  Broadway, 
  of 
  the 
  Botanic 
  Station, 
  Scarborongli, 
  

   'J'obago, 
  has 
  recently 
  sent 
  me 
  the 
  skins 
  of 
  two 
  mammals 
  

   representing 
  species 
  one 
  of 
  which 
  is 
  as 
  yet 
  nnrecorded

   that 
  iskind. 
  

  

  UnfortuMiately 
  both 
  of 
  the 
  skins 
  are 
  imperfect, 
  and 
  tlie 
  

   .skulls 
  of 
  both 
  are
