  of 
  median 
  size; 
  upper 
  and 
  lower 
  margins 
  of 
  palm 
  marked 
  off 
  by 
  an 
  

   impressed 
  line; 
  oblique 
  liae 
  of 
  inner 
  surface 
  not 
  very 
  prominent, 
  

   with 
  one 
  row 
  of 
  tubercles; 
  the 
  convexity 
  of 
  the 
  lower 
  margm 
  of 
  the 
  

   propodus 
  is 
  interrupted 
  by 
  a 
  veiy 
  shallow 
  sinus 
  behind 
  the 
  thumb; 
  

   fingers 
  broad 
  and 
  flat, 
  intervening 
  space 
  narrower 
  than 
  either 
  finger; 
  

   a 
  very 
  shallow 
  groove 
  through 
  the 
  middle 
  of 
  each 
  finger 
  and 
  a 
  deep 
  

   groove 
  on 
  the 
  proximal 
  half 
  of 
  the 
  dactylus 
  near 
  the 
  upper 
  edge; 
  

   prehensile 
  edges 
  each 
  with 
  two 
  teeth, 
  one 
  near 
  the 
  tip 
  and 
  one 
  near 
  

   the 
  middle, 
  that 
  on 
  the 
  dactylus 
  proximal 
  to 
  that 
  on 
  the 
  immovable 
  

   finger. 
  

  

  The 
  largest 
  specunen 
  has 
  a 
  proportionately 
  large 
  claw, 
  but 
  with 
  

   a 
  shorter 
  palm, 
  and 
  the 
  movable 
  finger 
  is 
  devoid 
  of 
  a 
  tooth 
  at 
  the 
  

   middle; 
  median 
  groove 
  obsolete; 
  immovable 
  finger 
  broken 
  ofi^ 
  at 
  the 
  

   base. 
  This 
  form 
  apparently 
  corresponds 
  to 
  that 
  which 
  is 
  known 
  

   in 
  various 
  other 
  species 
  of 
  fiddlers 
  where 
  the 
  claw 
  may 
  have 
  a 
  very 
  

   short 
  palm 
  and 
  simpler 
  fingers 
  as 
  compared 
  to 
  the 
  normal 
  form 
  in 
  

   that 
  species. 
  

  

  Ambulatory 
  legs 
  with 
  the 
  merus 
  joints 
  expanded, 
  the 
  upper 
  surface 
  

   with 
  few 
  granules, 
  upper 
  edge 
  distinctly 
  serrated. 
  

  

  This 
  species 
  may 
  be 
  distinguished 
  by 
  its 
  almost 
  transverse 
  anterior 
  

   margin, 
  the 
  very 
  long 
  accessory 
  row 
  of 
  granules 
  above 
  the 
  lower 
  

   margin 
  of 
  the 
  orbit, 
  and 
  by 
  the 
  triangular-oblong 
  frontal 
  furrow.

   21.2 
  mm. 
  

  

  This 
  species 
  is 
  represented 
  only 
  by 
  females. 
  

  

  Carapace 
  one 
  and 
  one-half 
  times 
  as 
  broad 
  as 
  long, 
  very 
  convex 
  or 
  

   almost 
  semicylindrical 
  ; 
  surface 
  coarsely 
  granulate, 
  although 
  the 
  

   granules 
  are 
  scarcely 
  visible 
  to 
  the 
  unaided 
  eye 
  ; 
  the 
  branchio-cardiac 
  

   is 
  the 
  deepest 
  of 
  the 
  dorsal 
  furrows; 
  supraorbital 
  margins 
  nearly 
  

   transverse, 
  very 
  sinuous 
  ; 
  the 
  acutely 
  angled 
  anterior 
  tooth 
  is 
  directed 
  

   obliquely 
  forward; 
  lateral 
  margins 
  granulate 
  and 
  obtusely 
  angled 
  a 
  

   little 
  behind 
  the 
  anterior 
  angle; 
  frontal 
  furrow 
  narrow-oblong, 
  tip 
  

   arcuate; 
  an 
  accessory 
  row 
  of 
  granules 
  above 
  the 
  lower 
  margin 
  of 
  the 
  

   orbit, 
  occupying 
  less 
  than 
  one-third 
  the 
  length 
  of 
  the 
  orbit 
  and 
  com- 
  

   posed 
  of 
  seven 
  or 
  eight 
  granules; 
  the 
  row 
  begins 
  at 
  the 
  outer 
  end 
  

   close 
  to 
  the 
  margin, 
  but 
  inwardly 
  diverges 
  from 
  it, 
  being 
  in 
  front 
  

   view 
  transverse 
  or 
  parallel 
  to 
  the 
  eyestalk 
  when 
  folded 
  in 
  the 
  orbit.
