THE ENTELLUS MONKEY. 83 
accidental resemblance to that of the Ceylonese animal ; 
or, which is the more probable conjecture, must have 
been transferred from it to the African, by the igno- 
rance or carelessness of the showman from whom 
M. Allamand received it. The similarity of sound, 
connected with absolute identity both of locality and 
habits, would tempt us also to associate with the pre- 
sent species the Rillowes of Knox’s Historical Relation 
of the Island of Ceylon, were it not that there are 
some points in his description of those animals which 
could searcely be reconciled with such a combination. 
It is more than probable that many of the earlier 
accounts of the large gray Monkeys of Bengal and the 
Malabar coast, which are spoken of by travellers as 
objects of veneration to the natives, and which have 
been usually referred to the Malbrouck of Buffon, are 
in reality applicable to the animal now before us. The 
Malbrouck, there is every reason to believe, does not 
inhabit India, but is, like all the other Cercopitheci, a 
native of Africa. 
The genus Semnopithecus of M. F. Cuvier, of which 
the Entellus offers a truly characteristic example, is 
distinguished from the other Monkeys of the Old World 
by several remarkable characters, affecting not only its 
outward form but also some essential parts of its inter- 
nal organization. In the degree of their intelligence, 
the form of their heads, and the general outline of 
their proportions, the species which compose it seem 
to occupy an intermediate station between two other 
purely Asiatic groups, the Gibbons of Button, which 
are the Hylobates of modern systematists, and the 
Macaques, of which the Wanderoo may be regarded 
as the type. Their bodies are slightly made; their 
limbs long and slender; their tails of great length, 
considerably exceeding that of the body; their callo-
