This paper has for its purpose the publication of miscellaneous 
new data concerning the scyphomedusan fauna of the Philippine 
Islands and includes the descriptions of two new genera and one 
new species. Since my former paper on Philippine Scyphome- 
dusse (1914.), Mayer has published (1915): an article on the 
“Medusae of the Philippines and Torres Straits.” The Philip- 
pine material for that paper, as well as that for his descriptions 
of Philippine forms in “Medusae of the World” (1910), came 
from the collections in Philippine waters of the United States 
Fish Commission Steamer Albatross. Mayer found thirty-one 
species and varieties from the Philippines in the Albatross col- 
lection. The forms reported in my paper (1914) from the col- 
lection of the University of the Philippines added seven to this 
number, and the new species described in the present paper 
makes a total of thirty-nine species and varieties of scypho- 
medusan jellyfishes known from Philippine waters. 
This is a surprisingly large number when the smaller numbers 
found in other better-known regions and the incompleteness of 
the collections here are taken into consideration. Mayer (1915, 
p. 160) says: 
It is evident that the region of the Philippines is very rich in scyphome- 
dusse, for off the far better-known Atlantic coast of the United States 
there are but 25 species of scyphomedusae and only 4 of these are Rhi- 
zostomae, while among the 38 species taken by the Albatross, and by Light, 
in the region of the Philippines, 22 are Rhizostomag. Among these 38 
species 15 were new to science. 
The new form described in this paper is a rhizostomid and 
brings the number of Philippine species belonging to that order 
to twenty-four and the number of species named from Phil- 
ippine materials to sixteen. Of these sixteen species and 
varieties, all but one ( Discomedusa philippina Mayer, 1915) are 
Rhizostomae. It would seem, therefore, that the Philippines have
