MUSEUM OF COMPARATIVE ZOOLOGY. 29 



REPORT ON THE COELENTERATES. 



By Henry B. Bigelow. 



The most important accessions received during the year are 

 the duplicate set of Medusae, ctenophores, and siphonophores 

 collected by the Grampus in 1915; the duplicate set of Medusae 

 and ctenophores collected by the U. S. Revenue Cutter Seneca 

 in the region of the Grand Banks of Newfoundland in 1914; and 

 a series of Medusae and siphonophores obtained during the oceano- 

 graphic explorations of the Canadian Government in 1914 in the 

 Gulf of St. Laurence and off Nova Scotia, presented by Dr. A. G. 

 Huntsman. Medusae from Tobago Island, West Indies, have 

 been presented by Drs. A. G. Mayer and H. L. Clark. The 

 Museum is also indebted to Dr. J. P. McMurrich for Medusae 

 from Vancouver Island. 



The card catalogue of stony corals, has been continued; it 

 now includes 107 species, but the greater part of the collection 

 still remains to be worked over. 



I was absent from the Museum from October, 1915 until March, 

 1916. Since then, my principal w T ork has been the preparation of 

 the report on the oceanographic cruises of the Grampus in 1914 

 and 1915, and the preparation of a report on the Medusae and 

 siphonophores collected by the Bache in 1914.
