MEDUSA OF THE PHILIPPINES* AND OF TORRES STRAITS. 



BT ALFRED GOLDSBOROUGH MAYER. 



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 medusse 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 another part 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 Fisheries, 

 the Smithsonian Institution, and Princeton University for the oppor- 

 tunities I have enjoyed. 



In September and October 1913 the writer was leader of the expedi- 

 tion sent by the Carnegie Institution of Washington to Torres Straits, 

 Australia, and spent five weeks on the Murray Islands, about 70 miles 

 south of the New Guinea coast and within 6 miles of the seaward edge 

 of the Great Barrier Reef of Queensland.
