" Adult female : — Upper parts less lustrous than in the male, the feathers margined more or less with 

 rufous grey ; wings as in the male ; tail with the middle feathers brilliant green, the rest cinnamon, with a 

 purplish-black band running from the outer feather obliquely downward and inward to the tips of the fourth 

 on each side, forming a broadly-shaped mark ; between the black band and the cinnamon there is a spot of 

 bright green, most conspicuous in the feather next the central ones, and growing gradually indistinct towards 

 the outer ones; throat pale rufous white, the centre of the feathers darkest, and on the sides and posteriorly 

 a little green ; abdomen entirely rufous ; legs and crissum pale rufous. The dimensions do not differ from 

 those of the male. 



" Young male in winter : — Upper parts intermediate in brightness between the male and female ; throat 

 white, with a few feathers beginning to show the violet ; tail as in the male. 



" All the males procured by me, four in number, had but eight tail-feathers ; while all the females, three 

 m number, had ten. It can hardly be supposed that in four specimens, the same two feathers, and but two, 

 should have been lost from every specimen. In form the tail-feathers are rather narrow, and the inner 

 webs of the two outer slightly falciform or emarginated. The two outer feathers are slightly shorter than 

 the next, which are the longest ; the next two again are rather shorter, and the central ones considerably 

 shorter. The feathers composing the tail of the female are broader than those of the male ; the third 

 from the outside is the longest; the first, second, and central one as in the male : and the fourth slightly 

 shorter than the third." 



Dr. Bryant has deceived himself as to the number of the tail-feathers in the male : all Humming-Birds 

 have ten ; but in some instances the middle feathers are so short as to be entirely hidden by the coverts, and 

 this is precisely the case in the male of Calothorax EvelyncB.
