of  them.  As  to  the  structure  of  these  bodies  I  can  entirely  confirm 
Beddard's  observation,  that  they  are  of  quite  a  different  structure 
as  the  diverticula  ;  they  are  solid  and  consist  of  a  number  of  large 
cells ,  which  contain  a  finely  granular  mass  and  a  small  nucleus.  Wether 
however  they  have  the  function  of  capsulogenous  glands,  preparing 
the  albuminous  fluid  of  the  cocoon,  as  suggested  by  this  author,  I 
dare  not  decide;  for  even  with  regard  to  our  common  earthworms, 
we  as  yet  cannot  state  with  certainty  the  function  of  the  different  ge- 
nerative organs  in  the  process  op  copulation.  Moreover  the  fact,  that 
such  forms,  as  Criodrilus,  which  have  large  cocoons,  appear  to  possess 
neither  capsulogenous  glands  nor  even  spermathecae ,  is  not  in  favour 
of  Beddard's  views. 
Small  seminal  vesicles  are  present  in  segment  XI  and  XII.  A  pair 
of  large  lobated  prostate-glands  occupy  segments  XVI— XXII. 
According  to  Rosa's  description,  his  P.  campanulata1)  should  be 
specially  distinguished  from  P.  houlleti  (1)  by  the  shape  of  the  gizzard, 
which  should  not  be  bulb-shaped  as  in  the  last-named  species,  ac- 
cording to  Perrier's  figure,  but  rather  bell-shaped  (forma  campanu- 
lata) ,  and  (2)  by  having  the  oesophagus  dilated  in  front  of  the  giz- 
zard. INow  I  find,  that  in  our  examples  the  oesophagus  really  is  some- 
what widened  out,  before  passing  in  the  gizzard  and  that  the  gizzard 
more  resembles  the  figure ,  published  by  Rosa  ,  than  that  of  Perrier  ; 
I  believe  however  the  latter  one  not  to  be  very  correct,  for  in  his 
description  he  says,  that  the  gizzard  does  not  present  any  particu- 
larity. As  to  the  number  of  the  globular  bodies  of  the  spermathecae, 
of  which  P.  campanulata  should  possess  three,  instead  of  a  single  one, 
as  figured  by  Perrier  in  P.  houlleti,  this  cannot  be  a  character  of 
much  value,  because,  as  I  stated  before,  this  number  is  not  even 
constant  for  all  spermathecae  in  the  same  individual. 
Therefore  I  presume,  that  P.  campanulata  from  Burmah  is  identical 
with  P.  houlleti.  This  species  is  already  known  from  Calcutta,  Dehra 
Dun,  Cochinchina,  Philippines  and  Bahama's.

Java:  Tjibodas,  four  specimens. 
The  length  of  the  largest  example  is  only  25  m.m.  ;  the  number  of 
its  segments  amounts  to  about  80.
