Educational Use of Darwin Hall 73 



made on the next habitat group which will show the Crustacea 

 and associates of a selected area of the bottom of Vineyard 

 Sound, off Gay Head, Massachusetts. Plans are under way 

 for a Rotifer Group, which will be a companion in principle 

 and in location to the Bryozoa Group, and plans are also 

 progressing for a California Shore Group, centering about the 

 Echinoderms of Monterey Bay. The educational value of the 

 Darwin Hall has been greater than ever, for during the year, 

 11,454 pupils, belonging to 403 classes from 218 institutions, 

 studied the exhibits under the tutelage of their instructors. 

 Of the institutions represented, 75 are out of town, 157 are 

 public schools, 41 private schools, 12 parochial schools, and 

 8 are colleges. An extension of the educational work con- 

 sists of a series of beautifully colored illustrations showing 

 many of the notable exhibits, which were prepared under Mr. 

 Miner's direction for publication in the New York Tribune. 



The work of arranging and cataloguing the general inver- 

 tebrates has been completed by Dr. Van Name, and the col- 

 lections are now in final condition. Current 

 General accessions have been incorporated in the gen- 



Collections era ^ sei "i es > with an ease that proves the correct- 

 ness and practicability of the department's sys- 

 tem. Mr. Frank J. Myers has given largely of his time and 

 energies to the group of Rotifera, which he has recatalogued 

 and remounted when desirable, bringing the nomenclature to 

 date in all cases ; furthermore, he has generously added to 

 the collection so that it is becoming one of the most complete 

 series in existence. An important addition is a series of iden- 

 tified annulates from the West Indies, received from Pro- 

 fessor Aaron L. Treadwell. Mr. Arthur Jacot has devoted 

 his energies to the cataloguing and rearrangement of the ma- 

 rine gastropods. This work has involved to date the -writing 

 of 13,900 departmental catalogue cards and 9,600 reference 

 cards.
