Show 188 MR. J. G. GOODCHILO ON THE [Apr. 6, Following the normal Macrocbires come the Caprimulgidas. Of these, in the living state, I have examined only Caprimulgus europceus 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 Fig. 5 a. Fig. 5. Fig. 4. Hirundo. Cypselus. Trochilus. of Podargus, Batrachostomus, JEgotheles, and Caprimulgus in the National Collection, as well as of specimens of the same family elsewhere, 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.
