Following the normal Macrochires come the Caprimulgide. Of 
these, in the living state, I have examined only Caprimulgus 
europeus and Podargus cuvieri. The disposition of the cubital 
coverts in these is certainly not at all like that seen in the Swifts ; 
but it closely follows the arrangement seen in the Picarian birds. 
In these at least two series of the feathers next above the Greater 
Coverts show proximal overlap. An examination of the specimens

ot Podargus, Batrachostomus, Agotheles, and Caprimulgus in the 
National Collection, as well as of specimens of the same family else- 
where, confirms this view. The soft and downy nature of the 
feathers prevents satisfactory observation upon any feathers above 
the two lower rows of median coverts; but I have satisfied myself 
in regard to the point in question. While Caprimulgus and its allies 
seem to agree in this particular with Podargus, Steatornis (so far as 
one can judge by the unsatisfactory data furnished by skins) presents 
yet another type, which seems to follow that of the true Cuckoos 
rather than that of Podargus or its allies. In all the remaining
