28 ANNUAL REPORT OF THE 



REPORT ON THE COELENTERATES. 



By Henry B. Bigelow. 



The most important accession to the collection is a series of 

 hydroids from British Columbia, from Dr. C. McLean Fraser, 

 including many species not previously represented in the Museum. 

 Bermudan Medusae have been presented by Dr. W. J. Crozier, and 

 specimens from the Gulf of Mexico by Mr. Percy Viasco. 



My chief work has been the preparation of a report on the 

 Medusae and siphonophores collected by the U. S. Coast and 

 Geodetic steamer Bache during her cruise in the western Atlantic 

 in 1914, and the working up of the results of the Grampus cruise 

 of 1916. 



During the winter, in collaboration with the Interdepartmental 

 Board on International Ice observation and Patrol in the North 

 Atlantic, a program of oceanographic work was laid out for the 

 coast guard steamer Seneca, to be carried out during her ice survey 

 of the Grand Banks. But the outbreak of the war caused its 

 temporary abandonment.
