MEDUSA. 5 
The nine species belonging to the Anthomeduse and Leptomeduse are probably 
all liberated from hydroids, which have still to be found. In the report on the 
Hydroids collected by the ‘Discovery’ Messrs. Hickson and Gravely (1907) draw 
attention to the fact that out of twenty-three species of Hydroids found in McMurdo 
Sound not one exhibits free-swimming medusiform gonophores. When we take into 
consideration the difficulties under which Mr. Hodgson worked, and the very small 
area of ground scraped by the trawl and dredge, there seem to be good reasons for 
presuming that more species have still to be recorded. 
The Scyphomedusee are represented by six species, of which two, belonging to 
Periphylla and Atolla, have a wide geographical range, and four are at present 
confined to the Antarctic region. 
The reports on the Meduse collected by the recent expeditions to the Antarctic 
have now been published, and I give a list of the species found south of latitude 60° 8.
