INTRODUCTION. 



In 1909 Dr. Hugh M. Smith, the then Acting United States Com- 

 missioner of Fisheries (now Commissioner), gave to the author for 

 study a part of the collection of medusae now under consideration in 

 this article, and the authorities of the Smithsonian Institution kindly 

 permitted the use of a table in the building in Washington while 

 engaged upon this work. In 1910 the remainder of the collection was 

 sent to Princeton University, where the author occupied a research 

 room in Guyot Hall. Thus the collection was studied under the most 

 advantageous conditions, and it is a pleasure to express my sense of 

 indebtedness to the authorities of the United States Bureau of Fish- 

 eries, the Smithsonian Institution, and Princeton University for the 

 opportunities I have enjoyed. 



Previous reports upon this collection were published by the Car- 

 negie Institution of Washington in Publications 109 and 212. 



Thirty-one Scyphomedusae were obtained by the Albatross in the 

 Philippines and adjacent regions, of which 10 were new to science, 

 the list of species being as follows:
