Two Bird-Lovers in Mexico #270790

Parts of certain chapters have already appeared in print in the New York Evening Post. To facilitate reference to the birds observed and to the mammals which we were able to identify on our trip, I have added as an Appendix an annotated list, with reference to pages of the book, thus supplement ing the Index. In the preparation of this Appendix I am greatly indebted to Mr. E. W. Nelson, of the Biological Survey at Washington, for the identification of specimens. 0. William beebe.
