Family NAUSITHOIDAE, Claus, 1878 

 Genus Nausithoe, Kolliker, 1853 

 Nausithoe punctata, Kolliker 

 St. 276. 5. viii. 27. 5° 54' S, 11° 19' E, Gulf of Guinea. Young fish trawl, 150-0 m. 

 Four specimens, 4-7 mm. diam. 



St. 86. 24. vi. 26. 33° 25' S, 6° 31' E, west of Cape of Good Hope. 4J- m. tow-net, 1000 (-0) m. 

 One specimen, 7 mm. diam. 



All specimens show the main characters of this very common species : finely punctate 

 surface, broad oviform lappets, central disc without radial furrows, globular equidistant 

 gonads, gastric cirri of each bundle arising in a straight row, no pigment. Umbrella 

 transparent milky, gonads yellowish. Ocelli very faintly pigmented. 



This medusa is a surface form limited to coastal waters, and its range includes the 

 tropical belts of all three great oceans. The Plankton Expedition found it on the north- 

 east coast of South America (Vanhoelfen, 1892) and the Valdivia Expedition (Van- 

 hoeffen, 1903) captured one specimen in the Gulf of Guinea (St. 58) at 200 m. depth.
