the head, neck and chest are uniform dark metallic 

 blue. A narrow white collar on lower neck. Back, lower neck, 

 upper and under wing coverts, central tail feathers, and sides of 

 breast bronze green. Abdomen and under tail coverts white. Outer 

 tail feathers white edged with dark brown. Wing feathers purplish 

 ibrown. 



The female is bronze green above. Chin white. Throat and 

 chest bronze green with some white edges to the feather. Breast 

 abdomen and flanks white. Tail green, blackish before the tip and 

 tipped with white, which is most conspicuous on the outer feathers. 

 Bill straight. 



According to Leotaud this species is not common. I have seen 

 one specimen at the Usine Ste. Madeleine in 1 919, but have no records 

 of its habits or nesting. 



Hellmayr records it from Caparo, Valencia and Laventille.
