  antennae 
  springing 
  from 
  underneath 
  the 
  base 
  of 
  the 
  inner, 
  half 
  as 
  long 
  again, 
  

   and 
  slender. 
  Segments 
  of 
  the 
  thorax 
  directed 
  backwards 
  at 
  their 
  postero- 
  

   lateral 
  margins 
  ; 
  first 
  segment 
  broader 
  than 
  others 
  ; 
  succeeding 
  segments 
  

   subequal, 
  each 
  with 
  a 
  flattened 
  granulated 
  ridge 
  on 
  its 
  posterior 
  margin, 
  

   giving 
  the 
  back 
  a 
  transversely 
  grooved 
  appearance. 
  First 
  segment 
  of 
  

   abdomen 
  produced 
  posteriorly 
  into 
  a 
  flattened 
  truncate 
  expansion, 
  with 
  a 
  

   slight 
  median 
  indentation 
  ; 
  last 
  segment 
  placed 
  almost 
  underneath 
  the 
  

   former, 
  triangular 
  in 
  shape, 
  with 
  a 
  pyramidal 
  tubercle 
  on 
  each 
  side, 
  its 
  apex 
  

   united 
  to 
  the 
  internal 
  rami 
  of 
  the 
  caudal 
  lamellae. 
  External 
  rami 
  thick, 
  

   angular, 
  and 
  two-jointed. 
  Legs

  This 
  species 
  is 
  certainly 
  the 
  female 
  of 
  Talorchestia 
  quoyana, 
  and 
  therefore 
  

  

  ought 
  to 
  disappear 
  from 
  the 
  catalogue. 
  I 
  have 
  repeatedly 
  found 
  the 
  two 
  

  

  together, 
  and 
  in 
  fact 
  have 
  seldom 
  collected 
  the 
  one 
  without 
  the 
  other. 
  

  

  The 
  males 
  of 
  the 
  Talitrus, 
  and 
  the 
  females 
  of 
  the 
  Talorchestia, 
  have 
  never 
  

  

  yet 
  been 
  described 
  as 
  such.

   This 
  genus 
  is 
  defined 
  as 
  follows 
  : 
  — 
  " 
  Superior 
  and 
  inferior 
  antennae 
  

   subequal, 
  scarcely 
  longer 
  than 
  the 
  cephalon. 
  The 
  rest 
  of 
  the 
  animal 
  

   generally 
  resembling 
  Allorchestes, 
  except 
  the 
  telson, 
  which 
  is 
  deeply 
  cleft." 
  

  

  It 
  in 
  reahty 
  includes 
  all 
  those 
  Crustaceans 
  which 
  would 
  range 
  under 
  

   Allorchestes, 
  but 
  for 
  the 
  cleft 
  telson.
