  extends 
  from 
  what 
  appears 
  to 
  be 
  a 
  joint 
  in 
  the 
  dorsal 
  wall 
  of 
  

   the 
  capsule 
  to 
  a 
  corresponding 
  joint 
  in 
  the 
  ventral 
  wall 
  of 
  the 
  cap- 
  

   sule. 
  The 
  posterior 
  transverse 
  suture 
  extends 
  from 
  what 
  appears 
  to 
  

   be 
  a 
  joint 
  in 
  the 
  ventral 
  wall 
  of 
  the 
  capsule 
  and 
  runs 
  diagonally 
  

   cephalad 
  to 
  the 
  dorsal 
  wall 
  of 
  the 
  capsule 
  but 
  does 
  not 
  meet 
  a 
  joint. 
  

   The 
  sutures 
  are 
  best 
  seen 
  in 
  a 
  surface 
  view 
  of 
  the 
  capsule. 
  They 
  are 
  

   not 
  superficial 
  grooves, 
  but 
  extend 
  quite 
  deeply 
  into 
  the 
  capsule, 
  

   and 
  are 
  still 
  visible, 
  in 
  part, 
  in 
  deeper 
  focus 
  (fig. 
  1). 
  In 
  a 
  lateral 
  

   view 
  of 
  the 
  mouth 
  capsule 
  the 
  dorsal 
  wall 
  presents 
  a 
  series 
  of 
  narrow 
  

   lacunae 
  (fig. 
  1). 
  In 
  dorsal 
  view 
  these 
  spaces 
  appear 
  as 
  a 
  series 
  

   of 
  circular 
  openings 
  arranged 
  in 
  two 
  rows, 
  one 
  on 
  each 
  side 
  of 
  the 
  

   dorsal 
  gutter. 
  In 
  most 
  specimens 
  only

  four 
  to 
  five

  can 
  be 
  distinguished 
  on 
  each 
  side 
  of 
  the 
  dorsal 
  gutter. 
  The 
  number 
  

   of 
  distinguishable 
  openings 
  on 
  each 
  side 
  of 
  the 
  dorsal 
  gutter 
  was 
  

   found 
  to 
  exceed 
  five 
  in 
  several 
  specimens 
  examined, 
  the 
  maximum 
  

   number 
  of 
  openings 
  that 
  could 
  be 
  seen 
  on 
  each 
  side 
  being 
  nine. 
  

   The 
  two 
  ventral 
  teeth 
  are 
  triangular 
  in 
  shape, 
  the 
  apex 
  of 
  the 
  tri- 
  

   angle 
  being 
  rather 
  sharp. 
  The 
  esophagus 
  is 
  from 
  558 
  to 
  738jj. 
  long 
  

   by 
  144 
  to 
  198^ 
  in 
  maximum 
  width. 
  The 
  nerve 
  ring 
  is 
  located 
  at 
  a 
  

   distance 
  of 
  from 
  400 
  to 
  440[x 
  from 
  the 
  anterior 
  extremity 
  of 
  the 
  body. 
  

   The 
  excretory 
  pore 
  is 
  slightly 
  posterior 
  to 
  the 
  nerve 
  ring 
  and 
  the 
  

   cervical 
  papillae 
  are 
  a 
  little 
  posterior 
  to 
  the 
  excretory 
  pore.
