REPORT ON THE DEPARTMENT OF INVERTEBRATE FOSSILS (MESO- 

 CENOZOIC) IN THE U. S. NATIONAL MUSEUM, 1885. 



By Charles A. White, Honorary Curator. 



No detailed report upon the operations of this department lias been 

 received. The curator has stated verbally that a number of accessions 

 have been received during the first six months of this year, and that 

 some of them constitute new additions to the collection. Descriptions 

 of these have been published in the various bulletins of the United 

 States Geological Survey. The work of preparing the collections of the 

 Museum has been in progress, and the installation of types has been 

 commenced. 



Since the beginning of the year considerable space has been assigned 

 to this department in the gallery of the Smithsonian Institution, and 

 the work of preparing material for exhibition has steadily progressed. 

 The space in the southeast court of the Museum building is occupied 

 by specimens belonging to this department which have been turned 

 over by the Geological Survey to the Museum, and in this court the col- 

 lections are prepared for installation.
