Neactaeonina edentula Thiele, 191 2, p. 219. 



Type locality. Balfour Bay, 60 fathoms, Royal Sound, Kerguelen I. 



St. 144. Off mouth of Stromness Harbour, South Georgia, from 54 04' S, 36 27' W to 53° 58' S, 36 26' W,

 (one example). 



Height 25-2 mm.; diameter 12-75 mm - (holotype). 

 Height 16-5 mm.; diameter 10-5 mm. (St. 144). 



Dentition. Unfortunately, the teeth became scattered in the only mount I was able to prepare, but 

 individually they resemble those figured by Thiele for cingidata. 



The South Georgian example (St. 144) is slightly more globose than the type, and if this feature 

 should prove to be constant a new species is indicated.
