I have not, so far, been able to identify this Swift quite 
satisfactorily, as there are no specimens of any of the 
South American species in the National Collection exactly 
like it. It appears to me, however, that it is the bird men¬ 
tioned by Azara and described later by Vieillot. 
[In October 1901 I met with two specimens of this bird, 
but know nothing more about it.— W. F '.]
