  Transit-of-Yenxis 
  Expedition 
  at 
  Eodriguez, 
  I 
  have 
  already 
  alluded 
  to 
  

   the 
  geographical 
  distribution 
  of 
  this 
  verj' 
  variable 
  species 
  *. 
  

  

  The 
  specimens 
  in 
  the 
  Museum 
  collection 
  are 
  from 
  Eodriguez 
  

   {H. 
  H. 
  Slater) 
  ; 
  Eed 
  Sea, 
  El 
  Tor 
  (Major 
  MacDonald), 
  and 
  Gulf 
  of 
  

   Suez 
  (R. 
  J\Ic 
  Andrew 
  and 
  J. 
  K. 
  Lord) 
  ; 
  Eiji 
  Islands 
  {E.M.S.'Herald'); 
  

   Samoa 
  Islands 
  (Rev. 
  S. 
  J. 
  Whitmee). 
  

  

  The 
  variety 
  meJanodactylus 
  is 
  usually 
  less 
  pubescent 
  than 
  the 
  

   typical 
  C. 
  andreossii, 
  and 
  the 
  lower 
  part 
  of 
  the 
  outer 
  surface 
  of 
  

   the 
  larger 
  chelipede 
  is 
  usually, 
  but 
  not 
  invariably, 
  destitute 
  of 
  

   granules 
  or 
  tubercles. 
  

  

  A 
  male 
  and 
  female, 
  from 
  the 
  Dcedalus 
  Shoal, 
  Red 
  Sea 
  (Lt.-Col. 
  

   Pkujfair), 
  which 
  may 
  be 
  designated 
  C. 
  andreossii, 
  var. 
  quadri- 
  

   lohalHs, 
  are 
  distinguished 
  from 
  all 
  other 
  specimens 
  of 
  the 
  genus 
  I 
  

   have 
  seen 
  by 
  having 
  the 
  front 
  armed 
  with 
  four 
  very 
  distinct 
  equal 
  

   and 
  equidistant 
  rounded 
  lobes 
  or 
  teeth. 
  In 
  this 
  variety 
  the 
  carapace 
  

   is 
  very 
  distinctly 
  granulated 
  on 
  the 
  protogastric 
  and 
  hepatic 
  regions, 
  

   and 
  the 
  chelae 
  tuberculated 
  on 
  the 
  whole 
  of 
  their 
  outer 
  surface, 
  the 
  

   tubercles 
  being 
  very 
  hii'ge, 
  rounded, 
  and 
  granulated 
  on 
  and 
  near 
  the 
  

   upper 
  margin 
  ; 
  the 
  fingers 
  were 
  dark- 
  coloured. 
  

  

  In 
  both 
  specimens 
  there 
  is 
  a 
  red 
  spot 
  on 
  the 
  gastric, 
  cardiac, 
  and 
  

   branchial 
  regions 
  of 
  the 
  carapace. 
  It 
  may 
  perhaps 
  prove 
  to 
  be 
  

   specifically 
  distinct.

  Actumnus 
  setifer 
  (De 
  Haan). 
  

  

  Of 
  this 
  species, 
  upon 
  whose 
  synonymy 
  and 
  distribution 
  I 
  have 
  

   remarked 
  on 
  p. 
  225, 
  a 
  male 
  and 
  three 
  females 
  were 
  collected 
  at 
  the 
  

   Seychelles, 
  4-12 
  fms. 
  (No. 
  194), 
  a 
  small 
  female 
  at 
  He 
  des 
  Neufs, 
  

   15 
  fms. 
  (No. 
  187), 
  and 
  two 
  males 
  and 
  a 
  female 
  at 
  Providence 
  Island, 
  

   17 
  fms. 
  (No. 
  217). 
  

  

  The 
  length 
  of 
  the 
  carapace 
  of 
  the 
  smallest 
  ova-bearing 
  female 
  is 
  

   less 
  than 
  3 
  lines 
  (6 
  millim.). 
  

  

  Actunmus 
  miliaris, 
  A. 
  Milne-Edwards 
  f, 
  an 
  allied 
  species, 
  also 
  from 
  

   the 
  Sevchelles, 
  seems 
  to 
  be 
  well 
  distiuguislied 
  by 
  the 
  much 
  less 
  pro- 
  

   minent 
  and 
  acute 
  lobes 
  of 
  the 
  antero-lateral 
  margins, 
  and 
  by 
  the 
  

   deflexed 
  index 
  or 
  immobile 
  finger 
  of 
  the 
  larger 
  chelipede.

  A

  Specimens 
  from

   Islands 
  (Lt.-Col. 
  Burnahy) 
  possibly 
  belong 
  to 
  a 
  different 
  species, 
  as 
  

   they 
  have 
  the 
  antero-lateral 
  margins 
  of 
  ihe 
  carapace 
  less 
  distinctly
