64 Report of the President 



well toward completion. The larger groups under construc- 

 tion have been advanced, the Tide Pool Group is at least half 

 completed, much has been done on the marine bryozoan 

 group, the elaborate Physalia model needs little further work, 

 and the Tahitian model is colored and lacks only the casing 

 and the shell types for the several valleys. As in past years 

 much work has been done for other departments, especially 

 that of Public Health, for which four elaborate models illus- 

 trating the life of the fly and one of a flea have been con- 

 structed. 



The study collections have been amplified and improved in 

 many ways. The ''Albatross" material of Dr. Townsend's 

 expedition has yielded about 100 identified echinoderms, and 

 about 50 identified annulates. Professor Treadwell has sent 

 other valuable annulate specimens, some of which are from 

 his own collection. By exchange we have secured from Pro- 

 fessor Fauvel a notable and named series of the annulates of 

 France. From the Durban Museum, Natal, South Africa, 

 Crustacea and valuable Onychophora have been obtained by 

 exchange. The jars of the entire collection have been gone 

 over and have been refilled when necessary. 



Mr. Miner has continued his studies on North American 



and West Indian myriapods, and has published in the Journal 



_ ■ a short article on the Wharf Pile Group. Profes- 



Researcn 



sor Crampton's investigations on Polynesian gas- 



teropods and their evolution have been advanced, and the 



first volume of some 500 quarto pages is soon to be published. 



The special acknowledgments of the department are due 



to C. T. Ramsden of Guantanamo, Cuba, for material assist- 



, ance rendered to Dr. Lutz and for numerous 

 Insects and , , A Al ,, 



„ . m specimens donated to the Museum. We are 



P also indebted to Carlos de la Torre, of the 



Havana Museum, for many courtesies extended to Dr. Lutz 

 and Mr. Leng, not the least of which was the privilege of 

 studying and copying the notable lists of Gundlach, whose 

 records are of primary importance to students of the West 

 Indian fauna. The results of the expedition to Cuba made 

 by Dr. Lutz and Mr. Leng amount to more than 10,000 speci- 

 mens, collected with full ecological data and with a view to
