70 MR. R. OWEN ON THE STOMACH OF SEMNOPITHECUS. 
Vampyre Bat willbe found to accord with the bloodthirsty habits so repeatedly ascribed 
to it; and in corroboration of which Professor Grant, in his late Lectures before the 
Society, gave some additional observations. 
The complicated stomachs of the Bradypode are also well known; they approach 
in their external form more nearly to those of the true Ruminants. The chambers 
into which the stomach of the Sloth is divided, are not, however, characterized by 
the difference of texture of the lining membrane which exists in the Ruminants: they 
present only a difference in the degree of vascularity and villosity, and in that respect 
are analogous to the complicated stomach of the Quadrwmanous genus. . 
To those who are more especially interested in investigating the natural affinities of 
the animal kingdom, it must be highly gratifying to find the Quadrumana manifesting 
new instances of relation to genera which the immortal Linnzus considered to be so 
closely connected with them.
