Station II. January 13, 1873. Lat, 38° 10' N., long. 9° 14' W. Off Setubal. 470 

 fathoms. Green mud. 



Habitat. — North America, East Coast (Gould) ; Greenland and Iceland (Morch) ; 

 Spitzbergen (Reeve); Barent's Sea (d'Urban); Norway, 30 to 100 fathoms; Behring's 

 Strait (Sars) ; Japan (Liscbke). 



Fossil. — Older and younger glacial beds, Norway (M. Sars). 



This specimen is quite a young shell, having only six whorls, i.e., three beyond the embryonic 

 apex, but on the whole I believe it to be this species. The apex is certainly coarser even than 

 usual, the shoulder below the suture is higher, the first spiral is broader, the third smaller, and those 

 on .the base much more numerous than is customary ; but all these, especially the form of the 

 embryonic apex, are exceedingly variable features in this species. It is a decidedly Arctic form, and 

 has been traced along the Siberian coast to Japan. I have quoted G. O. Sars for its presence at 

 Behring's Strait, but Dall, in his List of Mollusca from that region, does not mention it. Its occur- 

 rence so far south in the Atlantic as the coast of Portugal is interesting. 



The identity of this species with the Fusus antiquus, Linne, is very strongly supported, and is an 

 opinion deserving the utmost respect. If it has not been followed here, the reason is, that though 

 my opportunities for comparison have been rather limited, I have an impression that the apex in the 

 two species is different. On this point I had hoped for fuller information from Mr Herman Friele 

 of Bergen, in his great work on the Mollusca of the Norwegian Northern Expedition, some of the
