  Mr. 
  Green's 
  description, 
  omitting 
  figure 
  references, 
  is 
  as 
  follows 
  : 
  — 
  

  

  " 
  Test 
  of 
  adult 
  female 
  irregularly 
  oval, 
  the 
  posterior 
  extremity 
  (in 
  fully 
  matured 
  

   examples) 
  produced 
  into 
  a 
  short 
  upturned 
  tube. 
  In 
  earlier 
  examples 
  this 
  caudal 
  

   extension 
  is 
  in 
  the 
  form 
  of 
  a 
  trough, 
  partially 
  closed 
  above 
  by 
  stout 
  curling 
  filaments. 
  

   Dorsum 
  strongly 
  convex, 
  the 
  sides 
  sloping 
  inwards 
  to 
  the 
  comparatively 
  narrow 
  

   ventral 
  area, 
  which 
  is 
  thin 
  and 
  easily 
  ruptured. 
  Dorsum 
  with 
  three 
  prominent 
  

   transverse 
  waxy 
  ridges 
  produced, 
  at 
  the 
  middle 
  and 
  two 
  sides, 
  into 
  stout 
  pointed 
  

   processes 
  ; 
  the 
  lateral 
  processes 
  longest, 
  tapering 
  to 
  fine 
  points, 
  and 
  projecting 
  (in 
  

   fresh 
  examples) 
  considerably 
  beyond 
  the 
  margin, 
  which 
  is 
  itself 
  thickened 
  and 
  

   tubercular. 
  Posterior 
  margin 
  with 
  two 
  or 
  more 
  tapering 
  processes 
  directed 
  

   backwards. 
  There 
  are 
  several 
  pairs 
  of 
  short 
  white 
  curved 
  filaments 
  on 
  the 
  median 
  

   line, 
  behind 
  the 
  third 
  transverse 
  ridge. 
  In 
  older 
  examples 
  the 
  waxy 
  processes 
  are 
  

   gradually 
  reduced 
  until 
  they 
  practically 
  disappear, 
  and 
  old 
  worn 
  tests 
  are 
  more 
  or 
  

   less 
  globular 
  in 
  form. 
  Colour 
  of 
  early 
  test 
  purplish 
  brown 
  ; 
  the 
  ridges, 
  processes, 
  and 
  

   thickened 
  margins 
  bright 
  coral-red 
  or 
  crimson. 
  Older 
  examples 
  become 
  at 
  first 
  

   uniform 
  pale 
  red, 
  and 
  finally 
  dull 
  reddish 
  brown. 
  There 
  are 
  two 
  white 
  waxy 
  ridges 
  on 
  

   each 
  of 
  the 
  sloping 
  sides, 
  extending 
  from 
  the 
  first 
  and 
  third 
  lateral 
  processes, 
  

   respectively, 
  to 
  the 
  stigmatic 
  openings.

  two 
  prominent 
  transverse

  the

  terminating

  in 
  

   pointed 
  processes. 
  A 
  smaller 
  pointed 
  process, 
  on 
  each
