  Eight 
  specimens 
  (five 
  young). 
  

  

  These 
  two 
  eastern 
  subspecies 
  differ 
  from 
  the 
  other 
  forms 
  

   by 
  their 
  darker 
  colour 
  and 
  tendency 
  to 
  be 
  blackish 
  or 
  dark 
  

   greyish' 
  on 
  the 
  rump, 
  From 
  each 
  other 
  they 
  differ 
  very 
  

   much 
  as 
  do 
  chinensis 
  and 
  belangeri, 
  and, 
  in 
  fact, 
  they 
  may 
  be 
  

   looked 
  upon 
  as 
  eastern 
  representatives 
  of 
  these 
  subspecies 
  

   respectively, 
  yunalis 
  of 
  the 
  olive^grey 
  chinensis 
  and 
  laotum 
  

   of 
  the 
  more 
  fulvous 
  belangeri^ 
  each 
  pair 
  being 
  in 
  about 
  the 
  

   same 
  latitude. 
  

  

  As 
  Dr. 
  Lyon 
  has 
  carefully 
  recorded 
  where 
  the 
  types 
  of 
  all 
  the 
  

   various 
  forms 
  of 
  the 
  Tupaiidai 
  are 
  preserved, 
  I 
  may 
  take 
  this 
  

   opportunity 
  of 
  mentioning 
  that 
  the 
  typical 
  specimens 
  of 
  Tupaia 
  

   lacernata 
  v)ilhinsoni, 
  ohscura, 
  and 
  longicauda, 
  and 
  T. 
  ferru-, 
  

   ginea 
  penangensis, 
  described 
  by 
  Messrs. 
  Robinson 
  and 
  Kloss, 
  

   and 
  hitherto 
  in 
  Selangor, 
  have 
  now 
  been 
  transferred 
  to 
  the 
  

   British 
  Museum, 
  in 
  accordance 
  with 
  the 
  enligh.tened 
  policy 
  

   pursued 
  by 
  the 
  authorities 
  of 
  the 
  Federated 
  Malay 
  States 
  

   Museum 
  in 
  regard 
  to 
  the 
  preservation 
  of 
  types. 
  In 
  a 
  

   temperate 
  climate 
  like 
  that 
  of 
  England 
  types 
  do 
  not 
  dete^ 
  

   riorate 
  in 
  the 
  same 
  way 
  as, 
  however 
  well 
  taken 
  carq 
  of, 
  they 
  

   do 
  in 
  a 
  tropical 
  one.
