parallel  to  the  long  axis  of  the  body.  The  second  and  third  segments 
produced  inferiorly  below  the  level  of  the  first  and  of  the  rest,  carinate 
at  the  sides,  but  only  very  obsoletely  carinate  above.  The  fourth  carinate 
above  and  at  the  sides.  The  rest  of  the  somites  with  their  posterior 
half  carinate  from  summit  to  base;  with  five  carinas  on  the  dorsum 
between  the  poriferous  carinas  and  about  twelve,  decreasing  in  size, 
between  the  base  of  the  legs  and  the  poriferous  carina;  the  carinas 
entire,  marked  but  not  divided  by  a  fine  transverse  sulcus  and  not 
extending  posteriorly  beyond  the  margin  of  the  tergite.  The  pore  situated 
on  a  rounded,  smooth  tubercle,  which  is  placed  on  the  anterior  portion 
of  one  of  the  keels;  areas  between  the  keels  not  sculptured.  The 
cylindrical  portion  of  the  somites  very  closely  granular  in  front,  finely 
ridged  behind.  Anal  tergite  not  carinate ,  with  convex  posterior  border  ; 
anal  valves  convex,  with  margins  not  compressed. 
No.  of  somites  about  74. 
Length  up  to  about  42  mm. 
Thic  species  is  rather  larger  than  G.  calva,  from  which  it  may  be 
recognised  by  its  almost  entirely  undivided  crests,  and  by  the  absence 
of  carinas  from  the  dorsum  of  the  second  and  third  tergites.

Java:  Buitenzorg.  One  specimen. 
Resembling  C.  calva  in  size  and  colour,  except  that  the  head  is 
fuscous  above ,  and  the  pale  of  the  lower  surface  not  distinctly  defined. 
The  head  is  closely  hairy  below  ;  on  one  side  the  eyes  consist  of  three 
distinct  ocelli,  on  the  other  side  there  are  two  smaller  ocelli  situated 
behind  the  three.  The  first  tergite  it  distinctly  carinate  laterally;  and 
the  second  and  third  furnished  with  distinct  carinae  above.  The  keels 
are  more  strongly  developed ,  evidently  bifid  and  extend  at  the  hinder 
end  of  the  body  in  the  form  of  teeth  beyond  the  posterior  border  of 
the  tergites.  Moreover  the  pore-bearing  tubercle  is  larger  than  in  calva.
