Cuvier in his splendid work. A living specimen in 
the collection at Exeter Change has since been noticed 
by Mr. Griffith im his Vertebrated Animals. We are 
not aware that any other specimens, either living or 
dead, have fallen under the observation of zoologists ; 
and we therefore feel justified in regarding it as a 
singularly rare and interesting creature. 
In the preceding article we have briefly stated the 
characters of the grand division of the Quadrumanous 
Order, to which belong both the Slow-paced Lemur or 
Loris, and the true Lemurs of modern authors. It 
therefore only remains in the present instance to point 
out in what respects the latter genus differs from all 
the other groups which constitute the family. These 
differences consist principally in the number and posi- 
tion of its teeth; the form of its head; and the propor- 
tional length of its limbs and tail. In the true Lemurs 
the incisor teeth are six in number in the lower jaw, 
long, slender, and sloping forwards; and four in the 
upper, ranged in pairs with a vacant space between, 
the bone being too thin at its anterior part to admit of 
the implantation of teeth within its substance. The 
canines of the lower jaw differ from those of the other 
Quadrumanous families in their short triangular shape, 
and in their locking in, when the mouth is closed, 
behind those of the upper, which are long, very much 
curved, and extremely thin. The cheek teeth consist 
of three false and as many true molars on either side 
of the upper jaw; and of only two false and three true 
molars in the lower. The head is elongated, triangular, 
and pointed, with a sharp projecting muzzle. The 
posterior limbs are little longer than the anterior; the 
tail is long, thick, and bushy; and the whole body is 
covered with thick close woolly hair to such a degree 
as nearly to double in appearance its real bulk. In
