  show 
  the 
  vermiform 
  contents 
  described 
  by 
  him. 
  All 
  the 
  papillae 
  are 
  

   attached 
  to 
  the 
  body 
  in 
  the 
  same 
  way 
  as 
  the 
  dorsal 
  cirri. 
  

  

  The 
  anal 
  segment 
  is 
  without 
  rami 
  or 
  setae, 
  and 
  is 
  smooth 
  above. 
  It 
  

   has, 
  however, 
  two 
  large 
  dorsal 
  cirri, 
  and 
  a 
  median, 
  elongated, 
  cylindri- 
  

   cal 
  ventral 
  cirrus. 
  

  

  The 
  feet 
  are 
  unramous, 
  carry 
  numerous 
  papillae, 
  and 
  often 
  appear 
  to 
  

   be 
  bifurcate 
  at 
  extremity, 
  owing- 
  to 
  one 
  of 
  these 
  papilla? 
  arising 
  near 
  the 
  

   apes 
  and 
  pointing 
  outward, 
  reaching 
  to 
  the 
  apex 
  of 
  the 
  foot. 
  

  

  The 
  setae 
  (fig. 
  GO) 
  are 
  all 
  compound, 
  delicate; 
  those 
  on 
  the 
  anterior 
  

   segments 
  relatively 
  short 
  (figs. 
  C4, 
  65). 
  

  

  The 
  pharynx 
  occupies 
  four 
  segments. 
  The 
  stomach 
  is 
  barrel-shaped, 
  

   transversely 
  striated, 
  occupies 
  four 
  segments. 
  The 
  iatestine 
  in 
  the 
  first 
  

   segment 
  back 
  of 
  the 
  stomach 
  is 
  very 
  narrow 
  ; 
  just 
  back 
  of 
  this 
  the 
  in- 
  

   testine 
  becomes 
  quite 
  large. 
  

  

  Some 
  specimens 
  had 
  the 
  body 
  cavity 
  filled 
  with 
  a 
  granular 
  fluid 
  

   without 
  corpuscles 
  of 
  any 
  kind. 
  In 
  others 
  there 
  were 
  numerous 
  cor- 
  

   puscles, 
  in 
  form 
  similar 
  to 
  those 
  found 
  in 
  Cirratulus, 
  reddish 
  purple, 
  with 
  

   'clear 
  center, 
  their 
  diameter 
  about 
  one-fifth 
  that 
  of 
  the 
  body. 
  They 
  

   floated 
  about 
  freely, 
  rolling 
  over 
  each 
  other. 
  They 
  were 
  all 
  back 
  of 
  the 
  

   stomach. 
  In 
  one 
  large 
  specimen 
  there 
  were 
  70 
  of 
  these 
  corpuscles. 
  In 
  

   other 
  specimens 
  the 
  place 
  of 
  these 
  corpuscles 
  was 
  taken 
  by 
  cells, 
  which 
  

   seemed 
  to 
  be 
  simply 
  membranous 
  sacks 
  with 
  fluid 
  contents. 
  Some 
  of 
  

   these 
  were 
  quite 
  large, 
  others 
  small. 
  They 
  were 
  spherical, 
  or 
  somewhat 
  

   elongated. 
  In 
  number 
  and 
  position 
  they 
  agreed 
  with 
  the 
  purple 
  disks 
  

   mentioned 
  above. 
  When 
  the 
  purple 
  disks 
  existed 
  the 
  cirri 
  and 
  papillae 
  

   were 
  filled 
  with 
  dark-brown, 
  almost 
  black, 
  pigment. 
  This 
  was 
  also 
  

   sometimes 
  the 
  case, 
  but 
  always 
  in 
  a 
  less 
  degree, 
  when 
  the 
  purple 
  disks 
  

   were 
  absent. 
  

   The 
  diameter 
  was 
  greatest 
  at 
  the 
  middle 
  of 
  the 
  body. 
  

   Dorsum, 
  yellowish-white; 
  sides 
  and 
  feet, 
  white. 
  

   Length, 
  3-4 
  mm 
  . 
  

   Diameter, 
  0.0-0.8""". 
  

  

  This 
  form 
  occurred 
  in 
  nearly 
  all 
  dredging, 
  appearing 
  to 
  be 
  very 
  gen- 
  

   erally 
  distributed.
