way  between  the  ventral  and  dorsal  series  of  setae;  at  the  left  side 
a  conical  organ  was  everted  through  the  pore.  No  trace  of  a  clitel- 
lum  could  be  detected. 
The  specimen  being  too  small  for  dissection,  it  was  cut  in  serial  sections 
to  examine  it  more  thoroughly.  The  body-wall  is  very  thin,  so  the  blackish 
contents  of  the  intestinal  canal  are  visible  through  it;  however  this 
is  not  the  case  in  the  anterior  thirteen  segments,  which  present  a 
whitish  colour  and  glandular  appearance.  No  doubt  this  is  due  to  the 
much  greater  thickness  of  the  muscular  layers  of  the  body-wall  in  the 
anterior  segments,  for  there  is  not  much  difference  between  the  epi- 
dermic covering  of  the  anterior  and  posterior  body-region,  as  also  has 
been  pointed  out  by  Beddard  for  M.  barwelli.  The  epidermic  layer  of 
our  specimen  however  almost  entirely  consists  of  large,  oval,  glandular 
cells  (goblet-cells),  while  the  columnar  hypodermic  cells  could  scarcely 
be  observed;  the  epidermis  of  M.  barwelli,  according  to  Mr.  Beddard's 
description  seems  not  to  show  such  a  difference  from  that  of  other  Lum- 
bricidae.  In  the  vicinity  of  the  male  pores  I  found  large  groups  of  pyriform 
cells  (Pl.  Ill,  fig.  21),  extending  internally  within  the  longitudinal  muscular 
layer  and  opening  externally  with  slender  processes  between  the  epi- 
dermic cells;  they  consist  of  a  finely  granular  protoplasm  and  their 
nucleus  is  darkly  stained  by  alum  carmine.  Perhaps  those  glandular 
cells  may  be  considered  as  representing  the  failing  clitellum  ;  however 
they  do  not  seem  to  be  observed  neither  by  Beddard  nor  by  Rosa  2). 
The  septa  in  front  of  the  genital  organs  are  very  thick  and  muscular. 
The  pharynx  is  on  its  dorsal  side  covered  by  a  large  mass  of  glandu- 
lar cells,  extending  posteriorly  along  the  lateral  side  of  the  beginning 
of  the  oesophagus;  the  monilated  gizzard  appears  to  commence  in 
I  however  believe  my  statement  to  be  correct,  though  it  is  very  difficult  to  number 
the  segments  accurately,  as  the  setae  in  the  anterior  body-region  are  not  visible  and 
my  material  is  in  too  poor  a  condition  to  make  sections  of  them.  I  now  am  inclined  to 
to  doubt,  whether  the  large  Sumatra-species  really  does  belong  to  the  genus  Moniligas- 
ter-,  for  it  does  possess  characters,  not  to  be  found  in  the  till  now  described  Monili- 
g  aster-species-,  f.  i.  the  position  of  oviducal  pores  on  segment  XIV  and  the  shape  of 
the  prostata-gland,  which  are  long  and  tubular  like  in  Acanthodrilus.  Moreover  the  male 
pores  in  M.  Eoutenii  are  situated  in  front  of  the  dorsal  setae,  and  not  between  the 
ventral  and  dorsal  setae,  as  observed  in  M.  beddardi  and  in  our  specimen  of  Timor.
