  I 
  OWE 
  to 
  the 
  kindness 
  of 
  Mr. 
  B. 
  H. 
  Woodward, 
  of 
  the 
  

   "Western 
  Australian 
  Museum, 
  the 
  opportunity 
  of 
  examining 
  

   the 
  specimens 
  on 
  which 
  the 
  following 
  new 
  subspecies 
  is 
  

   founded 
  : 
  — 
  

  

  Macropus 
  robustus 
  bracteator, 
  subsp. 
  n. 
  

  

  Near 
  M. 
  r. 
  woodwardi, 
  but 
  longer-haired, 
  and 
  browner, 
  

   less 
  rufous. 
  Fur, 
  compared 
  with 
  that 
  of 
  M. 
  r. 
  woodwardi 
  and 
  

   alligatorts, 
  long 
  and 
  thick, 
  as 
  in 
  M. 
  r. 
  cervinus 
  and 
  rubens; 
  

   hairs 
  of 
  nape 
  wholly 
  or 
  partially 
  directed 
  forwards 
  from 
  a 
  

   whorl 
  on 
  the 
  withers. 
  

  

  General 
  colour 
  above 
  pale 
  " 
  mars 
  brown," 
  the 
  hairs 
  u 
  fawn 
  " 
  

   at 
  base 
  with 
  black 
  tips 
  ; 
  the 
  resulting 
  colour 
  not 
  unlike 
  that 
  

   in 
  the 
  shorter-haired 
  alligatoris. 
  Chin 
  brown; 
  rest 
  of 
  middle 
  

   line 
  of 
  under 
  surface 
  creamy 
  white. 
  Head 
  like 
  back. 
  Ectote 
  

   of 
  ear 
  brighter, 
  tending 
  towards 
  russet; 
  long 
  hairs 
  of 
  entote 
  

   white. 
  Limbs 
  whitish, 
  darkening 
  on 
  the 
  hands 
  and 
  feet 
  to 
  

   black 
  on 
  the 
  digits. 
  Tail 
  whitish 
  fawn, 
  not 
  darkening: 
  

   terminally. 
  

  

  Female 
  not 
  essentially 
  different 
  from 
  male. 
  The' 
  head 
  is 
  

   rather 
  greyer 
  ; 
  the 
  ears 
  browner, 
  with 
  a 
  contrasted 
  tuft 
  of 
  

   russet 
  at 
  their 
  anterior 
  base; 
  limbs 
  almost 
  completely 
  white, 
  

   the 
  digits 
  scarcely 
  darker. 
  

  

  Skull 
  very 
  like 
  that 
  of 
  M. 
  r. 
  zooodwardi, 
  but 
  those 
  of 
  all 
  

   the 
  subspecies 
  are 
  very 
  like 
  each 
  other, 
  and 
  I 
  am 
  by 
  no 
  

   means 
  satisfied 
  as 
  to 
  the 
  constancy 
  of 
  the 
  cranial 
  characters 
  

   used 
  by 
  Mr. 
  Schwarz 
  * 
  to 
  separate 
  the 
  different 
  forms. 
  

   The 
  upper 
  profile 
  of 
  the 
  present 
  animal 
  is 
  unusually 
  bowed 
  ; 
  

   nasals 
  convex 
  in 
  both 
  directions 
  ; 
  sides 
  of 
  nasal 
  cavity 
  less 
  

   bowed 
  outwards 
  than 
  in 
  rubens 
  ; 
  coronoid 
  process 
  of 
  medium 
  

   dimensions.
