P. trilobosa was taken by the ' Gauss'. 1 



SolmundeUa sp.

St. WS30 ... 8 at 67 m.

SolmundeUa was the commonest medusa taken in the Antarctic both by the National 

 Antarctic (Discovery) 2 and Gauss 1 Expeditions. It was also taken by the ' Southern 

 Cross' 3 and 'Belgica' 4 ; and by the 'Francaise' 5 at the Falkland Islands.

It is seen that in many instances these forms occurred in the warmer intermediate 

 layer, i.e. 1000-750 m., and never in the purely Antarctic surface water, although at 

 times in a mixture of the two. 



The only previous record of this genus in the Antarctic appears to be the single 

 specimen of H. racovitzae taken by the ' Belgica ' 4 in 70 09' S, 82 35' W. 



Trachynemidae. 

 St. 125 1 at 1000-750111. St. WS70 ... 2 at 1000-750 m. 



In the former case in the warmer intermediate water and in the latter in a mixture of 

 this and the sub-Antarctic surface water. 



Siphonophora 



Chuniphyes midtidentata, Leres and Van Riemsdigk. 

 St. WS 63 ... 3 at 1000-750 m. 



This is in the warm intermediate water, possibly of Pacific origin (see footnote, p. 8). 

 It was taken by the ' Albatross ' in the east tropical Pacific. It has not been taken in the 

 Antarctic Zone before.
