  Dr. 
  Hobson, 
  of 
  Tasmania, 
  lias 
  given 
  an 
  admirable 
  description 
  of 
  C. 
  

   anstraUs, 
  which 
  he 
  dissected 
  and 
  described 
  in 
  1840 
  (Tasmanian 
  Journal 
  of 
  

   Natural 
  Science, 
  Vol. 
  I.) 
  This 
  species 
  is 
  near 
  to 
  C. 
  antarcticus 
  in 
  the 
  size 
  

   of 
  its 
  pectorals, 
  etc., 
  but 
  widely 
  different 
  in 
  the 
  shape 
  of 
  its 
  tail. 
  Its 
  length 
  

   is 
  said 
  to 
  be 
  2 
  feet 
  6 
  inches. 
  His 
  whole 
  paper 
  is 
  replete 
  with 
  valuable 
  and 
  

   interesting 
  information 
  relative 
  to 
  the 
  viscera, 
  and 
  other 
  organs 
  and 
  parts 
  

   of 
  this 
  peculiar 
  fish. 
  One 
  short 
  sentence 
  only 
  can 
  I 
  quote: 
  — 
  "The 
  inferior 
  

   extremity 
  is 
  especially 
  interesting 
  from 
  its 
  quadruped-like 
  form; 
  here 
  is, 
  in 
  

   reality, 
  the 
  pelvis 
  of 
  the 
  fish." 
  I 
  quote 
  this 
  the 
  more 
  willingly 
  in 
  hopes 
  

   that 
  some 
  of 
  our 
  young 
  anatomists 
  (to 
  whom 
  that 
  circumstance 
  quoted 
  may 
  

   be 
  unknown), 
  may 
  also 
  be 
  led 
  to 
  dissect 
  and 
  describe 
  other 
  species 
  of 
  this 
  

   curious 
  genus 
  ; 
  seeing, 
  too, 
  that 
  they 
  are 
  not 
  uncommon 
  here 
  on 
  our 
  shores 
  

   during 
  the 
  summer.

  [Read

  1878.] 
  

  

  On 
  the 
  21st 
  January, 
  1878, 
  my 
  attention 
  was 
  called 
  to 
  an 
  unusually 
  large 
  

   caterpillar, 
  apparently 
  asleep 
  on 
  the 
  trunk 
  of 
  an 
  Acacia 
  tree 
  (silver 
  wattle). 
  

   At 
  first 
  sight, 
  it 
  seemed 
  so 
  much 
  like 
  the 
  bark 
  of 
  the 
  tree 
  in 
  hue, 
  that 
  it 
  

   was 
  not 
  readily 
  distinguished 
  from 
  it. 
  The 
  larva 
  was 
  stretched 
  out 
  to 
  

   its 
  full 
  length, 
  nearly 
  3" 
  6'" 
  ; 
  it 
  was 
  elongate, 
  and 
  of 
  the 
  ordinary 
  form, 
  

   pretty 
  evenly 
  cylindrical 
  throughout, 
  though 
  thickest 
  in 
  the 
  middle 
  and 
  

   tapering 
  towards 
  its 
  head 
  and 
  tail, 
  and 
  skin 
  smooth. 
  In 
  colour, 
  it 
  was 
  

   peculiarly 
  mottled 
  or 
  finely 
  speckled 
  (irrorated) 
  with 
  very 
  minute 
  points 
  

   of 
  black, 
  red 
  (carmine), 
  and 
  ash 
  colours 
  — 
  the 
  latter 
  predominating 
  — 
  which, 
  

   combined, 
  and 
  at 
  a 
  Httle 
  distance 
  gave 
  it 
  the 
  colour 
  of 
  the 
  reddish-grey 
  

   bark 
  of 
  the 
  tree 
  above-mentioned. 
  It 
  had 
  two 
  minute 
  bright 
  red 
  (carmine) 
  

   spots 
  close 
  together 
  on 
  its 
  back, 
  near 
  the 
  tail, 
  and 
  when 
  in 
  motion 
  two 
  

   large 
  triangular 
  dark 
  splashes 
  were 
  displayed 
  on 
  its 
  back 
  ; 
  the 
  colour 
  of 
  the 
  

   belly 
  of 
  the 
  larva 
  was 
  pale 
  (dull 
  white), 
  with 
  several 
  round 
  olive 
  spots 
  in 
  

   pairs, 
  corresponding 
  to 
  its 
  belly 
  feet. 
  Its 
  head 
  was 
  small, 
  of 
  a 
  pale 
  ludian- 
  

   yeilow 
  colour 
  ; 
  its 
  hind 
  feet 
  were 
  large, 
  and 
  it 
  had 
  also 
  two 
  broad 
  anal 
  feet.
