  sures 
  5 
  lines 
  (10^ 
  millim.) 
  in 
  length, 
  and 
  about 
  8k 
  lines 
  (18 
  millim.) 
  

   in 
  breadth. 
  

  

  In 
  two 
  of 
  these 
  specimens 
  the 
  coloration 
  is 
  reddish 
  brown, 
  with 
  

   the 
  verjf 
  short 
  pubescence 
  of 
  a 
  brownish 
  hue 
  ; 
  the 
  three 
  others 
  (103) 
  

   are 
  much 
  paler, 
  and 
  the 
  pubescence 
  is 
  of 
  a 
  light 
  hue. 
  

  

  These 
  specimens 
  agree 
  with 
  Dana's 
  descriptioa 
  and 
  figures 
  in 
  

   tQost 
  particulars, 
  and 
  especially 
  in 
  the 
  very 
  considerable 
  transverse 
  

   width 
  of 
  the 
  carapace, 
  very 
  concave 
  postero-lateral 
  margins, 
  and 
  

   very 
  short 
  pubescence 
  of 
  the 
  carapace, 
  wherein 
  they 
  differ 
  from 
  

   most 
  other 
  species 
  of 
  Acta;a 
  ; 
  the 
  lobes 
  of 
  the 
  an 
  tero- 
  lateral 
  margins 
  

   of 
  the 
  carapace 
  are, 
  however, 
  very 
  indistinct 
  and 
  are 
  themselves 
  

   interrupted 
  ; 
  and 
  the 
  areolae 
  of 
  the 
  upper 
  surface 
  appear 
  to 
  be 
  much 
  

   more 
  strongly 
  defined 
  and 
  separated 
  by 
  deeper 
  furrows 
  than 
  in 
  

   Dana's 
  figure*. 
  His 
  specimens 
  were 
  from 
  the 
  Sooloo 
  Sea 
  or 
  Balabac 
  

   Straits. 
  

  

  Actcea 
  consohrina 
  of 
  Alphonse 
  Milne-Edwards 
  f 
  is 
  a 
  closely 
  allied 
  

   species 
  from 
  Upolu, 
  which, 
  as 
  far 
  as 
  can 
  be 
  learned 
  from 
  the 
  very 
  

   brief 
  diagnosis, 
  is 
  only 
  distinguished 
  by 
  the 
  lighter 
  coloration 
  and 
  

   4-lobed 
  an 
  tero 
  -lateral 
  margins. 
  It 
  may 
  not 
  be 
  distinct 
  from 
  

   A. 
  areolata, 
  or, 
  if 
  distinct, 
  perhaps 
  our 
  specimens 
  should 
  be 
  re- 
  

   ferred 
  to 
  it. 
  

  

  41. 
  Banareia 
  inconspicua. 
  (Plate 
  XIX. 
  fig. 
  C.) 
  

  

  Carapace 
  transverse, 
  moderately 
  convex, 
  everywhere 
  clothed 
  

   with 
  rather 
  short 
  hairs, 
  beneath 
  which 
  the 
  surface 
  is 
  granulated 
  ; 
  

   similar 
  hairs 
  cover 
  the 
  upper 
  surface 
  of 
  the 
  legs 
  ; 
  the 
  carapace 
  is 
  

   not 
  lobulated, 
  nor 
  ai'e 
  the 
  interregional 
  sutures 
  visible 
  ; 
  the 
  front 
  is 
  

   4-lobed, 
  the 
  lobes 
  small, 
  rounded, 
  and 
  equidistant. 
  The 
  antero- 
  

   lateral 
  margins 
  are 
  longer 
  than 
  the 
  postero-lateral, 
  unevenly 
  gra- 
  

   nulated, 
  with 
  very 
  obscure 
  traces 
  of 
  division 
  into 
  teeth 
  or 
  lobes 
  ; 
  the 
  

   postero-lateral 
  margins 
  are 
  strongly 
  concave. 
  The 
  epistoma 
  is 
  

   almost 
  linear-transverse 
  ; 
  the 
  anterior 
  margin 
  of 
  the 
  buccal 
  cavity 
  

   projects, 
  and 
  is 
  divided 
  by 
  two 
  very 
  distinct 
  fissures. 
  The 
  post- 
  

   abdomen 
  presents 
  nothing 
  remarkable. 
  The 
  antennuies 
  are 
  ob- 
  

   liquely 
  folded 
  ; 
  the 
  antennae 
  have 
  a 
  rather 
  stout 
  basal 
  joint, 
  which 
  

   reaches 
  to 
  the 
  infero-lateral 
  angle 
  of 
  the 
  front, 
  and 
  a 
  rather 
  lono- 
  

   flagellum. 
  The 
  ischium-joint 
  of 
  the 
  outer 
  maxillipedes 
  is 
  but 
  little 
  

   longer 
  than 
  the 
  merus, 
  which 
  is 
  nearly 
  quadrate. 
  The 
  chelipedes 
  

   are 
  nearly 
  smooth 
  and 
  unarmed, 
  without 
  spines 
  or 
  tubercles 
  ; 
  the 
  

   merus 
  or 
  arm 
  is 
  trigonous, 
  its 
  upper 
  and 
  lower 
  margins 
  fringed 
  with 
  

   hairs 
  ; 
  the 
  wrist 
  is 
  clothed 
  with 
  hair 
  on 
  its 
  upper 
  and 
  outer 
  surface, 
  

   the 
  angle 
  on 
  its 
  inner 
  surface 
  prominent, 
  but 
  without 
  a 
  tooth 
  or 
  

   spine 
  ; 
  palm 
  also 
  hairy 
  above 
  and 
  on 
  the 
  upper 
  part 
  of 
  its 
  outer 
  sur- 
  

   face, 
  naked 
  on 
  the 
  lower 
  part, 
  where 
  it 
  is 
  punctulatcd, 
  and 
  granu- 
  

   lated 
  on 
  its 
  lower 
  margin 
  ; 
  fingers 
  nearly 
  as 
  long 
  as 
  the 
  palm, 
  naked 
  

   (except 
  at 
  the 
  base 
  of 
  the 
  upper 
  margin 
  of 
  the 
  mobile 
  finger 
  or
