REPORT 



To the Honorable the Legislature of the State of New-York : 



The Regents of the University, as trustees of the State Cabinet 

 of Natural History, respectfully submit this their 



TWENTIETH ANNUAL EEPOET : 



The Report of the Curator gives the details of the work clone 

 in the State Cabinet during the year 1866, and presents a general 

 view of its condition under the following heads : 



1. The Library. 



2. The Geological Collection. 



3. The Palffiontoloofical Collection. 



4. The Economic Collection, ores, building stones, marbles, etc. 



5. The Mineralogical Collection. 



6. The European-Palfeontological Collection. 



7. The Zoological Collection. ^. 



8. The Botanical Collection. 



9. Fossil and recent bones, skulls, etc. 



In respect to the Zoological Collection, the Curator has stated 

 the condition of the several departments, and indicated their lead- 

 ing deficiencies. Some portions of the Marine fauna have but few 

 representatives, and the collection of Fresh-water fishes also needs 

 to be increased. 



The cases provided for the exhibition of the Conchological col- 

 lection are inadequate to its proper arrangement and display, and 

 many specimens are left packed in drawers. This department has 

 been greatly augmented by donations from the Smithsonian Insti- 

 tution, one consignment of which Avas received and acknowledged 

 in 1865, and another in 1866; the former of which numbers 1068 

 species and 1680 specimens ; the latter, 702 species and 1206 speci- 

 mens. Catalogues of both of these donations acconvpany the 

 present report.
