MEDUSA OF THE WORLD. 



Tabular Description of the Medusa of Slabberia. 



'Distinguished by 4 small, isolated (glandular?) bodies upon its 4 radial-canals. Hartlaub, 1907, believes these to be gonads 

 which become mature only in old medusae. 



2 Distinguished by its quite thick tentacles, each ending in a single, knob-like cluster of nematocysts. 



3 Separated from S. strangulata only by its long, slender tentacles and uniform dull-yellow color. 



4 Hydroid a Syncoryne. Medusa distinguished by numerous total or partial rings of nettling cells which are developed over 



outer halves of tentacles. When young medusa-buds are borne on manubrium of free medusa. 

 5 Is this a fully developed, mature condition of 5. catenata(t). 

 6 Distinguished by terminal "suctorial cups" on its tentacles and numerous glands (?) which line radial-canals.
