1 This form [Leptoptychaster antarcticus] is unquestionably the southern representative of Leptoptychaster arcticus 

 (Sars) of the North Atlantic, to which it is structurally nearly related. ... It is interesting to note that Leptopty- 

 chaster antarcticus is more nearly related to the distant Arctic form than to the comparatively neighbouring species 

 Leptoptychaster kerguelenensis ; perhaps a more extended series of specimens than we possess at present might lead to 

 Leptoptychaster antarcticus being ranked as a variety only of the northern form. At present I do not feel justified in 

 taking that step.— (Sladen, Zool. Chall. Exp., part 51, p. 192 )
