  membrane 
  which 
  forms 
  the 
  wall 
  of 
  the 
  funnel 
  ; 
  in 
  connexion 
  

   with 
  this 
  the 
  figures 
  which 
  Lyman 
  has 
  given 
  * 
  of 
  the 
  dorsal 
  

   spines 
  of 
  several 
  species 
  of 
  Ophiothrix 
  may 
  be 
  consulted. 
  In 
  

   the 
  arms 
  the 
  agreement 
  with 
  Ophiothrix 
  lies 
  in 
  the 
  form 
  of 
  

   the 
  ventral 
  and 
  dorsal 
  scutes, 
  the 
  singleness 
  of 
  the 
  tentacular 
  

   scales, 
  the 
  glassy 
  texture 
  of 
  the 
  divergent 
  spines, 
  of 
  which 
  

   the 
  single 
  (free) 
  spine, 
  as 
  in 
  Ophiothrix, 
  is 
  spinulose 
  on 
  the 
  

   sides 
  and 
  at 
  the 
  apex, 
  and, 
  lastly, 
  in 
  possession 
  of 
  the 
  hooks, 
  

   which 
  are 
  also 
  present 
  in 
  Ophiothrix. 
  

  

  Finally, 
  attention 
  may 
  be 
  called 
  to 
  the 
  resemblance 
  which 
  

   the 
  fin-formation 
  in 
  Ophiopteron 
  presents 
  to 
  that 
  of 
  the 
  

   Pterasteridas. 
  As 
  in 
  those 
  starfishes, 
  it 
  is 
  precisely 
  the 
  lateral 
  

   scutes 
  which 
  are 
  homologous 
  with 
  the 
  adambulacral 
  plates, 
  

   the 
  spines 
  of 
  which 
  in 
  the 
  Ophiuran 
  before 
  us 
  become 
  united 
  

   by 
  a 
  swimming-membrane 
  to 
  form 
  a 
  fin.

  The

  descriptions 
  are 
  the 
  result 
  of 
  an 
  examination 
  

   of 
  the 
  collection 
  of 
  Oriental 
  Cicadida? 
  in 
  the 
  Leyden 
  Museum, 
  

   for 
  which 
  I 
  am 
  indebted 
  to 
  the 
  kindness 
  of 
  Dr. 
  Ritsema, 
  of 
  

   a 
  small 
  but 
  extraordinary 
  novel 
  collection 
  made 
  in 
  Karwar 
  

   and 
  forwarded 
  to 
  me 
  by 
  E. 
  T. 
  Atkinson, 
  Esq., 
  and 
  of 
  another 
  

   small 
  collection 
  received 
  from 
  the 
  southern 
  slopes 
  of 
  the 
  

   Nilgiris 
  and 
  made 
  by 
  my 
  ever 
  helpful 
  friend 
  Gr. 
  F. 
  Hampson, 
  

   Esq. 
  All 
  these 
  species 
  will 
  be 
  subsequently 
  figured.
