The height over the anus amounts to 9,5—14,2% of the total length (in the 

 young, 8 — 9,6%). The length of the head in the males is 23,6 — 27,6%, in the females 

 22,4 — 25,2% of the total length. The tail is somewhat longer than the head and 

 trunk together, as the distance between the snout and the anus is in the males 

 43,7 — 47%,, in the females 38,2 — 45,6% of the total length. The colour is uniformly 

 reddish gray or brown gray (in living specimens, yellow brown to chocolate colour), 

 without bands or spots; the gill-covers and fins are dark brown toward the margins. 

 The scales are unusually small, covering the whole of the body as far as the head, 

 and the base of the fins also in the fully grown; in the younger, the middle part of 

 the belly, the fins and along their bases are most often naked. Lateral line ventral 1 ). 

 Pyloric appendages 2 2 ). The size reaches to ca. 560 mm.

Prof. Collett has given detailed information with regard to the numerous specimens taken 

 on the Nqrw. North-Atlantic Expedition, representing the species from the younger stages up to 

 510 mm.; a new and searching description is therefore unnecessary. I shall simply content myself 

 with making some comments, in part supplementary, in part for correction. 



I give below the measurements of 17 specimens from the Ingolf Expedition; the sex is stated 

 where it could be determined with certainty, which is already possible at a length of ca. 100 mm. 



') Iu well-preserved specimens a series of dorsal pores remote from one another, can also be seen. 

 2 ) I do not agree here with Collett, who states that the pyloric appendages are wanting.
