to Bay it seems as if these formations are thrown off in spring, 

 at the same time as the hair change takes place; at any rate, 

 the lemmings, caught in June in summer dress during the ex- 

 pedition of Ryder, had not such protuberances. 



The lemming has many enemies in its native country: 

 fox, ermine, snowy-owl, Buffon's skua, raven; the gulps of 

 birds of prey that I saw, for instance, at Cape Dalton in Turner 

 Sund and in other places, were full of hairs and skeleton parts 

 of the lemming. 



Remains of lemming have been found, by Ryder, in the Eskimo 

 kitchen-midden at Cape Stewart (Ryder, 1. c, p. 288). 



At AngmagsaUk the lemming is known as little as on the 

 west coast, and it was never seen during Amdrup's boat ex- 

 cursions. 



Canis lagopiis L. Arctic Fox. 



The Arctic Fox is the only terrestrial mammal that lives 

 over the whole of Greenland. In Northeast Greenland it was 

 already observed by Clavering, who saw it on August 20, 1823 

 at Jordan Hill, but it is not mentioned by Scoresby. Several 

 foxes were seen during the second German arctic expedition, 

 a single time many together; and in winter foxes often came 

 up to «Germania» , when staying in Germaniahafen in Sabine 

 Island. During the expedition of Ryder it was commonly seen 

 in Scoresby Sund, in winter a dozen were caught near the 

 station-house in Danmarks , and Bay has seen several of 

 its dens. Nathorst saw little of it; one was seen at Ryder's 

 Elv, another in Ymer's Island, and a fox's den was found in 

 Maria Island. 



The arctic fox is found not only on land, but it also goes 

 far out on the floating ice, and is not seldom killed by the 

 whalers on the ice. Dr. Buchholz, drifting down together with the 

 Hansa-men along the coast of East Greenland, has seen the
