As  to  the  internal  anatomy  it  could  be  recognized ,  that  the  6th., 
7th.,  8th  and  9th  septum  are  very  thick  and  muscular,  fitting  like 
funnels  one  into  another,  and  totally  inclosing  the  oesophagus.  The 
10th.  septum  is  absent,  or  is  displaced  to  the  limit  between  segment 
XI  and  XII. 
The  gizzard  commences  in  segment  XVII  and  consists  of  eight 
divisions;  in  Desmogaster  doriae  there  are  ten  gizzards;  the  first  of 
them  lying  in  segment  XX.  The  prostate-glands  represent  long , 
tubular  organs,  tapering  towards  their  external  extremity;  their  distal 
portion  however  is  again  broader  and  has  a  somewhat  triangular  shape. 
It  seems  to  me,  that  the  prostate-glands  of  our  specimen  differ  in 
shape  from  those  of  D.  doriae  and  I  also  believe  to  have  observed ,  that 
the  vasa  deferentia  do  not  open  at  the  top  of  those  glands,  as  des- 
cribed by  Rosa. 
Though  only  a  single  specimen  was  collected,  it  furnishes  a  new 
point  of  agreement  between  the  earthworm-fauna  of  the  Indian  con- 
tinent and  the  Malay  Archipelago. 
Ürochaetidae. 
Pontoscolex  Schmarda. 
(Urochaeta  Perrier). 
By  his  recent  examination  of  the  type-specimens  of  Lumbricina,  collec- 
ted and  described  by  Schmarda,  Beddard1)  has  clearly  shown ,  that  the 
genus  Pontoscolex  2)  is  identical  with  Perrier's  genus  Urochaeta.  Now 
Perrier  himself  in  his  first  communication  on  Urochaeta  3)  has  already 
pointed  out  the  close  resemblance  of  the  two  genera;  as  however  Schmarda 
stated,  that  Pontoscolex  possesses  fourteen  series  of  setae,  alternating  in 
the  successive  segments,  instead  of  sixteen,  Perrier  was  quite  right 
in  believing  the  two  genera  to  be  different.  However  according  to 
Beddard's  investigation  of  Pontoscolex,  Schmarda's  enumeration  was 
inaccurate,  there  being  eight  setae  in  each  segment;  the  name  Uro- 
chaeta therefore  ought  to  be  cancelled. 
Pontoscolex  appears  to  have  a  very  wide  geographical  distribution,
