  It 
  is 
  stated 
  in 
  the 
  Monograph 
  (vol. 
  ii. 
  part 
  i. 
  p.

  that 
  

   this 
  annelid 
  is 
  found 
  from 
  Shetland 
  to 
  the 
  Channel 
  Islands, 
  

   along 
  both 
  shores, 
  and 
  occurring 
  alike 
  in 
  the 
  tidal 
  region 
  and 
  

   in 
  deep 
  water; 
  but 
  only 
  six 
  are 
  found 
  in 
  this 
  collection, 
  three 
  

   being 
  obtained 
  at 
  a 
  depth 
  of 
  10 
  fathoms 
  at 
  Olliberry, 
  Sliet- 
  

   land. 
  They 
  were 
  dredged 
  along

  at 
  a 
  depth 
  of 
  

   96 
  fatiioms. 
  

  

  The 
  largest 
  specimen 
  had 
  89 
  segments, 
  but 
  a 
  specimen 
  

   having 
  130 
  segments 
  is 
  mentioned 
  in

  The

  has 
  

   similar 
  proportions 
  to

  but 
  is

   less.

  The 
  foot 
  differs 
  from 
  that 
  of

  the

  smaller,

  the 
  ventral 
  lameUa 
  is 
  more 
  ovoid 
  

   than 
  pointed. 
  The 
  most 
  diagnostic 
  feature 
  is 
  the 
  presence 
  

   of 
  a 
  prominent 
  papilla 
  below 
  the 
  point 
  of
