The list showing the species recorded from each station gives a clear insight into the 

 distribution of species within the Antarctic and sub-Antarctic zones. Taken m con- 

 iunction with my table of Antarctic species (1929, PP- 394-40i)> there appears to be no 

 really marked change in the fauna at Graham Land, where the species are dommantly 

 Antarctic. The same is true for the South Shetlands; but at South Georgia there^are, 

 in addition to numerous Antarctic species, a number common to that locality and the 

 Falkland Islands, and a few common to it and the mainland of South America. Around 

 the Falkland Islands there are still many Antarctic species to be found; but the 

 character of the sponge fauna is more that of the southern regions of the South American 

 continent (e.g. Patagonia and Chile). One Antarctic and South American species 

 is also recorded with this report (see p. 325) from the False Bay region of South 



Takhia the records contained in this report in conjunction with my previous papers 



(1029, Terra Nova Report, and 1930, Senckenbergiana) it becomes evident that there 



s no real distinction to be made, so far as sponges are concerned, between the faunas 



of the Antarctic or sub-Antarctic, nor is there any marked difference in the Magellan
