  15. 
  Galathea 
  spinosirostris, 
  Dana 
  ? 
  

  

  To 
  this 
  species 
  are 
  rather 
  doubtfully 
  referred 
  female 
  specimens 
  

   collected 
  at 
  Marie-Louise 
  Islaud, 
  17 
  fms. 
  (No. 
  186) 
  ; 
  He 
  des 
  Neufs, 
  

   15 
  fms. 
  (No. 
  187) 
  ; 
  aud 
  Providence 
  Island, 
  19 
  fms. 
  (No. 
  187). 
  

  

  These 
  specimens 
  differ 
  from 
  Stimpson's 
  description 
  of 
  Galathea 
  

   lahidolepta 
  *, 
  based 
  on 
  specimens 
  from, 
  the 
  Cape 
  of 
  Good 
  Hope, 
  and 
  

   from 
  a 
  dried 
  example 
  (probably 
  male) 
  in 
  the 
  Museum 
  collection 
  

   from 
  Simon's 
  Bay 
  (J". 
  MacgiUivray, 
  H.M.S, 
  ' 
  Rattlesnake 
  '), 
  only 
  in 
  

   having 
  the 
  strigge 
  of 
  the 
  carapace 
  (in 
  the 
  adult) 
  very 
  scantily 
  

   pubescent, 
  the 
  lateral 
  margins 
  of 
  the 
  carapace 
  armed 
  with 
  nine 
  

   spinules, 
  and 
  the 
  palms 
  of 
  the 
  chelipedes 
  very 
  slender 
  and 
  scarcely 
  

   scabrous 
  above, 
  but 
  they 
  are 
  spinulose 
  and 
  setose 
  nearly 
  as 
  in 
  

   Stimpson's 
  description. 
  

  

  Dana's 
  G. 
  spinosirostris 
  is 
  but 
  briefly 
  described, 
  and 
  he 
  does 
  not 
  

   state 
  how 
  many 
  spinules 
  there 
  are 
  on 
  the 
  lateral 
  margins 
  of 
  the 
  

   carapace 
  in 
  his 
  types, 
  which 
  were 
  from 
  the 
  Sandwich 
  Islands 
  ; 
  the 
  

   description 
  and 
  figures, 
  however, 
  agree 
  fairly 
  well 
  with 
  our 
  specimens. 
  

   Dr. 
  Richters 
  refers 
  to 
  this 
  species 
  specimens 
  from 
  the 
  Fouquets. 
  

  

  Two 
  small 
  specimens 
  from 
  Darros 
  Island, 
  22 
  fms. 
  (No. 
  233), 
  much 
  

   more 
  nearly 
  resemble 
  G. 
  lahidolepta 
  in 
  the 
  more 
  distinctly 
  strigose 
  

   and 
  pubescent 
  carapace, 
  whose 
  lateral 
  margins 
  are 
  armed 
  with 
  seven 
  

   or 
  eight 
  spinules 
  (including 
  the 
  infra-antennal 
  spine). 
  In 
  one 
  of 
  

   these 
  specimens 
  (a 
  male) 
  the 
  palm 
  of 
  the 
  chelipede 
  is 
  more 
  broadly 
  

   dilated 
  and 
  the 
  fingers 
  relatively 
  shorter 
  than 
  in 
  the 
  speciinen 
  from 
  

   Simon's 
  Bay 
  referred 
  to 
  above. 
  

  

  16. 
  Munida 
  edwardsii. 
  (Plate 
  LI. 
  fig. 
  A.) 
  

  

  The 
  carapace, 
  as 
  usual 
  in 
  the 
  genus, 
  is 
  transversely 
  strigose 
  ; 
  the 
  

   strigse 
  ciliated 
  ; 
  the 
  lateral 
  spines 
  of 
  the 
  rostrum 
  are 
  rather 
  more 
  

   than 
  half 
  as 
  long 
  as 
  the 
  median 
  spine 
  ; 
  outside 
  of 
  the 
  lateral 
  rostral 
  

   spines 
  there 
  is 
  a 
  small 
  supraocular 
  spine. 
  The 
  front 
  of 
  the 
  gastric 
  

   region 
  is 
  armed 
  with 
  a 
  transverse 
  series 
  of 
  about 
  eight 
  spinules 
  ; 
  on 
  

   the 
  sides 
  of 
  the 
  carapace, 
  near 
  to 
  the 
  lateral 
  margins, 
  are 
  two 
  

   spinules, 
  situated 
  one 
  in 
  front 
  of 
  and 
  one 
  behind 
  the 
  cervical 
  suture; 
  

   the 
  antero-lateral 
  angles 
  of 
  the 
  carapace 
  are 
  bispinulose, 
  and 
  posterior 
  

   to 
  these, 
  on 
  the 
  lateral 
  margins, 
  are 
  six 
  spines 
  ; 
  the 
  postabdomen 
  is 
  

   without 
  spinules 
  on 
  the 
  dorsal 
  surface, 
  and 
  the 
  lateral 
  margins 
  of 
  

   the 
  second 
  to 
  sixth 
  segments 
  are 
  rounded. 
  The 
  corneae 
  of 
  the 
  eyes 
  

   are 
  considerably 
  dilated 
  ; 
  the 
  terminal 
  peduncular 
  joints 
  of 
  the 
  

   antennules 
  are 
  armed 
  with 
  four 
  spinules, 
  of 
  which 
  one 
  is 
  very 
  long; 
  

   the 
  peduncular 
  joints 
  of 
  the 
  antenna? 
  (except 
  the 
  last) 
  are 
  each 
  

   armed 
  with 
  a 
  spinule 
  (the 
  flagella, 
  both 
  of 
  antennules 
  and 
  antennse, 
  

   are 
  wanting 
  in 
  the 
  single 
  specimen 
  examined). 
  The 
  chelipedes 
  (in 
  

   the 
  male) 
  are 
  rather 
  robust, 
  the 
  merus 
  enlarging 
  distally 
  and 
  armed 
  

   with 
  superficial 
  and 
  marginal 
  spinules 
  at 
  and 
  toward 
  its 
  distal 
  ex- 
  

   tremity 
  ; 
  carpus 
  spinulose 
  above 
  and 
  on 
  the 
  margins 
  ; 
  hand 
  some-
