  perfect 
  spermatophore 
  buried 
  in 
  a 
  mass 
  of 
  thick 
  mucus, 
  

   out 
  of 
  which 
  it 
  vvas 
  difficult 
  and 
  took 
  a 
  long 
  time 
  to 
  ciear, 
  

   using 
  a 
  fine 
  brush 
  and 
  needle-point. 
  In 
  doing 
  this 
  it 
  is 
  

   impossible 
  to 
  avoid 
  breaking 
  off 
  luauy 
  of 
  the 
  delicate 
  spines. 
  

   The 
  spermatophore 
  is 
  not 
  alvvaN's 
  thus 
  enclosed 
  in 
  mucus, 
  

   and 
  may 
  be 
  found 
  perfectly 
  free 
  and 
  floating 
  in 
  a 
  clear 
  

   liquid. 
  Th6 
  capsule 
  of 
  this 
  specimen 
  is 
  moderately 
  long 
  

   and 
  cylindrical, 
  the 
  flume 
  a 
  little 
  more 
  than 
  1^ 
  times 
  as 
  

   long, 
  ittteuuute 
  at 
  the 
  vas 
  deferens 
  end, 
  having 
  a 
  shorter 
  

   terminal 
  end 
  branching 
  off 
  below. 
  

  

  The 
  sprigs, 
  as 
  they 
  may 
  be 
  termed, 
  carrying 
  spines 
  are 
  

   very 
  numerous 
  on 
  one 
  side 
  of 
  the 
  flume, 
  thirty 
  in 
  numtjer; 
  

   on 
  the 
  opposite 
  side 
  there 
  are 
  only 
  four, 
  situated 
  cluse 
  to 
  

   the 
  capsule

  The 
  general 
  form 
  and 
  proportion 
  of 
  its 
  dift'erent 
  parts 
  

   differ 
  in 
  detail 
  from 
  those 
  I 
  have 
  found 
  and 
  described 
  in 
  

   other 
  species 
  of 
  this 
  genus. 
  The 
  sprigs 
  are 
  set 
  very 
  close 
  

   together 
  on 
  rather 
  elongate 
  substantial 
  stems, 
  and

  are

  The 
  radula 
  is 
  peculiar; 
  the 
  marginals 
  ar'- 
  short, 
  slightly

  unevenly

  the

  Mr. 
  Burnup, 
  in 
  sending 
  this 
  species, 
  says 
  : 
  — 
  '• 
  This 
  species 
  

   has 
  never 
  been 
  described 
  (at 
  least 
  no 
  description 
  of 
  the 
  

   form 
  has 
  been 
  published, 
  though 
  I 
  believe 
  Melvill 
  and 
  Pon- 
  

   sonby 
  have 
  it 
  iu 
  MS., 
  but 
  are 
  keeping 
  it 
  back). 
  It 
  has 
  at 
  

   difi'erent 
  times 
  been 
  identified 
  as 
  H.ph<sdimus 
  and 
  as 
  leuco- 
  

   suiia 
  ; 
  but 
  1 
  tliiuk 
  it 
  is 
  quite 
  distinct 
  from 
  tliese 
  specits."
