30 MUSEUM OF COMPARATIVE ZO-OLOGY. [Jan. 



presented a valuable collection of carboniferous fossils from 

 Missouri. 



A detailed list of the persons to whom the acknowledgment 

 of the obligation of the Museum is due, will be found at the 

 end of this Report. 



The total of species received amounts to 1,969, including 

 22,634 specimens. 



Diligent effort is now making to carry further the sys- 

 tematic arrangement of the collection, and to advance the work 

 of cataloguing and numbering the specimens, so that they will 

 be readily accessible, and can be freely used for purposes of 

 study and comparison. At the same time, the extension of 

 our system of exchanges, which has already given such assur- 

 ance of success, will remain a prominent aim in our labor.
