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 fields of Anthropology, Biology, 

 History, Geology, and Technology. Copies of each publication are distributed to libraries and scientific 

 organizations and to specialists and others interested in the different 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 Cont7-ioutions from the United States National Herbarium. 



This work forms number 224 of the Bulletin series.
