  cuts 
  through 
  the 
  lip 
  of 
  the 
  funnel. 
  

  

  Fig. 
  32 
  cuts 
  through 
  the 
  middle 
  of 
  the 
  funnel 
  ; 
  it 
  shows 
  the 
  sperni-duc 
  

   issuing 
  from 
  the 
  extreme 
  ventral 
  margin, 
  and 
  a 
  few 
  spermatozoa, 
  with 
  

   which 
  the 
  segment 
  is 
  filled, 
  are 
  seen 
  entering 
  the 
  mouth 
  of 
  the 
  duct, 
  

   Eig. 
  33 
  cuts 
  across 
  the 
  sperm-duct 
  as 
  it 
  bends 
  backwards 
  behind 
  the 
  

   funnel 
  ; 
  a 
  spermatozoa 
  is 
  seen 
  in 
  the 
  duct 
  as 
  a 
  small 
  dot. 
  (This

   rig. 
  34, 
  which 
  is 
  from 
  a 
  section 
  between 
  those 
  drawn 
  in 
  figs. 
  16 
  and 
  17, 
  

   involves 
  the 
  lip 
  of 
  the 
  funnel 
  and 
  the 
  root 
  of 
  the 
  second 
  testis, 
  below 
  

   which 
  is 
  the 
  sperm-duct. 
  

   EiG. 
  35 
  is 
  an 
  enlarged 
  view 
  of 
  a 
  section 
  near 
  that 
  represented 
  in 
  fig. 
  IS. 
  

   Tlie 
  funnel 
  is 
  no 
  longer 
  present 
  ; 
  the 
  second 
  testis 
  is 
  seen, 
  and 
  the 
  sperm-duct 
  

   is 
  cut 
  through 
  below 
  the 
  testes, 
  and 
  again 
  on 
  the 
  right 
  of 
  the 
  figure. 
  

  

  Fig. 
  36, 
  from 
  a 
  section 
  intervening 
  between 
  those 
  represented 
  in 
  figs. 
  19 
  and 
  

   20, 
  shows 
  the 
  sperm-duct 
  passing 
  upwards 
  behind 
  the 
  septum. 
  The 
  ciliation 
  

   of 
  the 
  duct 
  is 
  shown 
  in 
  this 
  figure. 
  

  

  Pig. 
  37. 
  — 
  A 
  longitudinal 
  section 
  through 
  the 
  second 
  sperm-fuunel 
  and 
  duct 
  

   and 
  the 
  ovary 
  of 
  the 
  immature 
  specimen. 
  (Camera, 
  x 
  700.) 
  

  

  Pigs. 
  38 
  — 
  42 
  represent 
  a 
  series 
  of 
  successive 
  but 
  not 
  consecutive 
  transverse 
  

   sections 
  showing 
  the 
  oviduct. 
  (Camera, 
  x 
  120.) 
  

  

  In 
  fig. 
  38 
  all 
  the 
  organs 
  in 
  the 
  left 
  half 
  of 
  the 
  section 
  are 
  shown 
  ; 
  in 
  the 
  

   remainder 
  only 
  the 
  organ 
  in 
  question. 
  In 
  this 
  section 
  the 
  oviducal 
  

   funnel 
  is 
  cut 
  through 
  at 
  about 
  its 
  widest 
  part, 
  but 
  somewhat 
  obliquely. 
  

   Pig. 
  39 
  (which 
  represents 
  the 
  fourth 
  section 
  after 
  the 
  previous 
  one) 
  cuts 
  

   through 
  the 
  lower 
  part 
  of 
  the 
  funnel, 
  which 
  was 
  torn 
  in 
  the 
  section 
  (cf. 
  

   fig. 
  44). 
  In 
  this 
  figure 
  half 
  of 
  the 
  copulatory 
  gland 
  is 
  seen 
  (cf. 
  fig. 
  30). 
  

   Pig. 
  40 
  (the 
  fourth 
  section 
  beyond 
  the 
  previous 
  one) 
  cuts 
  the 
  oviduct 
  

  

  somewhere 
  about 
  the 
  middle 
  of 
  its 
  course. 
  

   Pig. 
  41 
  represents 
  the 
  eighth 
  section 
  from 
  the 
  last, 
  shows 
  the 
  duct 
  

   entering 
  the 
  body-wall, 
  which 
  is 
  here 
  and 
  in 
  the 
  next 
  few 
  sections 
  

   much 
  thicker 
  than 
  elsewhere. 
  

   Pig. 
  42 
  is 
  the 
  third 
  from 
  the 
  preceding 
  ; 
  the 
  duct 
  is 
  now 
  close 
  to 
  the 
  

   epidermis. 
  In 
  the 
  following 
  section 
  (not 
  figured) 
  the 
  duct 
  opens 
  to 
  the 
  

   exterior 
  below 
  the 
  prominence 
  (p.), 
  due 
  to 
  the 
  greater 
  development 
  of 
  

   the 
  longitudinal 
  muscles 
  of 
  the 
  body-wall. 
  

   Pig. 
  43. 
  — 
  The 
  oviduct 
  (in 
  longitudinal 
  section) 
  of 
  the 
  immature 
  specimen. 
  

   (Camera, 
  X 
  120.) 
  It 
  shows 
  practically 
  its 
  full 
  length, 
  and 
  it 
  will 
  be 
  noticed 
  

   that 
  it 
  reaches 
  back 
  aa 
  far 
  as 
  the 
  chsetal 
  muscles. 
  

  

  Pig. 
  44.--A 
  transverse 
  section 
  of 
  the 
  oviducal 
  funnel 
  (see 
  fig. 
  39), 
  the 
  wall 
  

   of 
  which 
  has 
  been 
  ruptured 
  during 
  manipulation.
