Since the publication of the last complete list of the fossil birds of North America, which appeared in the fourth edition of the Check-. In addition, certain species have been added, such as Geococcyx conklingi, which, though from deposits possibly of recent age, are known only from bones, and therefore do not find a proper place in the list of modern birds. Also included are records of recent ages for species such as Spisactus willetti and Coragypsoccidentalis, which range from Pleistocene to Recent but are known only from skeletal remains.

It is usually a dubious procedure to assume that Pleistocene subgroups were the same as those living in the same region today, and such an assumption. 2 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL.99 that the specific name in wide-ranging species in which several sub-specific forms are now recognized is used in a comprehensive sense, and.
