72.  Cryptodesmus  concolor  sp.  n.  Pl.  XXTI,  fig.  14. 
Java:  Tjibodas.  One  female  specimen. 
Very  closely  allied  to  Cr.  wëberi ,  from  which,  however  it  may 
be  recognised  by  the  following  characters. 
On  the  upper  surface  of  the  somites  the  tubercles  are  larger  and 
more  definitely  arranged  in  rows.  There  are  four  rows  of  them  instead 
of  five.  Along  the  posterior  border  of  the  keels  there  are  only  five, 
instead  of  seven,  lobate  teeth.  The  anterior  angles  of  the  keels  are 
less  widely  rounded. 
Length  11.5;  width  2.7. 
73.  Cryptodesmus  sumatranus  sp.  n.  Pl.  XXII,  fig.  14. 
Sumatra  :  Manindjau. 
Closely  allied  to  Cr.  weberi  and  concolor  ;  but  with  the  keels  depressed 
and  following  the  slope  of  the  dorsal  surface.  Moreover,  the  ornamentation 
of  the  back  is  less  distinctly  tubercular,  and  takes  the  form  of  four 
transverse  series  of  quadrate  areas,  and  the  posterior  borders  of  the 
keels  are  much  less  distinctly  toothed. 
In  the  cT  the  keels  are  slightly  elevated  and  do  not  follow  the 
slope  of  the  back.  Copulatory  feet  as  in  figure. 
Length  up  to  15  mm.;  width  4. 
Sub-Order  IULOIDEA,  Pocock. 
To  this  suborder  are  referred  the  Stemmiulidoe  the  Lysiopetalidce, 
the  lulidce  etc.,  the  latter,  as  has  been  suggested  to  me  by  Messrs.  Cook 
and  Collins,  being  capable  of  much  finer  subdivision  than  has  been 
hitherto  attempted. 
Family  cambalidje. 
Cambala,  Gray. 
For  the  synonymy  and  literature  of  this  genus  reference  may  be 
made  to  my  paper  upon  the  Burmese  Iulidse,  Polyzonidae  and  Chor- 
deumidse  published  in  the  Ann.  Mus.  Genov.  XXXIII,  p.  388,  1893. 
1)  A  now  family  for  Slemmiulus  Gervais,  which  on  a  previous  occasion  I  referred  to 
the  Lysiopetalidœ.  The  genus  differs  from  Lysiopetalum  in  having  the  pleural  sutures  open 
—  a  fact  to  which  Mr.  Cook  first  drew  my  attention  —  the  gnathochilarium  differently 
constructed,  the  pedal  laminai  of  a  very  different  form  etc.  (Soe,  however,  Journ.  Linn. 
Soc.  Zool.  XXIV,  pp.  m  etc.).
