Caiman, 1915, pp. 10 and 11, fig. i. 



St. 42. I. iv. 26. Off mouth of Cumberland Bay, South Georgia, from 6-3 miles N 89° E of Jason 

 Light to 4 miles N 39° E of Jason Light, 120-204 m; M. Large otter trawl: i c?, i ?. 



St. 123. 15. xii. 26. Off mouth of Cumberland Bay, South Georgia, from 4-1 miles N 54° E of 

 Larsen Point, to 1-2 miles S 62° W of Merton Rock, 230-250 m.; gy. M. Large otter trawl : i <?, i ?. 



Distribution. Previously recorded from Ross Sea. 



Colossendeis tortipalpis, n.sp. (Figs, zb-e, 36, ^ and 4 a). 



St. 170. 23. ii. 27. Off Cape Bowles, Clarence Island, 61° 25' 30" S, 53° 46' W, 342 m.; R. 

 Large dredge: i ? (holotype), i S and i immature, soft specimen, with C. australis. 



Diagnostic characters. Sixth palpal segment more than three times as long as 

 thick; eighth palpal segment articulated laterally (or termino-laterally) with seventh; 

 proboscis as a rule exceeding 1-5 times the length of the non-segmented trunk; lateral 



1 C.frigida, C. megalonyx and C. rugosa may be co-specific; and C. scoresbii may be only a more northern 

 form of this species. 



- The sixth palpal segment may be rather more than twice as long as wide in C. drakei.
