Publications of the United States National Museum 



The scholarly publications of the United States National Museum include 

 two series, Proceedings of the Uiiited States National Museum and United 

 States National Museum Bulletin. 



In these series are published original articles and monographs dealing 

 with the collections and work of the Museum and setting forth newly ac- 

 quired facts in the fields of Anthropology, Biology, History, Geology, and 

 Technology. Copies of each publication are distributed to hbraries and scientific 

 organizations and to specialists and others interested in the different subjects. 



The Proceedings, begun in 1878, are intended for the publication in sepa- 

 rate form, of shorter papers. These are gathered in volumes, octavo in size, with 

 the publication date of each paper recorded in the table of contents of the 

 volume. 



In the Bulletin series, the first of which was issued in 1875, appear longer, 

 separate publications consisting of monographs (occasionally in several parts) 

 and volumes in which are collected works on related subjects. Btdletins are 

 either octavo or quarto in size, depending on the needs of the presentation. 

 Since 1902 papers relating to the botanical collections of the Museum have been 

 published in the Bulletin series under the heading Contributions from the 

 United States National Herbarium. 



This work forms number 222 of the Bulletin series.
