  The 
  present 
  paper 
  is 
  the 
  result 
  of 
  the 
  examination 
  of 
  a 
  

   collection 
  belonging 
  to 
  the 
  British 
  Museum 
  and 
  entrusted 
  to 
  

   me 
  by 
  Prof. 
  F. 
  J. 
  Bell, 
  who 
  received 
  them 
  from 
  the 
  Tri- 
  

   vandrum 
  Museum 
  *. 
  

  

  The 
  first 
  work 
  in 
  which 
  Oligochastes 
  from 
  Travancore 
  are 
  

   mentioned 
  is 
  a 
  paper 
  by 
  Miss 
  S. 
  M. 
  Fedarb 
  published 
  in 
  

   1897 
  (4). 
  Prof. 
  Dr. 
  W. 
  Michaelsen 
  has 
  recently 
  discussed 
  

   the 
  drilofauna 
  of 
  the 
  entire 
  Indian 
  Empire 
  and 
  adjacent 
  

   regions 
  in 
  two 
  valuable 
  works 
  (12, 
  13). 
  From 
  these 
  works 
  

   it 
  results 
  that 
  nineteen 
  species 
  of 
  earthworms 
  have 
  already 
  

   been 
  collected 
  in 
  the 
  State 
  of 
  Travancore. 
  

  

  The 
  collection 
  examined 
  by 
  me 
  contains 
  only 
  one 
  of 
  the 
  

   species 
  which 
  are 
  contained 
  in 
  Michaelsen' 
  s 
  lists, 
  viz. 
  Qlyphi- 
  

   drilus 
  annandalei, 
  Mich. 
  It 
  contains 
  besides 
  four 
  new 
  species 
  

   and 
  a 
  " 
  peregrine" 
  species, 
  Lamjnto 
  mauritii, 
  Kinb., 
  which 
  

   lias 
  already 
  been 
  collected 
  in 
  other 
  localities 
  of 
  S. 
  India. 
  

  

  At 
  present 
  our 
  knowledge 
  of 
  the 
  drilofauna 
  of
