and half an inch in width at the base, is gradually attenuated 
from the root to the extremity, which is more or less sharply 
pointed, and its transverse section would present the form of 
a triangle, but with the angles somewhat rounded, and the 
base of the triangle would be formed by the under surface of 
the claw. As these claws, however, are often much worn by 
usage, they of course will differ in different individuals, and 
sometimes be short and obtuse, ns described by Mr. Ogilby; 
and in specimens kept in confinement, where they are not 
worn away at the point in proportion to their growth at the 
base, they often attain a considerable length, nnd sometimes 
very singular forms. In a specimen of Macropus giganteux 
in the British Museum, the claws of the fore foot, from some 
such cause, have attained the length of from two, to three or 
four inches, and are spirally twisted I suspect the M. 
leptonyx will prove to he founded upon a young specimen of 
M. rujicollis .
