94 PASSERES. TROCIIILIDyE. 



to bring them on again, with the sum result. 

 In their tortuous and rapid evolutions, the light 

 from their ruby necks would now and then flash 

 in the sun with gem-like radiance; and as they 

 now and then hovered motionless, the broadly ex- 

 panded tail, whose outer feathers are crimson- 

 purple, but when intercepting the sun's rays trans-

 an hour, and then I was called away from the post 

 of observation. Both of the Humming-birds ap- 

 peared to be adult males. I have alluded to the
