  Island, 
  or 
  lie 
  des 
  Roches, 
  13-20 
  fms. 
  (No. 
  183), 
  and 
  a 
  imall 
  male 
  

   from 
  Darros 
  Island, 
  22 
  fms. 
  (No. 
  233). 
  

  

  Dana's 
  types 
  were 
  from 
  tlie 
  Hawaiian 
  Islands 
  ; 
  hence 
  this 
  species, 
  

   which 
  was 
  previously 
  unrepresented 
  in 
  the 
  Museum 
  collection, 
  is 
  

   evidently 
  distributed 
  throughout 
  the 
  Oriental 
  Kcgion. 
  

  

  It 
  appears 
  to 
  be 
  very 
  distinctly 
  characterized 
  by 
  the 
  slender 
  and 
  

   very 
  divaricate 
  rostral 
  horns, 
  and 
  the 
  strong 
  spiues 
  of 
  the 
  ptery- 
  

   gostomian 
  regions 
  and 
  basal 
  antennal 
  joints. 
  In 
  the 
  specimens 
  

   before 
  me, 
  the 
  carapace 
  beneath 
  the 
  pubescence 
  is 
  obviously 
  tuber- 
  

   culated, 
  and 
  it 
  is 
  not 
  so 
  broadly 
  ovate 
  as 
  in 
  Dana's 
  figure 
  ; 
  as 
  in 
  

   that 
  figure, 
  there 
  are 
  small 
  lateral 
  epibranchial 
  and 
  intcstiual 
  

   spines. 
  

  

  There 
  is, 
  I 
  think, 
  no 
  sufficient 
  reason 
  for 
  separating 
  this 
  form, 
  

   even 
  as 
  a 
  subgenus, 
  from 
  Chorilia. 
  

  

  In 
  a 
  female 
  from 
  African 
  or 
  Eagle 
  Islands, 
  10 
  fms. 
  (No. 
  184), 
  the 
  

   carapace 
  is 
  still 
  narrower, 
  less 
  distinctly 
  tuberculated, 
  and 
  has 
  

   scarcely 
  any 
  trace 
  of 
  the 
  epibranchial 
  and 
  no 
  intestinal 
  spine 
  ; 
  the 
  

   spines 
  of 
  the 
  rostrum 
  are 
  longer, 
  exceeding 
  the 
  carapace 
  in 
  length 
  ; 
  

   the 
  spines 
  of 
  the 
  basal 
  antennal 
  joints 
  and 
  pterygostomian 
  regions 
  

   shorter 
  (the 
  latter 
  subequal). 
  This 
  I 
  wiU 
  designate 
  L,-ev^, 
  var. 
  

   tenuirostris.

  A 
  young 
  specimen 
  is 
  in 
  the 
  collection, 
  from 
  Marie-Louise 
  Island, 
  

   17 
  fms. 
  (No. 
  186). 
  

  

  Two 
  specimens 
  of 
  this 
  species 
  are 
  in 
  the 
  British-Museum 
  collection 
  

   without 
  special 
  locality 
  {H.M.S. 
  ' 
  Samarang 
  '). 
  Dr. 
  Hilgeudorf's 
  

   specimen 
  was 
  from 
  Mozambique. 
  

  

  As 
  I 
  have 
  elsewhere 
  noted 
  *, 
  this 
  species 
  is 
  very 
  probably 
  identical 
  

   with 
  the 
  earlier 
  described 
  N.

  stimpsonii. 
  (Plate 
  XLVII. 
  fig. 
  A.) 
  

  

  The 
  carapace 
  is 
  of 
  a 
  rather 
  narrow-pyriform 
  shape 
  ; 
  the 
  spines 
  of 
  

   the 
  rostrum 
  rather 
  short, 
  very 
  slightly 
  divergent, 
  and 
  shaped 
  nearly 
  

   as 
  in 
  Eurynome 
  aspera; 
  there 
  are 
  usually 
  two 
  small 
  spinules 
  on 
  

   the 
  front 
  of 
  the, 
  gastric 
  region, 
  and 
  always 
  a 
  strong 
  spine 
  on 
  each 
  

   branchial 
  region. 
  The 
  surface 
  of 
  the 
  carapace 
  has 
  besides 
  several 
  

   broadly 
  dilated, 
  laminate, 
  fiattened 
  expansions, 
  which, 
  when 
  ex- 
  

   amined 
  with 
  a 
  lens 
  of 
  sufficient 
  power, 
  are 
  seen 
  to 
  be 
  themselves 
  

   granulated 
  :— 
  one 
  (longitudinal) 
  on 
  the 
  gastric, 
  one 
  (posteriorly 
  

   emarginate, 
  and 
  bearing 
  a 
  strong 
  dorsal 
  spine) 
  on 
  the 
  cardiac, 
  one 
  

   (transverse) 
  on 
  the 
  iutestinal, 
  one 
  on 
  the 
  hepatic, 
  and 
  four 
  on 
  the 
  

   branchial 
  region 
  grouped 
  around 
  the 
  branchial 
  spine 
  ; 
  also 
  one 
  on 
  

   the 
  posterior 
  margin 
  of 
  the 
  caiapace 
  ; 
  their 
  form 
  will 
  bo 
  best 
  undei-- 
  

   stood 
  by 
  a 
  reference 
  to 
  the 
  figure. 
  The 
  postocular 
  tooth 
  or 
  lobe 
  is 
  

   prominent 
  and 
  triangulate 
  ; 
  there 
  is 
  a 
  small 
  ridge 
  or 
  prominence 
  on
