 ^^Tliis starfish differs in sei'eral 

 resi:)ects from the typical form, but 

 we have not thought it right to raise 

 it to an independent species. The 

 propoiiion l)etween the small and 

 great radius is in examples of 

 108-124 mm's size as 1 : ^-Zh The 

 marginal plates, wliich in examples 

 of the size just stated are 38-40 in 

 niunber, are at the arm base 4.1 mm 

 broad, 2 mm high and the paxillar 

 area 9 mm broad ; in the middle of 

 the arm they are 2 mm broad, 1.5 

 mm high, and the paxillar area 2.8 

 mm broad. The adambulacral plates 

 are next the ambulacral fmTow arm- 

 ed ^vith 4, 5 to 6 flat, rather long 

 papillfe, placed at some distance 

 from one another ; usually however 

 there are 5. The mouth plates 

 (maxillae) have on each side 8-9 

 sti'ong papillœ. The colour is choc- 

 olate brown on the dorsal side, 

 gi'eyish white on the ventral side. 

 Comparing now the typical ArcJiaster 

 Parclii with om* variety, it is ap- 

 parent that tliis has a much broader 

 disk and longer arms, that the mar- 

 ginal x^l'i-tes are more numerous, 

 naiTower and thinner, and that the 

 j)axillar area is broader. The ad- 

 ambulacral plates have more and 

 longer papilla), and this is also the 

 case with the mouth-plates, and 

 finally the colom' is quite différent.

 published in their Ml report mentioned further on, but have kept closer to the Norwegian 

 text.
