“ The species are numerous in the tropical latitudes of both hemispheres. Two are found in North America, which, in their external characters, approach so near to the genuine Cuckows, that they barely come within the definition of the present group.It frequently happens that species, originally well described, become involved in obscurity by compilers. Le Vaillant, who first described this bird, supposed it a variety of his Coucou Edolio: but in this he was mistaken; the one being a Cuculus; the other a Coccyzus. We should have thought our species might be the Cuculus Afer. ”
