Specimens were loaned to C. A. Weatherly, K. K. McKenzie,

Mollusks 
Accessions were received from 73 persons and institutions. 
In the Manual of Conchology the account of Orculinae, a sub¬ 
family of Pupillidae, has been prepared and partly published. 
In collaboration with Mr. Ferriss, the Special Curator has pre¬ 
pared a paper dealing with the distribution and anatomy of land- 
shells of central Arizona. 
Mr. Vanatta has been chiefly employed in identifying specimens 
for correspondents, in preparing new material, and in working over 
and selecting specimens from several general collections received. 
About 888 specimens have been loaned for study to twelve 
investigators in other institutions. 
Minerals 
Mr. Samuel G. Gordon has continued in charge of the collection 
in this department. During the past year his time was largely 
spent in crystallographic investigation of minerals secured on the 
Vaux-Academy Andean Expedition of 1921, and at Franklin, N. J. 
Mr. Gordon spent part of the summer of 1922, visiting the feld¬ 
spar, mica and corundum mines of southwestern North Carolina; 
and shorter trips were made during the fall to Franklin, N. J., and 
Branchville, and Middletown, in Connecticut. 
The most notable accession of the year was the collection of the 
late William H. Shaw, presented by his son, Charles K. Shaw. 
The collection is particularly rich in fine amethysts, garnets, beryls 
and felspars from Delaware County, although it is by no means 
limited to local minerals. 
Other accessions are noted in the report of the Curator of the 
William S. Vaux Collections. 
Archeology 
The Department of Archeology has continued under the care of 
Miss H. Newell Wardle. 
During the year 1922, donations amounting to 567 specimens 
were received, exclusive of Mr. Clarence B. Moore’s addition to 
his collections. Some of the objects received are extremely rare.
