 One or several specimens from the above localities. They are 

 large animals on the whole, about 50 mm. long, a few reach a length 

 of 60 — 70 mm.

There is a very small specimen in the collection, ca. 6 mm long. 

 To make certain of the identity of the species, I have had material 

 on loan from the Christiania Museum aud there is scarcely any doubt, 

 that the specimen belongs to the species mentioned. The ditlerences 

 from the Norwegian specimens, which come from Vadsø, are not 

 greater than might be due to the small size of the individual, per- 

 haps also the locality. The red and reddish-yellow colour, which is 

 distinct in the Norwegian specimens and which is also mentioned by 

 Mc Intosh, is not conspicuous in the individual of the Danmark 

 Expedition, which is a uniform muddy gray over the whole. The 

 dorsal, fihform papillæ seem also somewhat longer in proportion to 

 the size of the animal than in the Norwegian specimens. The bristles 

 agree very well with the figures given by Mc Intosh and G. Ar. Han- 

 sen, but the indications of the joints in the ventral bristles are scar- 

 cely so conspicuous. Mc Intosh figures a fragment of a specimen 

 from Finmark; I have taken the opportunity to give a figure of the 

 form of the specimen of the Danmark Expedition, PI. XXIX, fig. 11.
