GEOGRAPHICAL DISTRIBUTION 265 



southern part of South America, and on the shores of the Falkland Islands, as well as 

 in the comparatively shallow waters between the two. 



To this group belong the species S. paradoxa, Fabricius, S. schythei, Liitken, 

 S. convexa, Cunningham, S.gaudichaudii, Aud. et Edw., S. exigiia, Nordenstam, the new 

 species S. kempi, S. orbiciilata, S. nototropis and S. elliptica, and the two doubtful 

 species S. plana, Dana, and S. serrei, Lucas. Of these S. gatidichaudii extends farther 

 north than the rest, the original specimen having been collected near Valparaiso. 



Miers in his list of New Zealand Crustacea includes S. paradoxa, apparently (as 

 Beddard, 18846, p. 80, points out) "on the authority of a specimen at the British 

 Museum", and the same collection of Crustacea contains a single example of a species 

 which Beddard identifies as S. schythei, which is also labelled " New Zealand ". Beddard 

 continues : " I believe the locaHty is not authenticated beyond a doubt ". With the excep- 

 tion of these two specimens, the species of this group so far collected are restricted to 

 the above-mentioned localities. 



(2) Those which occur within the Antarctic Convergence, on the shores of the South 

 Sandwich Islands, South Georgia, the South Shetlands and the Palmer Archipelago, as 

 well as off Coats Land (long. 20° W) and Oates Land (long. 155° E). 



To this group belong S. beddardi, Caiman, S. glacialis, Tattersall, S. gerlachei, 

 Monod, S. bouvieri, Richardson, S. polita, Pfeffer, S. pagenstecheri, Pfefi^er, S. polaris, 

 Richardson, S. laevis, Richardson, S. cormita, Studer, S. trilobitoides, Eights, S. septem- 

 carinata, Miers, and the two new species, S. aspera and S. platygaster. 



In Beddard's description of S. cornuta (18846, pp. 52 and 53: iS. trilobitoides of this 

 paper), an error occurs in the list of stations at which the species was collected. The 

 longitude in each case is given as west of Greenwich, with the result that the given 

 stations lie within the Continent of South America. The actual stations are situated 

 around the shores of Kerguelen in corresponding longitudes east of Greenwich. With 

 the exception of a record of doubtful value (that of a specimen of S. trilobitoides de- 

 scribed by Eights from the stomach of a fish collected in Patagonian waters), the species 

 found within the Antarctic Convergence are all different from those present in the 

 South American-Falkland Islands area. 



(3) Those species which are found around the shores of Kerguelen Island, Crozet 

 Island, Marion Island, and Prince Edward Island. These localities with the exception 

 of Kerguelen, lie north of the convergence, considerably farther east than either of the 

 localities referred to in groups (i) and (2) above. Kerguelen Island actually lies on the 

 convergence, its southern shores being within it. 



With the exception of S. latifrons. White, which is also recorded from Auckland 

 Island, New Zealand, the species belonging to this group — namely, S. cornuta, Studer, 

 S. trilobitoides, Eights, and S. septemcarinata, Miers — are also members of group (2) above. 



(4) This group contains the species which are found off the shores of South and East 

 Australia. These are: S. australiensis, Beddard, S. bakeri, Chilton, S. mimita, Beddard, 

 S. elongata, Beddard, S. tuber culata, Grube, S. lo?igicaudata, Beddard, S. pallida, 

 Beddard, and S. yongei, Hale, from the Barrier Reef.
