variation in the width of the black band across the head, 
white-fronted The white-fronted lemur ( L. albifrons) appears to be restricted 
Lemur. to the north-east coast of Madagascar. It is mainly distinguished 
from the allied species by its colour; its most distinctive feature being a broad 
band of white woolly hairs extending across the forehead, and including the base 
of the ears, the cheeks, and part of the throat and neck. The prevailing colour of 
the back and flanks is a grizzled brown, tinged with red; the long muzzle and 
face, together with the hands and feet, and the end of the tail being black. The 
under-parts and inner surfaces of the limbs are whitish-grey. This pretty lemur

was first described by the French naturalist Geoft'roy St. Hilaire ; and was exhibited 
in the London Zoological Gardens as far back as 1830. 
Black-fronted This ( L. nigrifrons ) is another closely allied lemur, also first made 
Lemur. known to science by the naturalist last mentioned. In comparing it 
with the preceding species, E. T. Bennett, who had the opportunity of seeing living 
examples of both, observes that “ their size, it is true, is nearly equal, and there is 
little if any difference in their form; but their colours, invariable as we have 
hitherto found them, furnish sufficient ground for regarding them as distinct. The 
present animal has the elongated muzzle of the last, but the black colour embraces 
in it the forehead and sides of the face, as well as the base of the muzzle; and 
the hair on the former parts, instead of being long and woolly, is short, smooth, 
and even. While the black is thus extended backwards over the head, it is bounded 
on the fore part of the muzzle, which instead of being uniform in colour, as in the
