  Michaelsen's 
  recent 
  memoir^ 
  above 
  referred 
  to^ 
  on 
  Phreodri- 
  

   lus 
  kerguelenensis, 
  in 
  which 
  he 
  brings 
  forward 
  evidence 
  

   in 
  favour 
  of 
  uniting 
  the 
  genus 
  Hesperodrilus 
  with 
  Phreo- 
  

   drilus; 
  butj 
  curiously 
  enough, 
  the 
  type 
  species, 
  P. 
  subter- 
  

   raneus, 
  presented 
  apparently 
  so 
  totally 
  different 
  a 
  male 
  

   apparatus 
  that 
  it 
  seemed 
  to 
  be 
  of 
  great 
  importance 
  to 
  re- 
  

   examine 
  this 
  form. 
  

  

  I 
  had, 
  as 
  I 
  thought, 
  a 
  specimen 
  of 
  P. 
  subterraneus, 
  col- 
  

   lected 
  by 
  Mr. 
  W. 
  W. 
  Smith, 
  who 
  had 
  furnished 
  Beddard 
  

   with 
  his 
  material. 
  My 
  specimen 
  was 
  labelled 
  "P. 
  subter- 
  

   raneus" 
  by 
  Mr. 
  Smith, 
  who 
  is 
  a 
  keen 
  observer 
  of 
  Oligo- 
  

   chsetes. 
  I 
  therefore 
  proceeded 
  to 
  examine 
  the 
  male 
  apparatus, 
  

   but 
  the 
  result 
  of 
  my 
  investigation 
  differs, 
  in 
  certain 
  points, 
  

   so 
  greatly 
  from 
  Beddard's 
  account 
  of 
  P. 
  subterraneus 
  that 
  

   I 
  am 
  compelled 
  to 
  employ 
  a 
  new 
  name 
  for 
  the 
  worm. 
  As 
  I 
  

   was 
  for 
  the 
  moment 
  interested 
  only 
  in 
  the 
  male 
  apparatus, 
  

   on 
  the 
  assumption 
  that 
  the 
  worm 
  was 
  identical 
  with 
  Bed- 
  

   dard's 
  species, 
  I 
  made 
  but 
  a 
  cursory 
  examination 
  of 
  the 
  

   individual, 
  in 
  order 
  to 
  add 
  any 
  facts 
  that 
  the 
  mature 
  speci- 
  

   men 
  might 
  present, 
  supplementary 
  to 
  those 
  recorded 
  by 
  

   Beddard 
  for 
  his 
  immature 
  individuals. 
  

  

  I 
  propose 
  for 
  this 
  new 
  species 
  the 
  specific 
  name, 
  P. 
  bed- 
  

   dardi, 
  in 
  reference, 
  I 
  need 
  hardly 
  say, 
  to 
  my 
  friend, 
  who 
  has 
  

   done 
  so 
  much 
  to 
  elucidate 
  the 
  Oligochaetal 
  fauna 
  of 
  New 
  

   Zealand. 
  

  

  My 
  specimen 
  measures 
  40 
  mm. 
  by 
  1*25 
  mm. 
  It 
  is 
  thus 
  

   rather 
  shorter 
  than 
  P. 
  subterraneus, 
  specimens 
  of 
  which, 
  

   he 
  says, 
  " 
  measure 
  about 
  2 
  inches." 
  

  

  I 
  counted 
  seventy-eight 
  segments. 
  

  

  The 
  dorsal 
  chaetse 
  visible, 
  as 
  Beddard 
  noted, 
  to 
  the 
  naked 
  

   eye 
  are, 
  like 
  the 
  ventral 
  chaetae, 
  carried 
  on 
  slight 
  promi- 
  

   nences; 
  and 
  the 
  muscles 
  of 
  each 
  bundle 
  are 
  relatively 
  of 
  

   great 
  size, 
  as 
  they 
  spread 
  out 
  so 
  as 
  to 
  extend 
  almost 
  the 
  entire 
  

   length 
  of 
  a 
  segment 
  (PI. 
  14, 
  fig. 
  14). 
  The 
  dorsal 
  chastse 
  com- 
  

   mence 
  in 
  Segment 
  III; 
  they 
  are 
  absent 
  from 
  Segment 
  II, 
  as 
  

   in 
  most 
  other 
  species 
  of 
  this 
  genus. 
  Beddard 
  makes 
  no 
  

   reference 
  to 
  this 
  absence 
  in 
  P. 
  subterraneus, 
  though 
  in 
  a
