Two specimens of this species were found washed upon the 

 beach at Cape Adare. The larger one was injured anteriorly, the 

 smaller measured 6 • 5 cm. in total length, to which the tail contri- 

 buted 1 • 5 cm. It is thus recorded for the first time from the shores 

 of the Antarctic land. I follow Fischer in regarding these Antarctic 

 forms as belonging to the species P. caudatus, Lam. The species 

 seems widely distributed in the southern hemisphere. Dr. Fischer's 

 specimen came from Navarin Island.^ M. de Guerne records the 

 species from Orange Bay, from the Straits of Magellan, and from the 

 Falkland Islands, where indeed a specimen had been obtained by 

 the Antarctic Expedition under Sir James Eoss,^ and Dr. 

 Michaelsen* has described and figured two examples from South 

 Georgia. 



The distribution of this species is a striking case of what is 

 termed the phenomenon of bipolarity. F. caudatus occurs along 

 the coasts of Greenland, Norway, and Great Britain, and in both 

 the North and Baltic Seas, but, except for two specimens referred to
