  of 
  the 
  subsegment; 
  the 
  sulcus 
  begins 
  on 
  the 
  fifth 
  segment 
  and 
  is 
  obso- 
  

   lete 
  on 
  the 
  seventeenth; 
  it 
  is 
  much 
  shorter 
  and 
  less 
  distinct 
  than 
  in 
  

   M. 
  hartmannu 
  where 
  it 
  reaches 
  nearly 
  to 
  the 
  cariuae, 
  in 
  H. 
  massal 
  only 
  

   about 
  halfway; 
  posterior 
  margin 
  on 
  each 
  side 
  snbdentate 
  with 
  two 
  or 
  

   three 
  broad, 
  sliglitly 
  projecting 
  teeth; 
  the 
  middle 
  of 
  the 
  margin 
  is 
  

   smooth, 
  and 
  there 
  is 
  a 
  smooth 
  space 
  next 
  the 
  carina. 
  

  

  Lateral 
  carinae 
  distinctly 
  more 
  developed 
  than 
  in

   poriferous 
  carinae 
  thickened 
  caudad, 
  slightly 
  more 
  proiuiiieiit 
  laterad 
  

   below 
  the 
  pore 
  than 
  above 
  ; 
  pores 
  facing 
  nearly 
  directly 
  laterad, 
  located 
  

   somewhat 
  in 
  front 
  of 
  the 
  posterior

  of 
  the

  Sterna 
  rather 
  sparsely

  with 
  a 
  distinct,

  not

  sulcus; 
  conic 
  processes 
  very 
  small, 
  obsolete

  males 
  with 
  a 
  short, 
  broad 
  process 
  between 
  the 
  bases 
  of 
  

   the 
  fourth 
  pair 
  of 
  legs; 
  this 
  process 
  ends 
  in 
  two 
  rounded-couic, 
  strongly 
  

   chitinized 
  knobs. 
  

  

  Legs 
  moderately 
  hirsute 
  with 
  rather 
  short 
  hairs

   scarcely 
  crassate, 
  the 
  pads

  curved 
  

   near 
  its 
  base 
  so 
  that 
  the 
  apex 
  lies 
  almost 
  in

  with 
  a 
  broad 
  

   expansion 
  from 
  the 
  anterior

  of 
  the

  near 
  the 
  base 
  of 
  the 
  

   apical 
  process;

  distinct 
  only 
  from 
  near 
  the 
  end 
  of 
  the 
  termi- 
  

   nal

  which 
  bears 
  distally 
  several

  This 
  species 
  was 
  described 
  from 
  a 
  single 
  female 
  specimen, 
  from 
  

   which 
  little 
  can 
  be 
  added 
  to 
  the 
  brief 
  descriptions 
  cited 
  above. 
  An 
  

   identification 
  ought 
  scarcely 
  to 
  be 
  attempted 
  until 
  material 
  can 
  be 
  had 
  

   from 
  the 
  type 
  locality. 
  This 
  is 
  far 
  distant 
  from 
  any 
  of 
  the 
  places 
  in 
  

   which 
  Rabrodesmus 
  has 
  been 
  collected, 
  and 
  aculeatus 
  may 
  easily 
  prove 
  

   to 
  be 
  generically 
  distinct. 
  The 
  habit 
  is 
  somewhat 
  different 
  from 
  that 
  

   of 
  the 
  species 
  of 
  Habrodesmus, 
  more 
  notably 
  in 
  that 
  the 
  carinae 
  are
