The fore extremity has some resemblance to that of the 
mole. It is furnished with four sharp claws, of which the 
two middle are much longer and stronger than the rest, 
and are much hooked. The second claw is considerably 
the largest. There is no appearance of that induration of 
the skin below the claws of this foot, which has been de¬ 
scribed as a double claw, and as peculiar to the male of 
the Hudson’s Bay mouse. The length ot the fore extre¬ 
mity measured, along the curvature of the foot and claws, 
does not exceed 1.1 inch, and is not quite 0.8 in a straight 
line. The longest claw — 0.4 inch. The palms are hairy. 
The posterior extremity is rather longer than the other. 
The foot from the heel to the end of the claws = 0.8 inch. 
It has four claws, of which the three middle are nearly of 
equal length,—but they are much less than those of the 
fore feet. The soles of the feet ar.' thickly covered with a 
white fur, and the hair on the outside of the foot and leg 
descends below the heel. 
Memorandum by Professor Jameson. 
Hitherto no native species of the mouse tribe have bccil 
met with in Greenland, for neither Midler nor Giescckd 
mention any native animals of this description. It is true 
the black rat and the common mouse are enumerated in 
the Fauna Groelandica, but both these are foreigners im¬ 
ported by the shipping. Had Captain Scoresby found 
the brown or black rat, or common mouse on the West 
Coast of Greenland, it would have gone far to settle the 
disputed point in regard to the ancient European settle¬ 
ments in that country. The species here described by 
Dr Traill, from its near affinity to the M. Hudsonitts, be¬ 
longs to the Lemming group, and probably is for West 
Greenland what the common Lemming is for Europe ;
