7 '2 Report of the President 



EXISTING INVERTEBRATES* 

 Henry Edward Crampton, Curator 



The past year has witnessed the resumption of full activity 

 in every one of the normal lines of the department's work. 

 In exhibition, increase and care of the study collections, in 

 research and publication, and in renewed field investigation, 

 the retrospect is most satisfactory, and reveals substantial 

 progress, both as regards the routine of the department and 

 also in the furtherance of the larger purposes which are held 

 steadily in view. 



The Bryozoa Group has engaged the chief energies of the 

 technical staff, and this is now completed, ready for reassembly 

 and installation in the Darwin Hall. This is a 

 Darwin Hall notable addition to the series of habitat groups, 

 with which it is in general harmony, although 

 it is unique in its display of minute animals as they appear 

 largely magnified. Besides the Bryozoa colonies which are the 

 central features, the marine plants and other organisms asso- 

 ciated with them are fully exhibited ; the models are numerous 

 and have required exceptional care and study for their con- 

 struction. Indeed, Mr. Miner's direction of the work has 

 been particularly engrossing, for it has involved the most care- 

 ful scientific study of the organisms as well as the devising of 

 novel methods in order that the result may be zoologically 

 accurate, permanent and pleasing. Several individual items 

 have been added to the Synoptic Series, among which the 

 peculiar Proterospongia may be mentioned. Other models 

 have been prepared for the Phylogeny Chart to be placed in 

 the Darwin Hall, and for a similar display in the Synoptic 

 Hall of Mammals. 



Additional museum cases have been remodeled, and this 

 task is now completed for half of the hall. Progress has been 



Under the Department of Invertebrate Zoology (see also pages 205 to 209).
