streak, so that when the tail is spread, there appears an irregular 

 white band near the end ; and in both sexes the white spots on the 

 quills are the same. 



In the Am. Ornith. the tail is much hollowed out in the middle, 

 appearing forked ; and the female has the quills marked with a white 

 spot, as in the male ; and this sex also has the spot on the chin, 

 clay-colour instead of white. It is known in Pennsylvania to most 

 persons by the name of Night Hawk.

LENGTH eight inches. Bill fifteen lines, black, furnished with 

 small bristles; general colour of the plumage blackish, spotted with 

 rufous and grey; on the fore part of the neck a sort of a half collar 

 of white ; the rest of the under parts not greatly differing from those 

 above. 



Inhabits Cayenne. — M. Bufibn's description is too concise to 

 discriminate the species; that author frequently referring to the PI. 

 enlnm. and which he means his reader should consult in addition. 

 We find, in the figure quoted, that the tail is two inches and a half 

 long, rather rounded at the end ; general colour dusky black brown, 

 crossed with three or four narrow, rufous, cream-coloured bars, mottled 

 with black, and the ends broadly tipped with the same ; greater 

 quills dusky black, marked with paler spots ; legs pale. 



This perhaps may be a distinct species, but seems somewhat allied 

 to the female of the White-throated, if not a young bird. 



M. d'Azara mentions one by the name of Nacunda, which word 

 signifies, in the language of the Guaranis, Wide-Mouth ; said to be 

 pretty numerous in Paraguay, but does not winter there. Inhabits
