nothing to be said, as there are no previous records, except the doubtful egg of 

 Callidina papillosa mentioned by Richters (31). Rlchters gives details of the jaws 

 and teeth of four species from the Gaussberg, and figures them, as well as other details 

 of two of the species. These are insufficient for certain identification, though if the 

 rotifer fauna of the Gaussberg could be studied in life we might have a good guess as 

 to what those four were. As our knowledge at present stands we cannot connect any 

 of them with the species found at Cape Royds, though it may be suggested that the 

 figures five and six on his Plate XVII. may be Callidina constricta, which was the 

 only moss-dwelling species identified at Cape Royds. 



As the thirteen species found at Cape Royds appear to be the first recorded for 

 the continent, we can only study the distribution over the world of those of the 

 species which are not new to science. The distribution is most clearly seen when the 

 facts are given in tabular form. It is not claimed that the records tabulated are 

 complete, but I have given all which I could find. 



TABLE SHOWING THE GENERAL DISTRIBUTION OF ALL RECORDED ANTARCTIC 



ROTIFERA. 



The facts made use of in the above table are compiled in part from the following 

 sources : for the Antarctic from a paper by Richters (31) : for Australasia from Hilgen- 

 dorfs list (19) and from my own unpublished notes which will appear in a later 

 number of this series : for Europe from papers by Bryce, Janson (20), and others : 

 for Africa from a paper by Rousselet (33) and unpublished notes : for N. America 

 from a paper by Jennings (21) and from unpublished notes : for the Arctic Region 

 from papers by Bryce (5), Bergendal (3) and myself (28). 



The new Antarctic species are placed at the top of the list in order that the other 

 facts may be compactly grouped. The facts of distribution of the nine previously
