of a classified card catalogue would greatly increase their usefulness 

 and research value, especially to visiting scientists. This work is 

 well under way, but the collections are so large that it will take 

 several years to complete the task. Each specimen is checked for 

 errors in labeling, again checked against the records, and a more 

 complete label provided. Cards for a classified catalogue call atten- 

 tion to any features of special interest which might easily be over- 

 looked. During the year catalogue cards and new labels have been 

 provided for 3,130 physical geology specimens. 



Department of Zoology 



Research . . . 



The discontinuance of active field work necessitated by the war 

 has had the benefit of making possible the completion of various 

 studies in progress on the existing collections, and the residual staff 

 has continued research in some of the Museum's major fields of 

 scientific interest. 



In the Division of Anatomy, Miss H. Elizabeth Story has con- 

 tinued work on the comparative anatomy of the carnivorous mam- 

 mals, in relation to the monographic study of the giant panda. 

 Several papers bearing on this project have been completed, and 

 are in press or have appeared during the year. Dr. Harry Sicher, of 

 the Chicago College of Dental Surgery, has continued his studies 

 of the functional anatomy of the masticatory apparatus. 



Publications of the Department issued during the year by the 

 Museum Press are listed on page 66. 



In the Division of Mammals, the appearance of The Mammals of 

 Chile, by Dr. Wilfred H. Osgood, Curator Emeritus, marks the com- 

 pletion of a Museum project undertaken in 1922. Dr. Osgood has 

 continued work on his check-list of South American mammals and 

 on collections of mammals from Ecuador and Peru. 



In the Division of Birds, Mr. Boardman Conover continued his 

 studies of game birds, and published two papers. Dr. Oscar Neu- 

 mann, a volunteer, continued studies on exotic birds, and supplied 

 information in aid of the Check-List of Birds of the World. 



In the Division of Reptiles, Curator Clifford H. Pope was engaged 

 in the completion of his report on the amphibians and reptiles of the 

 Chicago region, and on further studies of Illinois reptiles. Chief
