j6 Report of the President 



Unusual success has been attained in the field of research, 

 both on the part of members of the departmental staff and 

 also by collaborators who have generously given 

 Research their time and energy to working up collections 



Publication belonging to the Museum. The Curator has 

 made substantial progress on the second volume 

 of the series dealing with evolution in the genus Partula. Mr. 

 Miner has continued his work on the bibliography and syn- 

 onymy of the myriapods and has also virtually completed a 

 paper on a fossil representative of the group. Dr. Lutz, with 

 the cooperation of Professor Cockerell, has completed a not- 

 able work on the taxonomy and distribution of the higher 

 bees of North America. Dr. Van Name has continued his 

 investigations on th^ ascidians of the West Indies. Mr. 

 Mutchler has cooperated with Dr. Lutz in compiling an ex- 

 tensive annotated list of the type specimens of insects, other 

 than Lepidoptera and ants, in the Museum collections. Mr. 

 Watson has made progress in his studies on Lepidoptera. The 

 record of completed researches, as given below, is most note- 

 worthy; the papers already published and now in press deal 

 mainly with the Congo Collections, and in some cases with 

 the material obtained by the Crocker Land Expedition, al- 

 though several others are listed. The accomplishment, as re- 

 gards papers published in the Bulletin for 19 19 or ready for
