  This 
  paper 
  was 
  already 
  in 
  type 
  when 
  I 
  received, 
  by 
  the 
  

   kindness 
  of 
  Prof. 
  Dr. 
  W. 
  Michaelsen, 
  his 
  monograph 
  " 
  Die 
  

   Oligochatenfaunadervorderindisch-ceylonischen 
  Region" 
  (13), 
  

   issued 
  in 
  September, 
  1910. 
  In 
  the 
  following 
  pages 
  is 
  found 
  

   a 
  description 
  of 
  Glyphidrilus 
  annandalei, 
  Mich., 
  which 
  I 
  

   wrote 
  before 
  receiving 
  this 
  monograph. 
  My 
  description 
  agrees 
  

   with 
  that 
  of 
  Michaelsen 
  ; 
  the 
  two 
  descriptions 
  supplement 
  

   each 
  other.

  Length 
  85 
  mm.,

   3 
  mm.;

  of

  98. 
  

  

  Colour 
  uniformly 
  lilac-grey. 
  

  

  Head 
  prolobous; 
  body 
  cylindrical, 
  slightly 
  reduced 
  in 
  

   diameter 
  at 
  the 
  tail. 
  

  

  Setae 
  strictly 
  paired 
  : 
  aa 
  = 
  bc; 
  dd 
  a 
  little 
  larger 
  than 
  half 
  

   the 
  circumference 
  of 
  the 
  body. 
  

  

  Dorsal 
  pores 
  not 
  seen. 
  Clitellum 
  not 
  developed. 
  Nephri- 
  

   dial 
  pores 
  from 
  the 
  third 
  segment, 
  on 
  the 
  anterior 
  margin, 
  in 
  

   the 
  lines 
  of 
  the 
  superior 
  dorsal 
  setae 
  (d). 
  

  

  At 
  the 
  intersegmental 
  furrow 
  x.-xi., 
  a 
  little 
  laterally 
  to 
  the 
  

   lines 
  of 
  ventral 
  bundles 
  of 
  seta?, 
  is 
  present 
  a 
  pair 
  of 
  small 
  

   conical 
  tubercles, 
  contained 
  in 
  two 
  small 
  and 
  not 
  very 
  deep 
  

   pouches 
  ; 
  these 
  tubercles 
  are 
  in 
  relation 
  with 
  the 
  male 
  pores, 
  

   but 
  1 
  have 
  not 
  been 
  able 
  to 
  determine 
  whether 
  the 
  pores 
  are 
  at 
  

   the 
  summit 
  or 
  at 
  the 
  base 
  of 
  the 
  tubercles 
  (PI. 
  XIII. 
  tig. 
  1). 
  

   The 
  tubercles 
  correspond 
  in 
  shape 
  with 
  those 
  drawn 
  by 
  

   Michaelsen 
  (12,

  Female

  Spermathecal

  Four 
  strong 
  gizzards 
  are 
  distributed 
  in 
  segments 
  xiii., 
  xiv., 
  

   xv., 
  and 
  xvi. 
  

  

  The 
  paired 
  hearts 
  are 
  found 
  in 
  segments 
  vi.-ix. 
  At 
  

   x. 
  segment, 
  close 
  behind 
  the 
  anterior 
  septum, 
  a 
  pair 
  of 
  trunks 
  

   originate 
  from 
  the 
  dorsal 
  vessel. 
  These 
  two 
  trunks 
  are 
  

   directed 
  backwards 
  in 
  the 
  ventral 
  region, 
  to 
  unite 
  with 
  the 
  

   subneuial 
  blood-vessel 
  close 
  to 
  the 
  anterior 
  surface 
  of 
  septum
