Lists of Species found within definite areas during the cruise of 



THE " SeaLARK." 



I have not prepared lists of medusse taken in every tiaul of the nets nor for every 

 station, but have grouped together the stations under convenient geographical headings. 

 The longest list belongs to the Chagos Archipelago, and that may be probably due to more 

 collecting of plankton having been done witliin that area, than in other areas, such as at 

 Mauritius. Professor Gardiner made serial hauls at different depths and also hauls at 

 definite intervals of time at several of the stations. I made records of the medusse 

 found in every haul, but failed to obtain any reliable results owing to the scarcity of 

 specimens.
