254 DISCOVERY REPORTS 



This is a small species. The largest specimen described by Theel measured only 

 9 mm. in length, and the Discovery specimens were mostly about this size. It was first 

 taken at South Georgia and the Falkland Islands and the Discovery specimens came 

 from much the same area, namely, from South Georgia and from an extensive patch 

 lying to the north of the Falkland Islands along the edge of the continental shelf. It has 

 also been found at Kerguelen, having been taken there by the B.A.N.Z.A.R.E. in 1930. 



The depths in which it was taken were also considerably in excess of these previously 

 recorded. At the Falkland Islands it was taken in 12 m., at South Georgia in depths 

 ranging from 64 to 195 m., and at Kerguelen in 91 m. The range in depth of the 

 Discovery specimens was 150-300 m. 



One of the animals from St. WS 212 had the body full of ova.

Distribution. South Georgia: Theel, loc. cit. 



North of Astrolabe Island, 63° 9' S, 58° 17' W: Theel, loc. cit. 

 Kaiser Wilhelm Land, 66° 2' S, 89° 38' E: Fischer, loc. cit. 

 Occurrence. Falkland Islands: St. WS 840. 368-463 m. One specimen 'from large rock'. 

 South Georgia: St. WS 33. 130 m. One specimen. 



St. 39. 179-235 m. Three very large specimens, one small. 

 St. 42. 120-204 m. Two medium-sized specimens. 

 St. 123. 230-250 m. One medium-sized specimen, six small. 

 St. 149. 200-234 m. Five small to medium specimens. 

 St. 159. 160 m. One very small specimen. 

 South Shetlands: St. 196. 720 m. Three small specimens, one with the body full 

 of ova. 



These animals agreed well with Theel's description and no comment need be made 

 except that the tentacles may be more numerous than the original description stated. 

 The species is evidently a fairly widespread one from south of the Falklands to the 

 South Shetlands. The Discovery stations are from considerably deeper water than the 

 previous records.
