Many additions to the herbarium have been made within the 

 year, the most important being a collection of 486 specimens of 

 mosses donated by Dr. C. Hart Merriam; 81 specimens received 

 in exchange from the U. S. National Museum ; 100 plants from 

 the Alps presented by Mrs. Zelia Nuttall ; and two collections 

 presented by the Botanical Club. 



The Curator reports that the needed data for the proper 

 labeling of the plants collected by the Academy's Galapagos ex-

 valuable specimens. The total number of accessions to the 

 department within the year is 4859.

 specialists for identification and study. The most important 

 of these are the Orthoptera of the Galapagos expedition, sent
