TEREBELLIDAE 193 



St. WS 27. 19. xii. 26. 53° 55' 00" S, 38° 01' 00" W. 107 m. Gear N 100 H. (Net touched 

 bottom.) Bottom: gravel. Two specimens.

St. MS 14. 17. ii. 25. From 1-5 miles SE x S to 1-5 miles S | W of Sappho Point, East 

 Cumberland Bay, South Georgia. 190-110 m. Gear DS. Fifteen specimens, with numerous tubes, 

 mud and debris. 



St. MS 68. 2. iii. 26. East Cumberland Bay, South Georgia. 1-7 miles S J E to 8| cables 

 SE X E of Sappho Point. 220-247 m. Gear NRL. One specimen. 



St. MS 71. 9. iii. 26. East Cumberland Bay, South Georgia. 9I cables E x S to 1-2 miles

Remarks. An example from St. MS 68 measures 190 mm. for about 105 segments. 

 Only the last 23 segments are without notopods. I believe that in the southern forms 

 belonging to this species the gills more nearly meet in the mid-dorsal line than in the 

 northern forms. In some examples there is only the width of about two gills separating 

 the tufts of branchiae.
