REPORT ON THE DEPARTMENT OF MESOZOIC INVERTEBRATE FOSSILS 

 IN THE U. S. NATIONAL MUSEUM. 1892. 



By C. A. White, Honorary Curator. 



During the past year, as in preceding years, the work of this divi- 

 sion has been done wholly by members of the U. S. Geological Survey; 

 and yet the usual routine, and much of the special work pertaining to 

 it, has been fully attended to. 



The fossil collections have continued to increase during the year, the 

 most important accession having been received from the U. S. Geolog- 

 ical Survey. This accession (No. 25725) embraces 10,566 specimens 

 and includes some of the most important paleontological material which 

 has been studied by members of the Survey. A large part of this 

 accession is now placed in the exhibition series, and more of it will be 

 similarly placed as soon as time for the work can be spared. 



The entries in the Museum catalogue for the year range from 21752 



to 22170.
