MR,  E.  T.  BENNETT  ON  THE  M'HORR  ANTELOPE. 
3 
No  other  original  observations  were  made  upon  this  subject  until  the  year  1824, 
when  M.  Lichtenstein  read  before  the  Royal  Academy  at  Berlin  a  Memoir  on  the 
Antelopes  of  North  Africa,  which  was  published  in  1826.  In  this  paper  he  described 
and  figured  the  male,  female,  and  young  of  a  species  of  Antelope  transmitted  from 
Nubia  by  MM.  Ehrenberg  and  Hemprich,  which  he  believed,  notwithstanding  the  extent 
of  geographical  range  thus  indicated,  to  be  identical  with  the  Nanguer  of  Senegal.  In 
the  MS.  notes  of  these  distinguished  travellers,  the  native  name  of  Addra  is  applied  to 
the  animal  in  question.  Figures  of  the  adult  and  young,  evidently  of  the  same  species, 
have  since  been  given,  with  the  same  scientific  and  native  name,  in  M.  Riippell's 
Zoological  Atlas,  from  specimens  obtained  in  Kordofan.  These  specimens  were 
observed  in  the  Frankfort  Museum  by  Colonel  Hamilton  Smith,  who  described  them 
in  Mr.  Griffith's  edition  of  Cuvier's  "  Animal  Kingdom,"  under  the  name  of  Antilope 
ruficollis,  which  seems  to  have  been  originally  attached  to  them  in  that  collection. 
On  comparing  the  figures  and  descriptions  contained  in  the  works  referred  to  with 
each  other,  and  with  two  living  specimens  and  an  imperfect  skin  of  an  Antelope, — for 
which  the  Society  are  indebted  to  the  active  exertions  of  Mr.  Drummond  Hay,  His 
Majesty's  Consul-General  at  Tangier,  and  of  Mr.  Willshire,  Vice-Consul  at  Mogadore, 
and  which  were  brought  from  the  territories  of  the  Sheikh  of  Wednoon  (twelve  days' 
journey  inland  from  the  latter  place), — I  have  been  led  to  the  conclusion,  not  only  that 
the  Society's  animals  differ  from  that  of  BafFon,  but  also  that  those  of  MM.  Lichtenstein 
and  Riippell  are  sufficiently  distinct  from  both  to  be  regarded  as  a  different  race. 
Whether  the  variations  which  I  am  about  to  point  out  may  be  considered  important 
enough  to  constitute  of  these  animals  three  distinct  species  ;  or  whether  they  may  be 
regarded  as  indicative  only  of  the  existence  of  so  many  local  races  in  one  and  the  same 
species, — may  possibly  remain  a  question,  until  we  can  have  the  opportunity  of  consulting 
Senegalese  specimens  of  the  Nanguer,  which  appears  no  longer  to  exist  in  any  European 
Museum,  together  with  specimens,  if  any  such  should  be  found,  of  similar  animals  from 
intermediate  localities.  At  present  I  am  disposed  to  consider  them  as  three  species,  to 
be  provisionally  adopted  (like  those  which  have  been  formed  from  animals  intimately 
allied  to  the  Gazelle,  Antilope  Boreas,  Pall.)  until  further  investigation  shall  lead  to  a 
more  perfect  understanding  of  the  subject.  With  the  view  of  furnishing  the  means  of 
comparison  between  the  Society's  animals,  which  were  transmitted  under  the  native 
name  of  M'horr  and  those  published  by  other  authors,  I  proceed  to  give  a  detailed  de- 
scription of  the  former,  taken  chiefly  from  the  individual  which  has  lately  died  at  the 
Society's  Gardens,  and  which,  except  in  one  or  two  trifling  particulars  to  be  hereafter 
noticed,  agrees  in  all  respects  with  that  which  still  survives. 
The  form  of  the  Mliorr  is  light  and  elegant ;  its  neck  is  long  and  slender ;  its  tail  is 
of  moderate  length ;  its  limbs  are  extremely  slender  and  delicate ;  and  its  hoofs  are 
short,  pointed,  and  form  a  rather  acute  angle  at  their  anterior  margin.  The  head  tapers 
uniformly,  with  a  face  moderately  prolonged,  suborbital  sinuses  of  small  extent,  and  its
