A few individuals of this characteristic Arctic species 

 were tåken on the Expedition, off Spitzbergen, where, too, 

 it was first met with. by Goes. The northern range of 

 distribution extends to the Barcnls Sea. Franz Josephs

208. Aceros phyllonyx, (TVI. Sårs). 



Numerous specimens of this form were collected on 

 the Expedition in divers localities of the tract of ocean 

 we lind to traverse and investigate, from depths reaching 

 1004 fathoms. Of the Stations, one (Stat. 48) lay in the 

 sea east of Icelahd, another (Stat. 240) between Iceland 

 and Jan Mayen, one (Stat. 273) in the Barents Sea, and 

 4 other Stations (Stats. 336, 338, 357, 363) in the sea 

 surrounding Spitzbergen. Moreover, the species was ob-
