BULLETIN 125, UNITED STATES NATIONAL MUSEUM. 
Our hearty thanks are due to Dr. F. C. Clark, of Los Angeles, California, and 
Dr. Ralph Arnold, of Pasadena, California, who have supplied us with practically 
all of the faunas described from the Pleistocene of California. 
The methods of study of the bryozoa and various other subjects relating to 
them in general have been described in our Early Tertiary volume, to which the 
reader is referred. We have, however, added to the present volume a bibliography 
of bryozoan literature published since 1899, the list of literature up to this date 
being contained in the work by Nickles and Bassler of 1900. 2 
Although the present work deals primarily with North American Post-Oligocene 
fossil Bryozoa, the descriptions of a few small faunas from the Oligocene rocks 
of the West Indies and of several miscellaneous Eocene species are added for 
various reasons.
