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 Hydromeduse and six to the Scyphomeduse. 
The Hydromeduse have nine species belonging to the Anthomeduse and 
Leptomeduse, which are usually littoral Meduse, but the Trachomeduse and 
Narcomedusz, which are generally oceanic Meduse, 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,
