This 12th and last part of “Type specimens of birds in the American Museum of Natural History” includes taxa in the passerine families included in volume 15 of Peters' Check-list of birds of the world (Mayr and Greenway, 1962). The original description of each name has been consulted and the currently accepted name of the taxon has been listed with reference to recent publications. The coordinates and modern names of type localities are given when found and comments on taxonomic history are provided. In this part, 355 names are treated.

This part of the type list, as well as all previous parts, are searchable and available for download from the AMNH Library website ( http://digitallibrary.amnh.org/dspace/).
