MR.  E.  T.  BENNETT'S  ACCOUNT  OF  MACROPUS  PARRYI. 
continuous  with  that  of  the  belly  and  pouch ;  and  on  the  hinder  part  of  the  haunches 
on  either  side  (or  rather  on  a  space  bounded  by  the  base  of  the  tail,  the  prymna,  and 
the  marsupium,)  is  a  broad  patch  of  light  yellowish  brown.  In  the  common  species  the 
hair  of  the  tail  is  far  less  bristly,  longer,  softer,  and  by  no  means  adpressed. 
The  head  above  is  of  a  greyish  mouse  colour,  more  intense  from  the  eyes  forwards, 
where  it  becomes  almost  wholly  of  a  dusky  black.  Bordering  this  darker  colour  below, 
on  a  level  with  the  lower  eyelid,  a  broad  well-defined  white  band  extends  along  the 
cheek  from  the  posterior  angle  of  the  eye  to  the  angle  of  the  mouth.  Below  this  is  a 
similar  but  less  strongly  marked  band  of  the  common  grey  colour,  which  passes  from 
the  back  and  sides  of  the  neck  over  the  sides  of  the  head,  and  is  continued  along  the 
last-mentioned  band  to  the  angle  of  the  mouth.  The  lips  are  grey,  with  an  admixture 
of  long  black  and  white  bristly  hairs,  and  the  latter  are  especially  remarkable  on  the 
lower  lip  and  chin.  A  broad  whitish  patch,  with  httle  of  the  grey  mixture,  occupies 
a  space  bounded  by  the  edges  of  the  lower  jaw  and  extending  to  the  upper  part  of  the 
throat.  The  ears  are  mouse-coloured  at  the  base,  with  a  light  grey  patch  on  the  vertex 
between  them,  grey  in  the  middle,  and  dusky  at  their  tips.  Externally  they  are  very 
thinly  clothed  with  short  scattered  hairs,  and  internally  they  are  almost  naked,  excepting 
a  slight  tuft  of  white  hairs  at  the  base  of  their  anterior  margin,  and  a  narrow  edging  all 
round  of  short  whitish  hairs.  This  extreme  thinness  of  the  clothing  of  the  ears  renders 
visible  on  their  inner  surface,  and  also  by  transmitted  light,  a  number  of  small  glan- 
dular transparent  pores.  In  the  common  species  these  organs  are  thickly  clothed  with 
hair  on  their  outer  surface,  and  are  much  less  bare  internally  than  in  the  animal  brought 
home  by  Sir  Edward  Parry,  and  there  are  consequently  no  transparent  pores  visible  in 
them :  the  hairs  of  the  margin  of  the  ears  are  also,  in  the  common  species,  of  a  dark 
brown  approaching  to  black. 
On  the  limbs  the  hairs  become  gradually  shorter  and  more  rigid.  The  whole  of  the 
fore  paw  is  black,  with  a  slight  admixture  of  grey  on  the  metacarpal  and  carpal  regions; 
and  the  claws  also  are  black.  On  the  hinder  feet  the  two  large  outer  toes  are  deep 
black,  and  covered  with  long  rigid  hairs  as  far  as  the  base  of  the  strong  black  hoof-like 
claws.    The  two  small  united  toes  are  light  grey;  like  the  metatarsus  and  tarsus. 
The  comparative  extent  of  the  naked  muzzle  appears  in  this  group,  as  in  various 
tribes  of  Ruminants,  to  afford  an  excellent  guide  in  the  discrimination  of  species,  and 
perhaps  also  of  sections,  without  attaining,  as  in  some  other  cases,  a  value  of  generic 
importance.  In  the  species  under  consideration  it  occupies  the  whole  space  between 
the  nostrils,  and  downwards  to  the  fissure  of  the  upper  lip,  spreading  over  the  flattened 
extremity  of  the  nose,  and  giving  ofif  on  either  side  a  rather  broad  margin  to  the  upper 
edge  of  each  nostril.  It  is  covered  with  rather  large  and  conspicuous  papillcs.  In  this 
respect  the  animal  is  alhed  to  the  Bush  Kangaroo,  Macr.  Ualabatus,  Less. ;  and  differs 
altogether  from  the  common  Kangaroo,  in  which  the  naked  muzzle  is  limited  to  a  narrow 
margin  surrounding  each  of  the  nostrils,  with  a  very  slight  band  of  connexion  in  front.
