  along 
  their 
  inner 
  margins, 
  which 
  are 
  strongly 
  dentated. 
  Ambulatory 
  

   legs 
  very 
  hairy 
  and 
  pubescent, 
  with 
  the 
  merus-joiut 
  slightly 
  com- 
  

   pressed, 
  but 
  not 
  dilated 
  ; 
  dactyli 
  unarmed 
  on 
  the 
  inferior

   and 
  terminating 
  in

  small 
  corneous 
  claw. 
  Colour

  white. 
  Length 
  of 
  carapace

  The 
  single 
  female 
  in 
  the 
  collection 
  was 
  obtained 
  at 
  the 
  Seychelles 
  

   (4-12 
  fms.). 
  

  

  The 
  species 
  described 
  by 
  A. 
  M.-Edwards 
  as 
  Carclnoplax 
  setosa, 
  

   from 
  New 
  Caledonia 
  *, 
  resembles 
  this 
  form 
  in 
  many 
  of 
  its 
  characters, 
  

   but 
  has 
  a 
  narrower, 
  more 
  arcuate 
  front, 
  and 
  doutated 
  antero-lateral 
  

   margins. 
  To 
  it 
  I 
  refer 
  a 
  specimen 
  from 
  the 
  Fijis, 
  Totoya 
  {H.M.S. 
  

   '^ 
  HeralcV), 
  and 
  perhaps 
  two 
  from 
  the 
  Philippines, 
  13ohol 
  {Cuming), 
  

   in 
  the 
  British-Museum 
  collection, 
  

  

  Geratoplax 
  arcaata, 
  described 
  in 
  the 
  earlier 
  part 
  of 
  this 
  Report, 
  is 
  

   at 
  once 
  distinguished 
  by 
  the 
  very 
  differently 
  shaped 
  carapace, 
  acute- 
  

   edged 
  eye-peduncles, 
  &c. 
  

  

  61, 
  Grapsus 
  maculatus 
  {Cateshy). 
  

  

  Two 
  adult 
  females 
  of 
  this 
  very 
  common 
  and 
  widely 
  distributed 
  

   species 
  are 
  in 
  the 
  collection 
  from 
  African 
  Island 
  (No. 
  210). 
  To 
  

   the 
  localities 
  mentioned 
  in 
  my 
  lleport 
  in 
  1879 
  on 
  the 
  Transit-of- 
  

   Venus 
  Crustacea 
  (t. 
  c. 
  p. 
  489), 
  the 
  following 
  are 
  to 
  be 
  added 
  : 
  — 
  

   Canaries, 
  Teneriffe 
  {Old 
  Collection); 
  Lanzarote 
  {Rev. 
  li. 
  T. 
  Lowe); 
  

   Madagascar, 
  Tamatave 
  {Rev. 
  Deans 
  Cowan) 
  ; 
  Amboina 
  {coll. 
  Dr. 
  

   BleeJcer) 
  ; 
  and 
  Loyalty 
  Islands, 
  Lifu 
  {Rev. 
  S. 
  J. 
  Whitmee). 
  

  

  This 
  species, 
  as 
  hitherto 
  recorded, 
  ranges 
  throughout 
  the 
  Oriental 
  

   Region 
  southward 
  to 
  the 
  Cape 
  of 
  Good 
  Hope 
  and 
  New 
  Zealand, 
  

   eastward 
  to 
  the 
  coasts 
  of 
  California 
  and 
  Peru, 
  and 
  occurs 
  in 
  the 
  

   Atlantic 
  Region 
  at 
  the 
  Canary 
  and 
  Cape-Vcrd 
  Islands 
  and 
  St. 
  

   Helena, 
  and 
  on 
  the 
  American 
  coasts 
  and 
  islands 
  from 
  Florida 
  to 
  

   Pernambueo 
  {cf. 
  Kingsley,

  Acad. 
  Nat.

  193,

   who 
  has 
  shown 
  that 
  Catesby's 
  designation 
  maculatus 
  must 
  be 
  used 
  

   for 
  this 
  species 
  instead 
  of 
  pictus 
  of 
  Latreille). 
  I 
  have 
  never 
  seen 
  

   the 
  edition 
  of 
  Catesby's 
  work 
  published 
  in 
  1771. 
  In 
  the 
  original 
  

   and 
  pre-Linnean 
  edition 
  (1743) 
  the 
  figure 
  and 
  description 
  are 
  so 
  

   bad 
  as 
  to 
  be 
  scarcely 
  recognizable.

  this 
  common 
  species,

  is
