A single young medusa of thi-s species was found at the Tortugas, Florida,

 medusae described by Fewkes, 1883, from the Bermuda Islands. The adult 

 medusa has not been found.

This Siphonophore appears occasionally in great numbers at the Tortugas, 

 Florida, especially when southerly breezes drive the surface waters of the Gulf 

 Stream upon the Florida Reefs. It is common among the Bahama Islands and 

 along the Cuban coast, and isolated individuals are often carried far to the 

 northward by the Gulf Stream, specimens having been taken in Newport 

 Harbor, Rhode Island.
