  west

  to 
  Westport 
  aud 
  Greymoutli. 
  Another 
  fact 
  pointing 
  in 
  

   the 
  same 
  direction 
  is 
  found 
  in 
  the 
  distribution 
  of 
  Armadillo 
  speciosus, 
  

   a 
  terrestrial 
  isopod. 
  This 
  is 
  known 
  from 
  the 
  iTorth 
  Island 
  (Bay 
  of 
  

   Islands, 
  Dana, 
  and 
  Wellington, 
  Hiitton), 
  and 
  I 
  have 
  specimens 
  from 
  

   Nelson 
  ; 
  but 
  I 
  have 
  never 
  heard 
  of 
  it 
  occurring 
  in 
  the 
  southern 
  part 
  

   of 
  the 
  South 
  Island." 
  On 
  either 
  side 
  of 
  Cook 
  Strait 
  (Wellington, 
  

   Pelorus 
  Hiver) 
  specimens 
  were 
  found 
  which 
  show 
  a 
  marked 
  api)roach 
  in 
  

   the 
  form 
  of 
  the 
  rostrum, 
  anteunal 
  scale, 
  etc., 
  to 
  P. 
  Zealand 
  icus. 
  

  

  Paranephrops 
  tenuicornls 
  Dana, 
  from 
  fresh-water 
  streams 
  about 
  the 
  

   Bay 
  of 
  Islands, 
  northern 
  Xew 
  Zealand, 
  is 
  described 
  as 
  having 
  a 
  short 
  

   point 
  or 
  tooth 
  on 
  the 
  inner 
  border 
  of 
  the 
  antennal 
  scale, 
  near 
  the 
  apex, 
  

   aud 
  the 
  lower 
  margin 
  of 
  the 
  hand 
  si^inuli-scabrous, 
  but 
  not 
  seriately 
  

   spinous. 
  It 
  is 
  probably 
  tbe 
  same 
  species 
  as 
  P. 
  planifrons.

  In 
  P. 
  zealandicus 
  the 
  chela 
  is 
  much 
  shorter 
  and 
  broader 
  than 
  in 
  

   P. 
  planifrons, 
  and 
  it 
  is 
  furnished 
  with 
  conspicuous 
  dense 
  tufts 
  of 
  silky 
  

   hair, 
  disposed 
  in 
  longitudinal 
  rows. 
  The 
  upper 
  margin 
  of 
  the 
  hand 
  is 
  

   armed 
  with 
  a 
  series 
  of 
  prominent 
  spines, 
  continued 
  as 
  a 
  double 
  row 
  on 
  

   the 
  margin 
  of 
  the 
  dactylus. 
  The 
  lower 
  margin 
  of 
  the 
  hand 
  is 
  furnished 
  

   with 
  a 
  double 
  row 
  of 
  shorter 
  spinous 
  teeth. 
  The 
  outer 
  face 
  of 
  the 
  hand 
  

   is 
  provided 
  with 
  a 
  few 
  tubercles, 
  which 
  seldom 
  develop 
  any 
  spinous 
  

   points; 
  the 
  inner 
  face 
  bears 
  two 
  longitudinal 
  rows 
  of 
  short 
  teeth. 
  

   The 
  rostrum 
  is 
  armed 
  on 
  e 
  ich 
  side 
  with 
  small, 
  blunt 
  teeth, 
  usually 
  five 
  

   in 
  number, 
  but 
  in 
  some 
  individuals 
  three, 
  four, 
  or 
  six; 
  the 
  inferior 
  

   edge 
  is 
  either 
  unarmed 
  or 
  else 
  provided 
  with 
  one 
  or 
  two 
  acute 
  teeth 
  ; 
  a
