MR.  R.  OWEN  ON  THE  STOMACH  OF  SEMNOPITHECUS. 
Vampyre  Bat  will  be  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  Bradypoda  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  Quadrumanous  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  Linnseus  considered  to  be  so 
closely  connected  with  them.
