MR.  E.  T.  BENNETT  ON  THE  M'HORR  ANTELOPE. 
7 
the  Berlin  Transactions,  and  in  the  work  of  M.  Riippell,  appears  to  me  to  furnish  the 
most  convincing  proof  that  neither  the  Nanguer  nor  the  M'horr  can  possibly  represent 
intermediate  stages  of  the  same  animal.  I  therefore  consider  myself  fully  justified  in 
assigning  the  following  differential  names  and  characters  to  each,  I  have  not  retained 
for  either  of  them  the  name  of  Dama,  because,  as  far  as  the  essential  character  goes,  it 
seems  to  be  equally  applicable  to  all.  Perhaps,  however,  on  strict  principles  of  nomen- 
clature, it  ought  to  have  been  retained  for  BufFon's  animal,  to  which,  as  a  trivial  name, 
it  was  unquestionably  first  applied.

'  The  plate  of  Ehrenberg  above  referred  to,  as  containing  figures  of  the  Nubian  species,  was  published,  I 
believe,  in  1829  ;  but  the  illustrative  text,  which  bears  date  in  August  1832,  did  not  reach  this  country  until 
after  the  reading  of  the  present  paper.  In  it  the  learned  author  expresses  his  doubts  of  the  correctness  of  the 
Plinian  synonym  as  applied  either  to  the  Addra  or  the  Nanguer ;  and  considers  the  word  Dama,  as  used  by 
other  classical  writers,  to  be  a  common  appellation  of  all  cervine  beasts  of  chase.  He  is  of  opinion  that  the 
species  of  Antelopes  are  circumscribed  within  very  narrow  limits  ;  and  for  this  reason,  as  well  as  on  account  of 
the  shorter  and  thicker  neck,  and  much  shorter  horns  of  the  Senegalese  animal,  he  seems  inclined  to  regard  the 
Dama  of  Eastern  and  Western  Africa  as  distinct,  but  does  not  venture  on  changing  the  received  denomination. 
Of  the  M'horr  he  had  no  knowledge.  The  particulars  of  the  habits  of  the  Addra,  as  observed  by  himself  in 
the  territory  of  Dongola,  to  which  it  would  appear  to  be  almost  confined  ;  and  the  descriptions  and  minute  ad- 
measurements of  the  adult  male,  its  skeleton,  the  female,  and  the  young  of  both  sexes,  render  this  a  highly 
valuable  addition  to  our  stock  of  information  relative  to  the  Eastern  animal.
