ly turns over when in the water, with singular ce- 

 lerity, and swims with equal ease in every position. 

 The four feet raised in the figure above the back, 

 are made use of in that position, whenever its back 

 comes in contact with any solid substance. This 

 species occurs in all parts of the Spitzbergen Sea, 

 and at the greatest distance from land ; it inhabits 

 the superficial water, and affords food for whales and 

 birds. 



Gammarus ? — Another small species of 



tliis family, was found in large quantities in the 

 stomach and mouth of some mysticete. It is re- 

 markable for the largeness of its eyes. 



Cancer Pulex (Linne). — Taken by Captain 

 Phipps in a trawl, near the coast of Spitzbergen. 



Cancer Boreas (Phipps.) — This singular spe- 

 cies of crab, was first described and figured by Cap- 

 tain Phipps ^. It was found in the stomach of a 

 seal. An animal that I have occasionally met with, 

 resembles this species in several of its characters. It 

 is figured (from an indifferent drawing, however,) in 

 PI. XVI. Fig. 18. 



Cancer Ampulla (Phipps). — Found by Cap- 

 tain Phipps f in the stomach of a seal ; by myself in 

 the stomach of a shark. 



Cancer Nugax (Phipps.) — Taken in the trawl 

 by Captain Pliipps, near Moffen island X.
