Beschreibung der amerikanischen Varietät nach A. G. Mayer 1910: 

 „Adult Medusa. - - Bell ellipsoidal in form and about 3,5 mm in height. 

 Gelatinous substance not very thick, but quite tough and rigit. There are 

 about 24—32 marginal tentacles which are about as long as the bell-height. 

 The tentacles are not very flexible and are usually carried curled upward. 

 The tentacle-bulbs are well developed and are filled with ehtoderm pigment 

 granules. The Velum is well developed. There are four straight and narrow 

 radial-canals. The manubrium is flask-shaped and there is no peduncle. The 

 mouth opening is surrounded by 4 short, radially situated, unbranched, oral 

 tentacles, each of which terminates in a knobshaped Cluster of nematoeysts. 

 The ripe ova and spermatozoa are found in the 4 interradii within the ectoderm 

 of the manubrium. According to Ishikawa and Bunting the ova originate in 

 the entoderm but the sperm originates and remains in the ectoderm. When 

 the medusa is mature both ova and sperm are found in the ectoderm of the 

 stomach. In the female the ova are large and prominent and are spherical 

 in form. The Entoderm of the manubrium and of the Tentacle bulbs is red 

 or brown to red, in color."
