This medusa is common at the Tortugas, Florida ; as indeed it is also among 

 the Bahama Islands and along the Cuban Coast. It is met with in consider- 

 able numbers in Charleston Harbor, South Carolina ; and occasionally a 

 damaged individual is drifted into Newport Harbor, Rhode Island, by the 

 southerly winds late in the summer months.

This medusa is occasionally met with in June at the Tortugas, Florida. It 

 is found also in the Mediterranean and is widely distributed throughout the 

 tropical regions of the Atlantic (see Maas, O., 1893, Die Craspedoten Medu- 

 sen der Plankton Expedition, Taf. VII.). A very closely allied species is found 

 in the Tropical Pacific (see Agassiz and Mayer, 1898 ; Bull. Mus. Comp. Zool. 

 at Harvard Coll., Vol. XXXII. p. 166). One figure is drawn from a specimen 

 obtained at the Tortugas, Florida.
