Greenland, Lemming, earless, with a sharp nose; fore-feet hairy beneath, with four toes, armed with claws, having 
sharp cylindrical points ; a dark stripe along the middle of the back. 
Foster, in the Philosophical Transactions, notices a skin brought from Churchill, 
evidently of a lemming, but in too imperfect a state to enable him to determine 
the species, Both he and Pennant were inclined to refer it to the Mus lagurus of 
Pallas, because it agreed with that animal in having a dark line along the back; it 
is more probable, however, that the skin belonged to the species which forms the 
subject of this article, which has also a dark dorsal stripe, and is certainly an 
inhabitant of Hudson’s Bay. It was first described, and the specific name affixed, 
by Dr. Traill, froman individual procured by Captain Scoresby, on the east coast 
of Greenland; and on Captain Parry’s second expedition a considerable number 
were caught in Repulse Bay, and are described in the Appendix above quoted. 
They were found in similar situations with the Hudson’s Bay lemming, and were 
considered to be the females of that species, by the officers of the expedition, and 
as [such noted in their journals. A number of them being put into a cage, 
fought until they destroyed each other. 
DESCRIPTION. 
Size—rather less than the water-rat (Arvicola amphibius). In general form they resemble 
the other lemmings. Head rounded, narrower than the body, tapering slightly from the 
auditory openings to the eyes, but from the latter the acumination is more sudden, and it 
terminates in an acute nose. ‘The general colour of the superior and lateral parts of the 
head, is the same with that of the back. There are no external ears, but the site of the 
auditory opening is denoted by an obscure transverse brownish streak in the fur. The eyes 
are near each other, and small. The fur on the cheeks is a little puffed up, has a rufous 
tinge, and is bounded posteriorly by an obscure blackish semicircular line, which commences
