It will be noted that 8 of the species reported, including 

 all the new forms, belong to the suborder Rhizostomse. This 

 essentially tropical suborder seems to include the greater part 

 of the Philippine forms as 16 of the 29 species and varieties 

 reported from the Islands belong to that group. There are 

 undoubtedly many medusae new to science and others as yet 

 unreported from the Philippines to be found in the waters of 

 the Archipelago. While on launch trips, during May and June, 

 1913, along the coast of Palawan and the islands between Pala- 

 wan and Culion, I saw many medusa? not found in this collection. 

 Most of them were Rhizostomse, but at least three species of 

 Pelagidae were common. Large Beroe-like ctenophores were also 

 very numerous, but attempts to preserve them were unsuccessful. 



While I have attempted to give a fairly complete description 

 of new species and a sufficiently complete description of old 

 species for diagnostic purposes, I have not attempted detailed 

 anatomical discussions. In the diagnosis of old species, and 

 in matters of general classification, I have followed very closely 

 Mayer's monumental work, The Medusae of the World. Full 

 synonymies of previously described species will be found in 

 that work. 



Mayer describes 20 species and varieties of Scyphomedusaa 

 which have been reported from the Philippines. The fact that 

 all but one of these were reported for the first time from the 

 Albatross collection made during the years 1908 to 1910 shows 

 how little attention has been paid to the collecting of Scyphome- 

 dusae in Philippine waters. The present paper adds 9 species and 

 varieties, making a total of 29 species and varieties of Scyphome- 

 dusae from the Philippines. A list of these, with localities when 

 known, follows. 



1. Carybdea rastonii Haacke, Luzon and Mindoro [Mayer, 1910].
