 Adult female — Upper parts less lustrous than in the male, the 

 feathers margined more or less with rufous gray ; wings as in male ; 

 tail with the middle feather brilliant green, the rest cmnamon with 

 a purplish black band running from the outer feather obliquely 

 downward and inward to the tips of the fourth on each side, form- 

 ing a broadly shaped mark ; between the black band and the cinna- 

 mon there is a spot of bright green, most conspicuous in the feather 

 next the central ones and growing gradually indistinct toward 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 male. 



I have not been able to find descriptions of all the modern 

 genera of this family, but I think it would form a new genus. 

 All the males procured by me, four in number, had but eight tail 

 feathers, while all the females, three in 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 rather shorter, and the central ones considerably (.005) 

 shorter. The feathers composing the tail in the female are broader 

 than those of the male ; the third from the outside is the longest ; 

 the 1st, 2d, and central one as in the male; and the 4th shghtly 

 shorter than the 3d. 



Ghordeiles popetue. Very abundant during the summer months, 

 but migrate farther south in autumn. They began to arrive about 

 the first of May, and were numerous by the 10th. 



Ceryle alcyon. Abundant during the winter. I saw none 

 after the 1st of April. 



Tyrannus caudifasciatus. Called " fighter " by the inhabitants,
