ADVERTISEMENT.
The scientific publications of the United States National Museum consist
of two series, the _Proceedings_ and the _Bulletins_.
The _Proceedings_, the first volume of which was issued in 1878, are
intended primarily as a medium for the publication of original, and
usually brief, papers based on the collections of the National Museum,
presenting newly-acquired facts in zoology, geology, and anthropology,
including descriptions of new forms of animals, and revisions of limited
groups. One or two volumes are issued annually and distributed to
libraries and scientific organizations. A limited number of copies of
each paper, in pamphlet form, is distributed to specialists and others
interested in the different subjects as soon as printed. The date of
publication is printed on each paper, and these dates are also recorded
in the tables of contents of the volume.
The _Bulletins_, the first of which was issued in 1875, consist of a
series of separate publications comprising chiefly monographs of large
zoological groups and other general systematic treatises (occasionally in
several volumes), faunal works, reports of expeditions, and catalogues of
type-specimens, special collections, etc. The majority of the volumes are
octavos, but a quarto size has been adopted in a few instances in which
large plates were regarded as indispensable.
Since 1902 a series of octavo volumes containing papers relating to the
botanical collections of the Museum, and known as the _Contributions from
the National Herbarium_, has been published as bulletins.
The present work forms No. 73 of the _Bulletin_ series.
