  am 
  very 
  much 
  inclined 
  to 
  think 
  that 
  these 
  specimens 
  may- 
  

   be 
  referable 
  to 
  P. 
  dentata 
  of 
  Milne-Edwards, 
  but 
  I 
  have 
  never 
  

   seen 
  either 
  a 
  specimen 
  or 
  a 
  full 
  description 
  of 
  that 
  species, 
  

   and 
  have 
  been 
  consequently 
  compelled 
  to 
  rely 
  upon 
  the 
  

   figure 
  of 
  it 
  on 
  pi. 
  xviii. 
  of 
  Milne-Edwards's 
  Hist. 
  nat. 
  Crust. 
  

   This 
  figure 
  represents 
  the 
  dactyli 
  as 
  not 
  longer 
  than 
  the 
  pro- 
  

   podal 
  segments 
  of 
  the 
  appendages, 
  and 
  the 
  length 
  of 
  each 
  is 
  

   not 
  more 
  than 
  five 
  times 
  as 
  great 
  as 
  the 
  height. 
  

  

  Twelve 
  specimens 
  were 
  obtained, 
  four 
  of 
  which 
  were 
  taken 
  

   on 
  the 
  land 
  at 
  Laudat, 
  at 
  an 
  altitude 
  of 
  about 
  1000 
  feet 
  ; 
  for 
  

   the 
  rest 
  no 
  special 
  locality 
  was 
  mentioned. 
  

  

  The 
  following 
  is, 
  I 
  believe, 
  a 
  complete 
  list 
  of 
  the 
  remaining 
  

   species 
  of 
  the 
  genus 
  Pseudotelphusa 
  :

   pi. 
  xviii. 
  fig. 
  14. 
  — 
  The 
  long 
  and 
  slender 
  dactyli 
  of 
  

   tenuipes 
  serve 
  to 
  separate 
  it 
  from 
  this 
  species. 
  In 
  other 
  

   respects 
  the 
  two 
  seem 
  to 
  be 
  closely 
  allied. 
  

  

  P.

  Kingsley 
  (Proc. 
  Acad. 
  Nat. 
  Sci. 
  

   Phil. 
  1880, 
  p. 
  34) 
  asserts 
  that 
  this 
  species 
  may 
  be 
  recog- 
  

   nized 
  at 
  once 
  by 
  its 
  reflexed 
  front 
  and 
  large 
  antero-lateral 
  

   teeth.
