Subgenus II. Podochtefes, tarsis omuino vestitis 8. leucopygus. 



I have a few remarks to offer on these species. 



Subgenus 1. Chordeiles. 



1. Chordeiles virginianus. 



Chordeiles virginianus, auctt. plur. 



C. popetue, Baird, B. of N. A. p. 151. 



Hab. Atlantic States of North America, southwards through Cen- 

 tral and South America into Brazil. 



I cannot agree with my friend Prof. Baird in rejecting the old and 

 generally adopted name of virginianus for this species, although it is 

 no doubt true that Gmelin's Caprimulgus virginianus is only in part 

 applicable to it. 



Tbis Night-Hawk seems to be widely distributed in America. If 

 extends from the Atlantic northern states, throughout Mexico and 

 Central America, to Panama, whence Mr. M'Cleannan has forwarded 

 specimens. Natterer collected examples in the interior of Brazil 

 (his species no. 93) which I cannot separate from the northern bird. 

 My two specimens, obtained by that naturalist at Araguay in Octo- 

 ber 1823, are of the dark-coloured variety with little rufous on the 

 back, as in most examples from the northern Atlantic states. 



2. Chordeiles henryi. 



Chordeiles henryi, Cassin ; Baird, /. c. p. 153. 



Similis C. virginiano, sed alis extus albo pariegatis, et ventre imo 

 crissoque purius albis. 



Hab. New Mexico and Northern Mexico. 



This seems to me little more than a pale variety of C. virginianus, 

 as already suggested by Prof. Baird. Mr. Dresser obtained it at 

 Matamoras, as mentioned in the ' Ibis,' 1865, p. 47, along with C. 

 virginianus. 



I shall leave it, however, to Prof. Baird, who has much better op- 

 portunities than myself for forming an opinion, to say whether this 

 form is to continue to rank as a species or not. 



3. Chordeiles minor. 



Chordeiles minor, Cab. J. f. Orn. 1856, p. 5 ; Sclater, Cat. 

 p. 2/9. 



Similis C. virginiano, sed minor : long, tola 7'7, alee 7, caudce 4. 

 Hab. Cuba (Gundl.) ; Jamaica (Osburn).
