  This 
  example 
  is 
  a 
  male 
  of 
  moderate 
  size, 
  and 
  resembles 
  the 
  figure 
  

   of 
  Milne-Edwards 
  *, 
  but 
  differs 
  from 
  those 
  of 
  Hilgendorf 
  t 
  and 
  Hoff- 
  

   mann 
  +, 
  who 
  record 
  this 
  species 
  from 
  Zanzibar 
  and 
  Kossi-Be, 
  in 
  

   having 
  the 
  fingers 
  of 
  the 
  larger 
  chelipede 
  destitute 
  of 
  prominent 
  

   teeth 
  or 
  denticles 
  ; 
  the 
  fingers 
  are, 
  however, 
  less 
  elongated 
  than 
  in 
  M.- 
  

   Edwards's 
  figure, 
  based 
  on 
  specimens 
  from 
  Malabar 
  and 
  Samarang 
  ; 
  

   the 
  arm 
  has 
  but 
  a 
  single 
  denticle 
  near 
  the 
  distal 
  end 
  of 
  its 
  anterior 
  

   margin. 
  Its 
  recorded 
  range 
  extends 
  eastward 
  to 
  New 
  Caledonia.

  des 
  Roches, 
  beach 
  (No. 
  210), 
  an 
  adult 
  male. 
  

   This 
  species 
  has 
  been 
  already 
  referred 
  to 
  in 
  the 
  earlier 
  part 
  of 
  

   this 
  lieport 
  (p.

  Three 
  adult 
  males 
  are 
  in 
  the 
  collection, 
  obtained 
  respectively 
  at 
  

   Bird 
  Island, 
  Seychelles, 
  African 
  Island, 
  on 
  the 
  beach, 
  and 
  Providence 
  

   Island 
  ; 
  also 
  an 
  adult 
  female 
  from 
  the 
  lie 
  des 
  Roches 
  (No. 
  210). 
  

   The 
  specimen 
  from 
  Bird 
  Island 
  was 
  found 
  in 
  the 
  interior 
  of 
  the 
  

   island.

  Mahe 
  Island, 
  beach 
  (No. 
  196) 
  ; 
  an 
  adult 
  male. 
  

  

  This 
  species, 
  hitherto 
  a 
  desideratum 
  in 
  the 
  Museum 
  collection, 
  

   is 
  remarkable 
  on 
  account 
  of 
  the 
  extreme 
  smallness 
  and 
  slenderness 
  of 
  

   the 
  chelipcdes 
  in 
  the 
  male, 
  which 
  resemble 
  those 
  of 
  the 
  females 
  in 
  

   many 
  other 
  species. 
  In 
  the 
  specimen 
  before 
  me 
  the 
  fingers 
  are 
  

   slightly 
  infiexed 
  and 
  concave 
  on 
  their 
  inner 
  surfaces, 
  but 
  scarcely 
  

   excavated 
  ; 
  the 
  palms 
  have 
  a 
  patch 
  of 
  hair 
  on 
  their 
  inner 
  surface, 
  

   but 
  apparently 
  no 
  spine. 
  

  

  Dr. 
  Richters 
  records 
  this 
  speciev=i 
  (which 
  was 
  originally 
  described 
  

   from 
  supposed 
  Mauritius 
  examples) 
  from 
  the 
  Eonquets, 
  and 
  M. 
  A, 
  

   Milne-Edwards 
  from 
  Reunion.

  Five 
  males 
  and 
  a 
  female 
  lacking 
  the 
  chelipcdes, 
  obtained 
  on 
  the 
  

   beach 
  at 
  Mozambique 
  (Nos. 
  225, 
  227), 
  are 
  referred 
  to 
  this 
  species, 
  

   to 
  which 
  also 
  belongs, 
  as 
  I 
  think, 
  a 
  very 
  small 
  male 
  from 
  the 
  Red 
  

   Sea, 
  received 
  from 
  the 
  Godcftroy 
  Museum 
  as 
  Macroplitlialmus 
  de- 
  

   jjressus,
