The earthworm described in the present paper was collected 

 in Shoe Island, a small island near Auckland Island, by one 

 of the officers of the steamship ' Discovery,^ on her return 

 from the Antarctic Expedition (1902). I have to express 

 my sincere thanks to Prof. F. J. Bell, who sent me the worm 

 for examination.
