n and
Doctor Robert M. Mengel for their kind help, and Doctor Harrison B.
Tordoff for first suggesting this study to me. Unless otherwise stated,
the nomenclature in this paper is that of the A.O.U. Check-list
Committee (1957). Catalogue numbers are those of the Museum of Natural
History at the University of Kansas. In so far as known to me, all
birds recorded in the literature from Coahuila are listed below. In a
few instances the only support for occurrence is the ascription of a
given kind to Coahuila (without mention of date, catalogue number, or
precise locality) by Friedmann, Griscom, and Moore (1950), and/or the
A.O.U. Check-list Committee (1957); when this is so the entire entry is
inclosed within brackets. In the accounts beyond, an asterisk indicates
that the kind breeds in Coahuila; two asterisks indicate probable
breeding in the State.
