 this department; among these were 20 new species of reptiles. 



The classification, labelling, cataloguing and arrangement of the col- 

 lection was continued during the year. 



Much research has been carried on during the year. Lists of the 

 amphibians and reptiles of Nevada, Idaho and the Peninsula of Lower 

 California, with notes on the specimens in our collection, have been 

 printed. A descriptive account of all of the reptiles of Western North 

 America has been completed, and preliminary descriptions of 16 new 

 species of lizards and snakes have been published. 



The snakes of the genus Diadophis were borrowed by Dr. Blanchard 

 of the University of Michigan, and a large collection of oriental sala- 

 manders was sent to Dr. Dunn of Smith College for study. A series of 

 our California racers was studied by A. I. Ortenburger of the Uni- 

 versity of Michigan.

Library 



Work in the Academy library has been kept up-to-date throughout the 

 year 1921 and considerable progress has been made toward the incorpo- 

 ration into the library of the miscellaneous material accumulated during 

 past years. The number of volumes acquired by purchase during the 

 year was much smaller than in 1920, due to the excessive prices now 

 being charged by the European dealers and the difficulty experienced in 

 securing books at any price from the continental dealers. Additions by 

 gift were much more numerous than during the previous year. Most 

 of these additions came through the gift of Dr. Barton Warren Ever- 

 mann, Director of the Museum, a gift constituting by far the most im- 

 portant single accession received by the library in recent years. This 

 donation numbered about 6,500 items of which nearly 1,000 were bound
