  In 
  1861 
  Keferstein 
  and 
  Ehlers 
  described 
  a 
  peculiar 
  Diphyid, 
  

   Diphyes 
  ovata, 
  taken 
  in 
  the 
  Straits 
  of 
  Messina, 
  in 
  which 
  the 
  posterior 
  

   as 
  well 
  as 
  the 
  anterior 
  nectophore 
  had 
  a 
  well-developed 
  somatocyst, 
  

   as 
  in 
  the 
  Prayids, 
  although 
  the 
  two 
  bells 
  were 
  of 
  different 
  outlines 
  

   and 
  one 
  superposed 
  upon 
  the 
  other, 
  as 
  is 
  the 
  case 
  in 
  all 
  Diphyids. 
  

   Chun 
  (1897&) 
  has 
  suggested 
  that 
  D. 
  ovata 
  is 
  actually 
  intermediate 
  

   between 
  the 
  two 
  groups, 
  but 
  since 
  no 
  one 
  since 
  1861 
  has 
  seen 
  a 
  

   siphonophore 
  answering 
  to 
  the 
  original 
  account 
  of 
  D. 
  ovata, 
  it 
  has 
  

   remained 
  a 
  more 
  or 
  less 
  problematical 
  form. 
  For 
  this 
  reason 
  I 
  

   thought 
  it 
  wisest 
  not 
  to 
  lay 
  much 
  stress 
  upon 
  it 
  in 
  my 
  discussion 
  of 
  

   the 
  relationships 
  and 
  classification 
  of 
  the 
  Calycophorae 
  (1911&, 
  p. 
  179). 
  

  

  It 
  is 
  now 
  my 
  good 
  fortune 
  to 
  announce 
  the 
  discovery 
  of 
  three 
  com- 
  

   plete 
  specimens 
  and 
  a 
  loose 
  posterior 
  nectophore 
  which 
  agree 
  with 
  

   the 
  account 
  of 
  Keferstein 
  and 
  Ehlers 
  in 
  all 
  their 
  main 
  features. 
  The 
  

   most 
  interesting 
  feature 
  of 
  the 
  animal 
  is, 
  of 
  course, 
  the 
  fact 
  that 
  the 
  

   posterior 
  nectophore 
  has 
  a 
  well-developed 
  somatocyst, 
  and 
  the 
  mate- 
  

   rial 
  is 
  in 
  good 
  enough 
  condition 
  to 
  allow 
  this 
  statement 
  to 
  be 
  made 
  

   wdthout 
  hesitation. 
  In 
  this 
  it 
  differs 
  from 
  all 
  Diphyids, 
  for 
  though 
  

   Chun 
  (1897&) 
  states 
  that 
  he 
  was 
  able 
  to 
  distmguish 
  the 
  rudiments 
  of 
  

   a 
  somatocyst 
  in 
  all 
  the 
  posterior 
  bells 
  of 
  Galeolaria 
  studied 
  by 
  Mm, 
  

   there 
  is 
  good 
  reason 
  to 
  believe 
  that 
  what 
  he 
  saw 
  was 
  a 
  part 
  of 
  the 
  

   common 
  muscular 
  lamella 
  to 
  which 
  both 
  the 
  nectophores 
  are 
  attached, 
  

   or 
  the 
  dorsal 
  extension 
  of 
  the 
  pedicular 
  canal 
  beyond 
  the 
  point 
  at 
  

   which 
  it 
  joins 
  the 
  lamella 
  (pi. 
  5, 
  fig. 
  6). 
  This 
  prolongation 
  of 
  the 
  

   canal 
  is 
  likewise 
  to 
  be 
  seen 
  in 
  the 
  anterior 
  nectophore, 
  in 
  which 
  the 
  

   somatocyst 
  arises 
  from 
  it. 
  But 
  there 
  is 
  no 
  trace 
  of 
  anything 
  corre- 
  

   sponding 
  to 
  a 
  somatocyst 
  in 
  any 
  of 
  the 
  many 
  posterior 
  bells 
  of
