Greenland. 



Animal black, mantle dirty yellow, with black spots, which are to be seen 

 through the shell. Foot long, narrow. Eye-peduncles long, and proportionally 

 rather thick. Tentacles short, blunt (Morch). 



Fig. 45 is copied from an original drawing by Morch, 1. c. I have not seen 

 the species, which certainly must be nearly allied to, if not identical with, fulvus.
