ZOOLOGY. 
clxxxix 
are not mentioned by Fabricius. They live in summer in burrows, and in 
winter in nests of moss on the surface of the ground beneath the snow, rarely 
going abroad during the severity of winter. This species is distin- 
guished by the prolongation of the two middle toes of the fore feet 
into a pointed callus beneath the claw, making the toes appear double 
clawed : the same peculiarity is observable in the outer toes, but in a 
much less degree, and it is altogether less marked in the female and young, 
than in the male. The tail is not quite half an inch in length, terminating 
with long stiff hairs, which alone appear beyond the fur ; it is erroneously 
stated in the Rhgne Animale to be without a tail. The length of a full grown 
male specimen is less than six inches, the females are not so large. The fur is 
soft and long, deep gray at the base, and white at the points in winter ; the 
white being mottled in summer with black and reddish brown on the back, 
and with reddish brown on the under parts. The fore-feet have four toes with 
claws, and the rudiment of a fifth toe without a claw, at the hinder part of 
the fore foot. 
8. Bos Moscatus. Musk Ox. 
This species of ox inhabits the North Georgian Islands in the summer months, 
but being less numerous than the rein-deer, and more difficult to approach, 
three individuals only were killed, all of which were bulls. They arrived in 
Melville Island in the middle of May, crossing the ice from the southward, 
and quitted it on their return towards the end of September. The musk ox 
may be further stated, on Esquimaux information, to inhabit the country on the 
west of Davis’ Strait, and on the north of Baffin’s Bay : as a head and horns 
and a drawing of a bull being shewn to the Esquimaux of the west coast of 
Davis’ Strait who were communicated with on the 7th of September, were 
immediately recognised, and the animal called by the name of Umingmack ; 
this is evidently the same with the Umimak of the Esquimaux of Wolstenholme 
Sound, who were visited by the former expedition, and of which nothing 
more could be learnt at the time from their description than that it was a
