of the new roof of the Museum. New cases have now been ordered, 
which will enable us to rearrange the specimens during the coming 
year. Meanwhile work has been continued upon such parts of the 
collection as were accessible. 
Large accessions have been received from numerous correspondents 
of the Curator. A list of these gifts may be found in the accessions 
to the Museum. The largest single accession has been the collection 
of Hawaiian land snails purchased from Dr. John T. Gulick. This 
series served as the basis of that author’s important studies on evolution, 
as well as his systematic papers on the Hawaiian fauna. Mr. H. 
Bloomfield Moore has contributed largely to our series of small land 
mollusks of Georgia and Florida by gatherings of leaves and humus, 
from which large numbers of shells have been picked by Mr. Vanatta. 
The Special Curator has been occupied chiefly with the preparation 
of the Manual of Conchology, the monograph of the family 
Achatinidce being completed this year, and the collections of this group 
revised and relabelled. Studies of American and Japanese mollusks 
have also been continued. The months of October and November 
A 
were spent in Arizona and New Mexico, chiefly in the Grand Canyon 
of the Colorado, the Florida and Chiricahua Mountains, and large 
collections of the mollusca of these regions were obtained. 
Mr. E. G. Vanatta has continued his efficient work as Assistant in the 
department throughout the year. 
H. A. Pilsbry, 
Special Curator.
