Publications of the United States National Museum 



The scientific publications of the United States National Museum include two 

 series, Proceedings of the United 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 acquired facts 

 in the field of anthropology, biology, geology, history, and technology. Copies 

 of each publication are distributed to libraries and scientific organizations and 

 to specialists and others interested in the various subjects. 



The Proceedings, begun in 1878, are intended for the publication, in separate 

 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. Bulletins 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 295 of the Bulletin series.
