  is 
  tlie 
  presence 
  of 
  a 
  short 
  acute 
  dorsal 
  keel 
  adjoining 
  the 
  delicate 
  

   terminal 
  spine. 
  It 
  is 
  situated 
  upon 
  tlie 
  centre 
  of 
  the 
  curved 
  hinder 
  

   portion 
  of 
  the 
  shell. 
  The 
  limbs 
  of 
  the 
  snudl 
  inner 
  cone 
  are 
  thread- 
  

   like 
  and 
  quite 
  clo?e 
  to 
  the 
  outer 
  margin. 
  

  

  The 
  name 
  Sepia 
  capensis, 
  according 
  to 
  d'Orbigny, 
  was 
  employed 
  by 
  

   liim 
  in 
  1826, 
  six 
  years 
  before 
  S. 
  audralis 
  was 
  described 
  by 
  Quoy 
  

   and 
  Gaimard. 
  Since, 
  however, 
  no 
  confirmation 
  of 
  that 
  statement 
  could 
  

   be 
  found 
  Dr. 
  Hoyle 
  ' 
  upholds 
  tlie 
  latter 
  name, 
  at 
  the 
  same 
  time 
  

   cbanging 
  the 
  S. 
  australis, 
  founded 
  by 
  d'Orbigny 
  upon 
  an 
  Australian 
  

   form,

  Shell 
  elongate, 
  acutely 
  pointed 
  in 
  front, 
  rounded 
  at 
  the 
  posterior 
  

   end, 
  which 
  is 
  surrounded 
  by 
  a 
  very 
  broad 
  chitinous 
  margin, 
  extending 
  

   along 
  the 
  sides 
  more 
  than 
  half 
  the 
  length 
  of 
  the 
  shell 
  ; 
  the 
  calcareous 
  

   portion 
  is 
  white 
  beneath 
  but 
  pinkish 
  dorsally 
  ; 
  the 
  test 
  is 
  tliin, 
  with 
  

   a 
  narrow 
  ventral 
  groove 
  obliquely 
  striated 
  on 
  each 
  side, 
  then 
  

   longitudinally 
  obtusely 
  ridged, 
  the 
  striae 
  being 
  continued 
  over 
  the 
  

   ridges, 
  forming 
  an 
  angle, 
  and 
  then 
  extending 
  to 
  the 
  chitinous 
  margin, 
  

   but 
  being 
  interrupted 
  posteriorly 
  by 
  tlie 
  limbs 
  of 
  the 
  inner 
  cone. 
  

   These 
  converge 
  to 
  a 
  small 
  rounded 
  end 
  over 
  the 
  moderately 
  deep 
  

   inner 
  cone, 
  where 
  the 
  cross-strite 
  are 
  remarkably 
  conspicuous. 
  The 
  

   dorsal 
  side 
  is 
  curved, 
  obtusely 
  keeled 
  or 
  angled 
  down 
  the 
  middle, 
  and 
  

   besides 
  delicate 
  lines 
  of 
  growth 
  it 
  exhibits 
  a 
  fine 
  wrinkling 
  posteriorly 
  

   and 
  very 
  delicate 
  granulation 
  elsewhere. 
  Tliere 
  is 
  no 
  terminal 
  spine," 
  

   the 
  end 
  being 
  merely 
  a 
  pale 
  rounded 
  boss.

  The 
  two 
  specimens 
  examined 
  agree 
  in 
  every 
  detail, 
  but 
  whether 
  

   tliey 
  are 
  the 
  young 
  stage 
  of 
  a 
  species 
  which 
  attains 
  larger 
  dimensions 
  

   is 
  uncertain. 
  However, 
  the 
  form 
  is 
  so 
  remarkable 
  that 
  I 
  have 
  not 
  

   hesitated 
  to 
  describe 
  it 
  as 
  new.
