Report of the President 41 



Work has progressed on a reference catalogue of the 

 collection of amphibia and reptiles which is to be moved into 

 a well-equipped fifth floor room for greater convenience in the 

 work. Negotiations are pending for important exchanges with 

 scientific institutions. Much valuable material has been 

 acquired and catalogued through the generosity of the Cleve- 

 land H. Dodge Fund and through other gifts, especially those 

 from the New York Zoological Park and the New York 

 Aquarium. 



LIVING INVERTEBRATES— DARWIN HALL 



Henry Edward Crampton, Curator 



Department of Invertebrate Zoology. — Substantial 

 progress has been made in all the varied lines of activity in 

 which the department is engaged. The several exhibition

 members of the staff have been continued with success. 

 Through its recent reorganization the department is now com-

 immediate supervision of Mr. Miner, is concerned with the 

 general invertebrate collections, the Darwin Hall and the

 exhibition Hall of Molluscs. The entomological collections as 

 a whole, together with the Hall of Insect Life and of Local 

 Insects, are under the general charge of Dr. Lutz, whose 

 staff of assistants has been materially strengthened by the 

 addition of Mr. Grossbeck, appointed August 1, 1910. Mr. 

 Beutenmuller is in immediate charge of the Lepidoptera. 



For the furtherance of his service to the Museum, and also 

 in connection with his own research, during the past summer 

 Curator Crampton visited numerous museums and zoological 

 institutions in England, France, Belgium, Holland, Germany, 

 Austria and Italy. Especially profitable was an additional 

 visit to the Oceanographic Museum at Monaco. The present
