34 ANNUAL REPORT OF THE 



REPORT ON THE COELENTERATES. 



By Henry B. Bigelow. 



The most important accessions received during the past year 

 are the duplicate series of Medusae, ctenophores, siphonophores, 

 and hydroids collected by the Grampus in 1913 and 1914, and 

 the duplicate set of Medusae collected by the U. S. Coast Survey 

 steamer Bache in the Gulf Stream, during the winter of 1914. 

 Australian Medusae have been presented by Dr. H. L. Clark and 

 Mr. J. Gabriel, and other specimens by Messrs. J. H. Blake and 

 W. J. Crozier. 



The collection now contains 303 species (about 10,000 specimens) 

 of pelagic coelenterates (medusae, siphonophores, and ctenophores), 

 and 159 species of hydroids. A catalogue of the stony corals 

 has been commenced. 



The H. A. Ward collection of corals from the Great Barrier 

 Reef of Australia was identified by Prof. L. E. Griffin. This 

 series contains seventy-four species and over 200 specimens. 



The winter was spent on the report on the plankton and ocean- 

 ography of the Grampus cruise of 1914; and in sorting and identi- 

 fying the Bache medusae. 



Since May 1 I have had charge of the scientific work of the 

 U. S. Fisheries Schooner Grampus, and while her main object 

 has been an investigation of the Herring, I accompanied her on 

 oceanographic cruises in the Gulf of Maine in May, June, and 

 September. During the summer fifty oceanographic and plankton 

 stations have been occupied, and the work is still in progress. 



The remainder of the summer was spent in sorting the Bache 

 siphonophores, and in a visit to Prince Edward Island to study 

 the oceanographic methods employed by Dr. Hjort in the Canadian 

 government survey of Canadian waters.
