 DEPARTMENT OF INVERTEBRATE ZOOLOGY 



Henry Edward Crampton, Curator 



In pursuance of the general aims of the field work in this 

 department, two expeditions were made during the year to 

 localities of significance for the study of distribution and 

 evolution. Dr. Lutz and Mr. Leng spent several weeks in 

 Cuba, thus extending the study of geographical distribution 

 to another large element of the West Indies. Mr. Miner and 

 H. Miiller devoted four weeks to the collection and study 

 of the marine forms of Passamaquoddy Bay and its vicinity. 

 Earlier in the summer, Mr. Miner and Mr. Shimotori revisited 

 Nahant to obtain additional data for use in constructing the 

 Tide Pool Group. 



Mr. Mutchler has been appointed a scientific assistant. 



The expedition to Passamaquoddy Bay secured about 



2,000 specimens of marine life, many of which were new to 



, our collections. It is a pleasure to acknowl-

of St. Andrews, N. B., supported by the Canadian Government. 

 The Wharf Pile Group was completed and placed on 

 exhibition in the Darwin Hall early in the year; this marks 

 the acme of museum demonstration in the case of inverte- 

 brate animals, and greatly strengthens the series of marine 

 ecological groups. Numerous items have been added to the 

 synoptic series on display, ten of which are protozoans and 

 four bryozoans; in addition a long series of poriferan types is
