Some of the results obtained by this expedition for the geographical distribution of 

 medusae are rather interesting. 



Turritopsis nutricula had not before been found in the Indian Ocean. It is a well- 

 known species on the North Atlantic coast of the United States, south of Cape Cod, and 

 it also has quite recently been recorded from Japan. 



Tiaropsis rosea and Euphysora higelowi have had their range extended westwards 

 from the Malay area. 



Prohoscidactyla tropica is the most interesting find in the collection ; it has not 

 been recorded since Huxley first found it in Louisiade Archipelago (Malay ai-ea). 



Olindias singularis occurs at Chagos, which is not so far from the Maldives, where 

 it was first discovered. Since its discovery it has been found far away in the middle of 

 the Pacific among the Paumotu Isles. 



Sminthea eurygaster is new to the Indian Ocean ; its old records are for the 

 Mediterranean, the Bay of Biscay, and in the Atlantic as far south as Brazil.
