  According 
  to 
  Caiman's 
  revision, 
  based 
  on 
  Slater's 
  type 
  specimen 
  of 
  

   Parazetes 
  auchenicus^ 
  and 
  Hoek's 
  Challenger 
  types 
  of 
  A. 
  ramutus^ 
  

   these 
  specimens 
  represent 
  the 
  same 
  species. 
  Accordingly, 
  its 
  range 
  

   is 
  from 
  Japanese 
  waters 
  to 
  Port 
  Philip, 
  on 
  the 
  southern 
  coast 
  of 
  Aus- 
  

   tralia.

  Lou's 
  variety 
  tsingtaoensis 
  of 
  this 
  species 
  is 
  based 
  on 
  the 
  following 
  

   differences 
  between 
  his 
  specimens 
  from 
  the 
  China 
  coast 
  and 
  the 
  earlier 
  

   descriptions 
  of 
  Bohm 
  and 
  Ortmann 
  : 
  The 
  proboscis 
  of 
  A. 
  ramipes 
  is 
  

   half 
  as 
  long 
  as 
  the 
  trunk, 
  whereas 
  in 
  Lou's 
  specimens 
  it 
  is 
  less 
  than 
  

   half 
  as 
  long, 
  and 
  likewise 
  the 
  abdomen 
  is 
  shorter 
  than 
  the 
  proboscis 
  

   in 
  the 
  variety 
  instead 
  of 
  equal 
  to 
  it. 
  The 
  variety 
  has 
  a 
  pair 
  of 
  small 
  

   protuberances 
  behind 
  the 
  base 
  of 
  the 
  chelifores 
  which 
  were 
  not 
  

   described 
  for 
  the 
  species. 
  

  

  With 
  the 
  exception 
  of 
  a 
  somewhat 
  longer 
  abdomen 
  than 
  Lou's 
  fig- 
  

   ures, 
  these 
  Japanese 
  specimens 
  agree 
  so 
  closely 
  with 
  his 
  description 
  

   that 
  I 
  do 
  not 
  believe 
  a 
  separate 
  variety 
  name 
  is 
  tenable. 
  The 
  small 
  

   tubercles 
  at 
  the 
  base 
  of 
  the 
  chelifores 
  are 
  present, 
  and 
  the 
  proboscis 
  is 
  

   less 
  than 
  half 
  as 
  long 
  as 
  the 
  trunk.

  This 
  handsome 
  species 
  is 
  the 
  most 
  easily 
  identified 
  of 
  the 
  Japanese 
  

   species 
  of 
  Ascorhynchus. 
  It 
  bears 
  a 
  superficial 
  resemblance 
  to 
  the 
  

   large 
  Ascorhynchus 
  of 
  the 
  Atlantic, 
  A. 
  armatus 
  (Wilson), 
  but 
  it 
  is 
  

   much 
  coarser 
  in 
  structure 
  than 
  the 
  Atlantic 
  species 
  ; 
  the 
  dorsal 
  trunk 
  

   tubercles 
  are 
  heavier 
  and 
  the 
  proboscis 
  is 
  much 
  stockier 
  and 
  blunter 
  

   than 
  in 
  A. 
  armatus. 
  The 
  collection 
  of 
  an 
  ovigerous 
  male 
  is 
  of 
  interest, 
  

   inasmuch 
  as 
  ovigerous 
  males 
  of 
  the 
  Atlantic 
  species 
  are 
  unknown. 
  

   Tlie 
  eggs 
  are 
  small, 
  packed 
  in 
  a 
  dense 
  saclike 
  mass 
  which, 
  in 
  the 
  pre- 
  

   served 
  state, 
  is 
  draped 
  over 
  the 
  oviger.
