Hydrozoa. 3 1 3 



EUCOPIDiE. 



Phialidiutn. 



Two specimens in fairly good condition. 



It is impossible to determine the species, as the marginal sense 

 organs are not visible. The occurrence of this medusa at Cape Adare 

 indicates that hydroids belonging to the genera, Clytia, C'ampanuUna, 

 etc., are likely to be found in the neighbourhood. 



Taken on 27th November, 1899. 



NARCOMEDUS^. 



SOLMARIID-ffi. 



Soliniindella. 



Three specimens. 



Umbrella about 5 mm. in height, 6 mm. in width. Two 

 tentacles. Large marginal lobes. 



The specimens are in rather bad condition and contracted. 

 Sense organs are not visible. It is impossible to determine the 

 species. The position of the tentacles clearly shows that these 

 medusae belong to the genus Solmundella. 



Taken on 10th May, 1899. 



STAUROMEDUStE. 



LUCERNARIIDJE, 



Lucernaria. 



There are two very hne specimens, fortunately in an excellent 

 state of preservation. 



Both specimens are, however, in a contracted condition, and have 

 the eight arms curved inwards, completely hiding the interior of the 

 umbrella. 



The largest measures GO mm. x 60 mm. in its present condition.
