There is only one specimen, which lacks the hindmost rings. 

 There is no doubt regarding its identity; through the kindness of 

 Prof. Thékl I have had on loan the single specimen preserved in 

 Riksmuseet of Stockholm, presumably the "specimen unicum man- 

 cum", which Malm(iHKn mentions from the Finmark. A few months 

 ago Dr. \\'()LLEH.KK from Christiania Museum was here and asked 

 permission to examine the animal. The drawings he then made of 

 it have been given me with the greatest friendliness for publication 

 in the present paper. 



The Danmark Expedition's specimen is a good deal smaller than 

 Malmgukx's; it is only Ио mm. in length. Owing to its state of 

 preservation it is not possible to state with certainty the number 

 of the segments present; they are about 45. — The cephalic lobe, 

 the dorsal aspect of which is slightly arched, is provided with a 

 somewhat prominent margin, which has a straight edge and is beset 

 with ca. 8 small rounded papillae, which g[\e it a slightly wrinkled 

 appearance. The mouth segment is rather large and prominent. On 

 the second to the fifth bristle-bearing rings there are rudimentary 

 ventral parapodia, which, so far as I can see, contain no bristles. 

 These rudimentary parapodia are not mentioned by Malmghen in his 

 description, but they are distinct in his figure (1867. PI. XII, fig. (i8). 

 Ventral bristles begin on the 7th bristle-bearing ring.
