There are altogether seventeen species belonging to at least 'sixteen genera, and 

 with the exception of three species, all are either new species or have been recently 

 described as new species from the Antarctic. The ' Discovery ' brought back fourteen 

 species and the ' Southern Cross ' ten, but seven species are common to both collections. 

 The 'Discovery' obtained seven species of the ten collected by the ' Southern Cross.' 

 Eleven species belong to the Hydromedusse and six to the Scyphomedusae. 



The Hydromedusse have nine species belonging to the Anthomedusse and 

 Leptomedusse, which are usually littoral Medusae, but the Trachomedusse and 

 Narcomedusse, which are generally oceanic Medusae, are each represented by a single 

 species. The preponderance of littoral over oceanic species is no doubt due to most 

 of the collecting having been done not far from shore.
