RESEARCH COLLECTIONS 77 



Still awaits being catalogued. There are about 10,000 specimens of 

 pelagic coelenterates and hydroids and probably 2000 other forms 

 (alcyonarians, stony corals, anthipatids, actinians). 

 The determined part of the collections contains: 



About 150 species of hydroids, chiefly West Indian, with about 30 



types. 

 About 450 species of pelagic coelenterates, from all parts of the world, 



with a few types. 

 About 100 species of stony corals, chiefly West Indian, with 35 types, 

 About 150 species of alcyonarians, from the West Indies and west coast 



of Central America, with about 30 types. 



The undetermined part of the collections contains about 700 trays 

 of stony corals, 50 trays of horny corals and a few actinians, anthi- 

 patids, medusae, millepores, etc., but the number of these unnamed 

 specimens has greatly diminished since Dr. Elisabeth Deichmann 

 became first Alexander Agassiz Fellow and then Curator and has 

 been caring for this material. 



The collections of pelagic coelenterates rank among the best in the 

 world. With regard to alcyonarians, stony corals and hydroids the 

 Museum has, through the Blake material, secured the most com- 

 plete series of species from the West Indian waters, and the Blake 

 material has been the foundation for several important monographs 

 from that region. There are also quite extensive collections from the 

 west coast of Central America and Brazil.
