  List 
  of 
  specimens 
  examined 
  : 
  

  

  Near 
  Dunedin 
  (South 
  Island), 
  ten 
  males, 
  thirteen 
  females 
  (Colls. 
  

   Mus, 
  Comp. 
  Zool. 
  and 
  Coll. 
  Dunedin 
  Mus.); 
  Oamaru 
  (South 
  Island), 
  

   one 
  male 
  (Coll. 
  Dunedin 
  Mus.). 
  

  

  According 
  to 
  Chilton,- 
  P. 
  zealandicus 
  has 
  been 
  found 
  in 
  the 
  western 
  

   tributaries 
  of 
  the 
  Waiau 
  (in 
  the 
  southwestern 
  part 
  of 
  Otago) 
  and 
  in 
  

   Stewart 
  Island. 
  

  

  Of 
  a 
  series 
  of 
  specimens 
  collected 
  in 
  a 
  small 
  valley 
  at 
  Sawyer's 
  Bay, 
  

   near 
  Dunedin, 
  sent 
  to 
  me 
  by 
  Mr. 
  Charles 
  Chilton, 
  some 
  were 
  taken 
  

   from 
  small 
  streams 
  affording 
  a 
  small 
  tiow 
  of 
  water, 
  while 
  others 
  were 
  

   captured 
  in 
  a 
  little 
  reservoir, 
  not 
  more 
  than 
  ten 
  feet 
  deep, 
  formed 
  by 
  

   damming 
  up 
  one 
  of 
  the 
  small 
  streams. 
  The 
  maximum 
  length 
  attained 
  

   by 
  the 
  individuals 
  inhabiting 
  the 
  streams 
  is 
  about 
  81 
  mm. 
  These 
  

   specimens 
  are 
  sexually 
  mature, 
  as 
  is 
  shown 
  by 
  the 
  fact 
  that 
  some 
  of 
  the 
  

   females 
  carry 
  young 
  beneath 
  the 
  abdomen. 
  In 
  all 
  these 
  examples 
  from 
  

   the 
  small 
  streams 
  the 
  carapace 
  is 
  well-nigh 
  destitute 
  of 
  spines 
  and 
  

   tubercles. 
  The 
  specimens 
  from 
  the 
  reservoir, 
  on 
  the 
  contrary, 
  are 
  all 
  

   very 
  large, 
  attaining 
  a 
  length 
  of 
  118 
  to 
  158 
  mm., 
  and 
  heavily 
  tuber- 
  

   culated 
  on 
  the 
  sides 
  of 
  the 
  carapace, 
  the 
  tubercles 
  having 
  the 
  form 
  of 
  

   prominent, 
  smooth, 
  rounded 
  papill*.
