Educational Use of Darwin Hall 63 



LOWER INVERTEBRATES* 



Henry E. Crampton, Honorary Curator 

 Roy Waldo Miner, Associate Curator in Charge 



At the beginning of the year, the Department of Inverte- 

 brate Zoology was divided into two departments, the De- 

 Reorganiza- partment of Lower Invertebrates and the De- 

 tionand partment of Entomology. This change was a 



Changes in logical one, due to the growth of the original 

 * taff department and to the natural cleavage between 



the subject matter and technique of the insects on the one 

 hand and the lower invertebrates on the other. The former 

 Curator, Professor Henry E. Crampton, was made Honorary 

 Curator of Lower Invertebrates, with Roy W. Miner as 

 Associate Curator in Charge, while Doctor Frank E. Lutz 

 was promoted to the Curatorship of Entomology. Dr. Wil- 

 lard G. Van Name was promoted from the grade of Assistant 

 to that of Assistant Curator. Professor A. L. Treadwell was 

 retained as Research Associate in Annulata and Mr. Frank 

 J. Myers as Research Associate in Rotifera. 



There has been noteworthy progress in exhibition during 

 the year. The work naturally falls under two main head- 

 ings: The Darwin Hall and the Hall of Mollusks. 



Most of the items for the Gay Head Sound-Bottom Group 

 have been completed in the modeling room, and the group 

 is now in the Darwin Hall for assemblage and 

 tt „ installation. The work has involved the con- 



struction of many parts in glass, celluloid and 

 wax to represent the algae and invertebrate life at the bottom 

 of Vineyard Sound, Massachusetts, centering about the Crus- 

 tacea. In the case of the latter, original specimens have been 

 carefully articulated, mounted and colored from life. The 

 glass modeling, as usual, is due to the excellent skill of Mr. 

 Herman O. Mueller, while the modeling in plaster, wax and 

 celluloid is that of Mr. Chris E. Olsen. Mr. W. H. South- 

 wick has nearly completed the coloring of the transparent 

 backgrounds, with very creditable results.
