  Description. 
  — 
  Length 
  5-25 
  mm., 
  width 
  including 
  setae 
  1-4 
  mm. 
  

   Segments 
  36-84. 
  Body 
  small, 
  elongate, 
  nearly 
  linear, 
  flattened 
  

   dorsoventrally; 
  fragments 
  easily. 
  Lateral 
  ventral 
  surface 
  and 
  ventral 
  

   sides 
  of 
  parapodial 
  lobes 
  thickly 
  set 
  with 
  small, 
  globular 
  to 
  elongate 
  

   papillae, 
  usually 
  covered 
  with 
  debris. 
  Prostomium 
  small, 
  oval; 
  

   anterior 
  and 
  posterior 
  pairs 
  of 
  eyes 
  closely 
  approximated. 
  Single 
  

   median 
  antenna 
  short, 
  subulate 
  (lateral 
  antennae 
  lacking). 
  Ten- 
  

   tacular 
  segment 
  achaetous; 
  tentacular 
  cirri 
  similar 
  to 
  median 
  antenna. 
  

   A 
  digitiform 
  facial 
  tubercle 
  on 
  a 
  rounded 
  lobe 
  dorsal 
  to 
  the 
  mouth 
  

   and 
  ventral 
  to 
  the 
  prostomium. 
  (On 
  this 
  character, 
  Southern 
  (1914) 
  

   differentiated 
  P. 
  tuberculata; 
  the 
  lobe, 
  on 
  which 
  the 
  facial 
  tubercle 
  is 
  

   located, 
  appears 
  to 
  be 
  retractile; 
  surrounded 
  by 
  the 
  bases 
  of 
  the 
  palps, 
  

   tentacular 
  cirri 
  and 
  median 
  antenna, 
  the 
  facial 
  tubercle 
  is 
  easily 
  

   overlooked 
  unless 
  the 
  region 
  is 
  quite 
  relaxed.) 
  Elytra 
  numerous, 
  on 
  

   segments 
  2, 
  4, 
  5, 
  7, 
  9, 
  11, 
  13, 
  15, 
  17, 
  19, 
  21, 
  23, 
  24, 
  continuing 
  on 
  all 
  

   segments 
  to 
  end 
  of 
  body; 
  elytra 
  nearly 
  cover 
  the 
  dorsum 
  except 
  for 
  a 
  

   narrow 
  middorsal 
  part, 
  usually 
  pressed 
  close 
  to 
  body; 
  elytral 
  surface 
  

   smooth, 
  with 
  few 
  microtubercles, 
  somewhat 
  areolate 
  as 
  seen 
  under 
  

   magnification, 
  posterior 
  border 
  with 
  few 
  scattered 
  papillae, 
  somewhat 
  

   moniliform. 
  Notosetae 
  simple, 
  slender, 
  finely 
  spinous, 
  tapering 
  to 
  

   capillary 
  tips, 
  upper 
  ones 
  shorter, 
  with 
  pronounced 
  angles, 
  the 
  rest 
  

   longer, 
  with 
  more 
  gradual 
  curves. 
  Neurosetae 
  stouter 
  than 
  notosetae, 
  

   compound, 
  with 
  short, 
  falcate 
  terminal 
  pieces. 
  Color: 
  In 
  alcohol: 
  

   Without 
  color 
  or 
  irregularly 
  pigmented 
  greenish 
  gray; 
  elytra 
  trans- 
  

   lucent, 
  colorless, 
  or 
  greenish 
  gray 
  with 
  a 
  light 
  spot 
  over 
  the 
  place 
  of 
  

   attachment, 
  or 
  brownish; 
  often 
  with 
  much 
  debris.
