not only a rich but a very characteristic rhizostomid fauna. 
There is no doubt in my mind that more systematic collections 
with the proper facilities will increase very considerably not only 
the total of species but the number of new species from the 
Archipelago. 
The list of species and varieties known from the Philippines, 
with notes on distribution, follows. Names and dates in paren- 
theses refer to the recorders and the dates of publication.
