No. II. MAMMALIA. 205 



the Arctic species. 1 Fabricius 2 records the fact of this animal 

 in Greenland having eight young ones. Near Lincoln Bay, 

 in lat. 82 8' N., a hare was shot on August 31, 1875, with a 

 very distorted skull, the nasal bones being twisted to the 

 right hand, the incisors of the upper jaw being deflected in 

 the same direction. In the lower jaw only the left incisor 

 was developed, and that protruded in a nearly horizontal 

 direction. This specimen, though in good condition, was 

 small, and weighed only five pounds and a half; another, 

 killed the same day, nine pounds. They were both pure white, 

 with the tips of the ear black. We find, therefore, Lepus 

 glacialis inhabiting the most northern land yet visited, and 

 attaining its normal weight, eight to ten pounds, under 

 apparently very adverse circumstances. Still I must say it is 

 sparsely diffused, and we found that after killing a pair or 

 two out of each valley that afforded any vegetation the race 

 seemed to be extirpated in that district, and I imagine it will 

 take several years to restock the area over which we hunted 

 along the northern shore of Grinnell Land. Examples examined 

 by me contained many parasitical worms, Filaria, in the large 

 intestine.
