  1 
  Huxley 
  (Proc. 
  Zool. 
  Soc. 
  London, 
  1878, 
  p. 
  771) 
  mentions 
  two 
  specimens 
  of 
  a 
  

   Parancplirops 
  in 
  the 
  British 
  ^Museum, 
  said 
  to 
  have 
  come 
  from 
  the 
  Fiji 
  Islands. 
  

   Mr. 
  Edward 
  .1. 
  Miers 
  wrote 
  to 
  me, 
  February 
  4, 
  1894, 
  that 
  he 
  could 
  not 
  find 
  any 
  such 
  

   specimens 
  in 
  the 
  collection 
  of 
  the 
  British 
  Museum. 
  Mr. 
  Charles 
  Chilton, 
  of 
  Christ- 
  

   church, 
  New 
  Zealand, 
  to 
  whom 
  I 
  am 
  indebted 
  for 
  a 
  fine 
  collection 
  of 
  the 
  crayfishes 
  

   of 
  that 
  country, 
  has 
  been 
  at 
  some 
  pains 
  to 
  procure 
  specimens 
  of 
  the 
  fresh-water 
  

   Crustacea 
  of 
  the 
  P'ijis, 
  and 
  he 
  informs 
  me 
  that 
  all 
  the 
  "crayfi.shes" 
  have 
  proved 
  

   to 
  be 
  fresh-water 
  prawns 
  (Palamon). 
  It 
  is 
  probable 
  that 
  the 
  specimens 
  of 
  Para- 
  

   "nephrops 
  labelled 
  " 
  Fiji 
  Islands" 
  in 
  the 
  British 
  Museum 
  were 
  assigned 
  to 
  the 
  wrong 
  

   locality.
