Woods Hole, Massachusetts, securing material and sketches 

 for a projected group which will exhibit the fauna and flora of 

 the Sound bottom. Mr. Miner is continuing the work on the 

 synonymy and bibliography of the American Myriapods. Dr. 

 Van Name has practically completed his monograph on the 

 West Indian Ascidians, which covers also the forms of related 

 territories such as southern United States and Bermuda; this 

 research is a valuable contribution to the work of the Museum, 

 in connection with the Biological Survey of Porto Rico in 

 cooperation with the New York Academy of Sciences. Pro- 

 fessor G. A. MacCallum is engaged in studying the parasites 

 collected by the Congo Expedition, and has already submitted 

 for publication a paper on "A Trematode Parasitic in Ele- 

 phants." A paper entitled "On the Anatomy of the Leech 

 {Ozobranchus branchiatus Menzies)," by W. G. and G. A. 

 MacCallum, is also in press and will appear shortly. Dr. Lutz 

 has collected a large amount of material with special reference 

 to the needs of exhibition work and has also made substantial 

 progress in the study of North American bees of the group 

 Apoidea. Mr. Mutchler has continued his able studies on the 

 Coleoptera of Florida and the West Indies. Mr. Watson has 

 devoted considerable time to the securing of illustrative ma-

 pleted during the year a large and important paper on African 

 Vespidse. As in former years, members of the New York En- 

 tomological Society and other entomologists, notably Mr. B. 

 Preston Clark, have continued their generous cooperation. 



Just prior to his death Curator Gratacap submitted an exten-

 cially valuable, as it is based on his long retrospect 

 of the history and development of his division. 



The work of Curator Gratacap during the year was restricted 

 almost exclusively to labeling the study series of shells, the 

 marine univalves and bivalves being entirely completed. The 

 fresh-water shells, though still requiring some revision, are 

 primarily classified and arranged. Some rare and beautiful
