  Collected

  Presented 
  by 
  the 
  Sara- 
  

   wak 
  Museum. 
  Five 
  specimens 
  examined. 
  

  

  This 
  would 
  seem 
  to 
  be 
  a 
  larger 
  pale-bellied 
  form 
  of 
  the 
  

   Kina-Balu 
  E. 
  whitehead!, 
  a 
  species 
  which, 
  curiously 
  enough, 
  

   has 
  not 
  as 
  yet 
  turned 
  up 
  in 
  the 
  intermediate 
  region 
  of 
  Baram, 
  

   so 
  well 
  worked 
  by 
  Messrs. 
  Hose 
  and 
  Everett. 
  

  

  I 
  owe 
  the 
  opportunity 
  of 
  describing 
  this

  the 
  kindness 
  

   of 
  Mr.

  C. 
  Moulton,

  Sarawak 
  Museum, 
  who 
  has 
  sent 
  

   to 
  the 
  British 
  Museum 
  a 
  small 
  collection 
  of 
  Muridee 
  from 
  

   Balangean 
  for 
  determination.
