Excerpt from Catalogue of Batrachians and Reptiles of Central America and Mexico This work (bulletin No. 32) is the forty-second of a series of papers intended to illustrate the collections of natural history and ethnology belonging to the United States, and constituting the National Museum, of which the Smithsonian Institution was placed in charge by the act of Congress of August 10, 1846. It has been prepared at the request of the Institution, and printed by authority of the honorable Secretary of the Interior. The publications of the National Museum consist of two series - the Bulletins, of which this is No. 32, in continuous series, and the Proceed ings, of which the ninth volume is now in press. The volumes of Proceedings are printed, signature by signature, each issue having its own date, and a small edition of each signature is dis tributed to libraries promptly after its publication. From time to time the publications of the Museum which have been issued separately are combined together and issued as volumes of the Miscellaneous Collections. These are struck off from the stereotype plates from which the first edition was printed, and in this form are distributed by the Smithsonian Institution to libraries and scientific societies throughout the world. Volume 13 of these collections includes Bulletins 1 to 10, inclusive; volume 19, volumes 1 and 2 of the Proceed ings; volume 22, volumes 3 and 4 of the Proceedings; and volume 23, Bulletins 11 to 15, inclusive.
