The present series, entitled "Smithsonian Miscellaneous Collections," is intended to embrace all the octavo publications of the Institution, except the Annual Report. Its scope is not limited, and the volumes thus far issued relate to nearly every branch of science. Among these various subjects zoölogy, bibliography, mineralogy, and anthropology have predominated.
The Institution also publishes a quarto series entitled "Smithsonian Contributions to Knowledge." It consists of memoirs based on extended original investigations, which have resulted in important additions to knowledge.
CHARLES D. WALCOTT, Secretary of the Smithsonian Institution.

This work is in the public domain in the United States because it was published before January 1, 1929.
The longest-living author of this work died in 1927, so this work is in the public domain in countries and areas where the copyright term is the author's life plus 96 years or less. This work may be in the public domain in countries and areas with longer native copyright terms that apply the rule of the shorter term to foreign works.
