Other accounts (see references above) describe variations of con- 

 siderable magnitude, as follows: 



Scoloplos tnawsoni Benham (1921, pp. 78-81), from the Australian 

 Antarctic region, has been referred to Haploscoloplos kerguelensis by 

 Monro (1936, p. 160). 



Scoloplos kerguelensis, sensu Fauvel (1932a, pp. 165-167), from 

 India in a small creek at low water, differs from typical representatives 

 in its high thoracic count (18-20 segments); thoracic parapodia are 

 plain except for the last 3 to 6, which have a small conical notopodial 

 postsetal lobe and an inconspicuous lobe at the midlength of the neuro- 

 podial ridge; branchiae are first present from segment 21 and are short, 

 broad, triangular in shape. 



Haploscoloplos kerguelensis, sensu Okuda (1937 and 1938) from 

 Japan more nearly resembles H. elongatus (see above) in that branchiae 

 are present on the last thoracic segment and the transition from thorax 

 to abdomen is at 15/16 to 19/20. 



Distribution. — Haploscoloplos kerguelensis comes originally from 

 Kerguelen Islands in 110-120 fathoms (Mcintosh, 1885); it is re- 

 ported from Patagonia (Ehlers, 1897, p. 97), from Antarctica in 8-10 

 fathoms (Willey, 1902, p. 275), Port Lockroy, Antarctica, in 28 meters 

 (Gravier, 1911, p. 108), Falkland Islands (Fauvel, 1916, p. 445), 

 India (Fauvel, 1932a, p. 165), South Orkney Islands (Monro, 1936, 

 p. 160) and Japan (Okuda, 1937 and 1938). As indicated above, some 

 of these records may refer to other species.
