new Bryozoa Group. Much information was obtained on the 

 life histories of the forms to be represented, which will form 

 the basis, not only for exhibition work, but for future research. 

 Many notes, water-color sketches and preliminary models were 

 made directly from life. Dr. Lutz spent considerable time 

 during the summer in northern New Jersey obtaining material 

 for exhibition purposes. He had three main objects in view: 

 (1) an exhibit of spider webs, (2) an exhibit of the burrows 

 of bees, solitary wasps and other insects, and (3) an exhibit 

 showing the number of species of insects to be found in a sub- 

 urban back yard. Approximately five hundred species were 

 found in a lot 75 x 200 ft. in a town within easy commuting 

 distance of New York City. 



The Curator has made substantial progress in the study of 

 the land snails belonging to the genus Partula, collected in the 

 islands of Moorea and Raiatea. The Curator 

 Research also has nearly completed two papers dealing 



Publication w ^ n biological problems in the case of the Ameri- 

 can silk worm moth, Philosamia cynthia. Mr. 

 Miner has continued work on "The Synonymy and Bibliog- 

 raphy of American Myriapods." Dr. Van Name's paper on the 

 West Indian Ascidians, which was practically completed last 

 year, has been held in reserve pending his comparison and ex- 

 amination of certain other collections. A paper by Professor 

 G. A. MacCallum, entitled "A New Species of Trematode 

 (Cladorchis gigas) Parasitic on Elephants," was published 

 early in the year as a part of the results of the Congo expedi- 

 tion. A paper by W. G. and G. A. MacCallum, entitled "On the 

 Anatomy of the Leech Ozobranchus branchiatus Menzies," 

 was also published in the Museum Bulletin. An excellent 

 paper by Professor C. Branch Wilson, entitled "Parasitic 

 Copepods of the Congo Collection," is now in press, which de- 

 scribes several new species of this interesting group. The 

 paper on the Congo Mollusks by Professor H. A. Pilsbry is 

 now ready for publication. Professor Pilsbry is also working 

 on the Congo Cirripedes. The Crustacea of the Congo Col- 

 lection will form the subject of several papers which will 

 appear in the near future, the Brachyura being worked up by
