Campanularia volubilis var. antarctica, Filellum (?) expansum, Sertu- 
larella cumberlandica, and Sertularella glacialis. Four of these have 
not hitherto been found in Antarctic regions : the doubtful Clavatella juv., 
representing a genus unknown from the Antarctic ; the new variety of 
Campanularia volubilis and Filellum expansum, both species hitherto 
known only from the northern hemisphere ; and Sertularella cumberlandica, 
which so far has been found only in a sub-antarctic locality, and that on 
the opposite side of the Antarctic continent. 
The dearth of representatives of the family Plumularidse in the 
Antarctic fauna of this area, as illustrated in this collection and in that of 
the Discovery, is remarkable, especially when one takes into consideration 
the abundance of such forms in the neighbouring; Australian fauna. 
Amongst Antarctic faunas outside the Victoria Land region, this small 
sample appears most to resemble that investigated by the German Antarctic 
Expedition, to the south of Kerguelen.
