﻿CRUSTACEA,

  In 
  these 
  specimens 
  the 
  catapace 
  is 
  very 
  distinctly 
  granulated 
  over 
  

   its 
  upper 
  surface 
  ; 
  the 
  chclipcdes 
  are 
  hairy 
  on 
  their 
  inner 
  surface, 
  

   but 
  are 
  not 
  ciliated 
  on 
  their 
  margins 
  ; 
  the 
  palm 
  is 
  not 
  carinated 
  ; 
  

   the 
  upper 
  (mobile) 
  finger 
  has 
  the 
  blunt 
  or 
  quadrate 
  tooth 
  on 
  its 
  

   inner 
  margin 
  mentioned 
  by 
  lliippell 
  as 
  characteristic 
  of 
  the 
  male 
  of 
  

   Macrojphthalmus 
  depressus 
  ; 
  the 
  lower 
  finger 
  is 
  slightly 
  deflexed, 
  

   so 
  as 
  to 
  form 
  an 
  angle 
  with 
  the 
  lower 
  margin 
  of 
  the 
  palm, 
  I 
  have 
  

   already 
  referred 
  to 
  Euplax 
  hoscii 
  in 
  the 
  earlier 
  part 
  of 
  this 
  Eeport. 
  

   The 
  carapace 
  is 
  not 
  quite 
  so 
  broad 
  as 
  in 
  Riippell's 
  figure 
  of 
  31. 
  depres- 
  

   sus, 
  based 
  on 
  a 
  female 
  specimen, 
  and 
  the 
  upper 
  orbital 
  margin 
  is 
  

   sinuated, 
  not 
  straight 
  as 
  in 
  that 
  figure 
  ; 
  so 
  that 
  I 
  must 
  regard 
  M. 
  

   de2»\'ssus 
  as 
  a 
  distinct 
  species.

  fenestrata,

  Mozambique, 
  between 
  tide-marks 
  {^o. 
  227), 
  eleven 
  specimens, 
  all 
  

   of 
  them 
  males. 
  

  

  There 
  is 
  in 
  the 
  British-Museum 
  collection 
  a 
  series 
  of 
  specimens 
  of 
  

   both 
  sexes 
  of 
  the 
  allied 
  D. 
  sulcata 
  (Porskal), 
  from 
  the 
  lied 
  Sea. 
  

   The 
  distinctive 
  characters 
  pointed 
  out 
  by 
  Hilgendorf 
  are 
  constant 
  in 
  

   the 
  two 
  series. 
  

  

  D. 
  fenestrata 
  has 
  been 
  hitherto 
  a 
  desideratum 
  to 
  the 
  collection 
  of 
  

   the 
  Museum. 
  Hitherto 
  it 
  has 
  apparently 
  been 
  recorded 
  oidy 
  from 
  

   the 
  east 
  coast 
  of 
  Africa, 
  where 
  it 
  ranges 
  from 
  Ibo 
  to 
  Natal, 
  if 
  (as 
  

   Hilgendorf 
  notes, 
  and 
  as 
  is 
  doubtless 
  correct) 
  the 
  specimens 
  referred 
  

   by 
  Krauss 
  to 
  D. 
  sulcata 
  belong 
  to 
  D. 
  fenestrata.

  (Plate 
  XLVIII. 
  fig, 
  C) 
  

  

  The 
  body 
  and 
  limbs 
  are 
  everywhere 
  clothed 
  with 
  a 
  short 
  close 
  

   pubescence 
  ; 
  the 
  autero-lateral 
  margins 
  of 
  the 
  carapace, 
  the 
  frontal 
  

   region 
  above 
  the 
  anterior 
  margin, 
  and 
  the 
  chelipedes 
  and 
  limbs 
  are 
  

   fringed 
  with 
  longer 
  hairs. 
  Carapace 
  transverse, 
  with 
  the 
  antero- 
  

   lateral 
  margins 
  entire 
  and 
  much 
  shorter 
  than 
  the 
  postero-lateral 
  ; 
  

   the 
  front 
  is 
  about 
  one 
  third 
  the 
  greatest 
  width 
  of 
  the 
  body, 
  some- 
  

   what 
  detlcxed; 
  its 
  anterior 
  margin 
  nearly 
  straight, 
  with 
  a 
  very 
  

   small 
  median 
  notch 
  ; 
  the 
  endostome 
  without 
  longitudinal 
  ridges 
  ; 
  

   the 
  orbital 
  margins 
  entire, 
  without 
  teeth 
  or 
  fissures. 
  The 
  post- 
  

   abdomen 
  (in 
  the 
  young 
  female) 
  has 
  none 
  of 
  the 
  segments 
  coalescent, 
  

   at 
  base 
  it 
  covers 
  the 
  whole 
  width 
  of 
  the 
  sternum. 
  The 
  eye- 
  

   peduncles 
  are 
  pubescent, 
  lie 
  closely 
  within 
  the 
  transverse 
  orbits, 
  and 
  

   have 
  a 
  distinct 
  black 
  cornea 
  ; 
  the 
  basal 
  (or 
  actual 
  second) 
  joint 
  is 
  

   narrow 
  and 
  slender, 
  and 
  does 
  not 
  quite 
  attain 
  the 
  front. 
  The 
  outer 
  

   maxillipedes 
  have 
  a 
  nearly 
  quadrate 
  merus-Joint, 
  with 
  straight 
  

   anterior 
  margin 
  and 
  rounded, 
  not 
  excavated, 
  antero-internal 
  angle. 
  

   The 
  chelipedes 
  are 
  subequal 
  and 
  densely 
  pubescent 
  and 
  hairy 
  ; 
  merus 
  

   short 
  and 
  trigonous, 
  with 
  a 
  small 
  blunt 
  tooth 
  or 
  lobe 
  near 
  the 
  distal 
  

   end 
  of 
  the 
  upper 
  margin 
  ; 
  wrist 
  somewhat 
  angulatod, 
  but 
  not 
  

   toothed 
  on 
  its 
  inner 
  margin 
  ; 
  ]jalm 
  about 
  as 
  long 
  as 
  the 
  wrist, 
  

   rounded 
  above 
  and 
  below 
  ; 
  fingers 
  naked 
  at 
  the 
  tips 
  and 
  meeting
