﻿304 
  COLLECTIONS 
  FROM 
  MELANESIA. 
  

  

  of 
  Wales 
  Channel 
  (7-9 
  fms.). 
  The 
  antennae 
  are 
  imperfect. 
  Two 
  

   specimens, 
  of 
  unknown 
  locality, 
  are 
  in 
  the 
  British 
  Museum 
  from 
  the 
  

   collection 
  of 
  H.M.S. 
  ' 
  Herald.' 
  

  

  The 
  mandible, 
  in 
  its 
  broad 
  and 
  strongly 
  dentated 
  apex, 
  closely 
  re- 
  

   sembles 
  that 
  of 
  C. 
  schi'ddtei. 
  

  

  Cirolana 
  latisti/lis, 
  Dana, 
  from 
  the 
  Balabac 
  Straits, 
  is 
  very 
  imper- 
  

   fectly 
  described, 
  but 
  appears 
  to 
  be 
  distinguished 
  from 
  this 
  species 
  by 
  

   the 
  much 
  broader 
  inner 
  ramus 
  of 
  the 
  uropoda. 
  

  

  (i 
  Cirolana 
  lata, 
  HasweU, 
  var. 
  Integra. 
  

  

  Three 
  small 
  specimens 
  from 
  Albany 
  Island, 
  3-4 
  fms., 
  are 
  referred 
  

   with 
  much 
  hesitation 
  to 
  this 
  species. 
  In 
  the 
  broadly 
  ovoid 
  form 
  of 
  

   the 
  body, 
  with 
  its 
  longer 
  first 
  thoracic 
  segment 
  and 
  short 
  post- 
  

   abdomen, 
  they 
  resemble 
  Mr. 
  Haswell's 
  figure 
  and 
  description* 
  ; 
  but 
  

   the 
  terminal 
  postabdominal 
  segment 
  is 
  less 
  acute 
  than 
  in 
  the 
  figure, 
  

   and 
  there 
  is 
  no 
  tooth 
  upon 
  the 
  inner 
  edge 
  of 
  the 
  inner 
  ramus 
  of 
  the 
  

   uropoda. 
  I 
  may 
  add, 
  in 
  reference 
  to 
  some 
  points 
  that 
  are 
  not 
  

   mentioned 
  in 
  Mr. 
  Haswell's 
  description, 
  that 
  the 
  eyes 
  are 
  black 
  and 
  

   subijuadrate, 
  the 
  median 
  rostral 
  point 
  prominent 
  and 
  prolonged 
  

   between 
  the 
  bases 
  of 
  the 
  anteunules 
  to 
  or 
  nearly 
  to 
  the 
  apex 
  of 
  

   the 
  interantennal 
  plate, 
  which 
  is 
  nearly 
  of 
  the 
  same 
  form 
  as 
  in 
  

   C. 
  scJiiodtei, 
  but 
  is 
  without 
  a 
  superficial 
  tooth 
  ; 
  the 
  apex 
  of 
  the 
  

   mandible 
  is 
  broad 
  and 
  dentated 
  as 
  in 
  other 
  species 
  of 
  the 
  genus 
  ; 
  the 
  

   basal 
  joint 
  of 
  the 
  antennules 
  is 
  large 
  and 
  considerably 
  dilated 
  ; 
  the 
  

   fiagellum 
  of 
  the 
  antennae 
  (which 
  is 
  short 
  and 
  scarcely 
  reaches 
  beyond 
  

   the 
  posterior 
  margin 
  of 
  the 
  first 
  body-segment, 
  as 
  in 
  Haswell's 
  figure) 
  

   is 
  13-15-jointed.

  A 
  single 
  female 
  is 
  referred 
  here 
  in 
  Dr. 
  Coppinger's 
  collection 
  from 
  

   Prince 
  of 
  AVales 
  Channel, 
  7-9 
  fms., 
  which 
  has 
  lost 
  the 
  inner 
  ramus 
  

   of 
  both 
  uropoda. 
  

  

  Specimens 
  are 
  in 
  the 
  British-Museum 
  collection 
  from 
  Moreton 
  

   Bay. 
  

  

  If 
  a 
  male 
  and 
  female 
  from 
  Ceylon 
  {E. 
  W. 
  H. 
  Holdsworth) 
  and 
  

   a 
  male 
  from 
  the 
  Gulf 
  of 
  Suez 
  are 
  correctly 
  regarded 
  as 
  identical 
  

   with 
  this 
  species 
  (and 
  they 
  do 
  not 
  seem 
  to 
  differ 
  markedly 
  from 
  the 
  

   Australian 
  examples), 
  this 
  must 
  be 
  a 
  widely 
  distributed 
  Oriental 
  

   form. 
  A 
  large 
  specimen 
  from 
  the 
  West-African 
  coast 
  (without 
  

   special 
  indication 
  of 
  localitj') 
  comes 
  very 
  near 
  to 
  this 
  species, 
  but 
  

   has 
  a 
  more 
  acute 
  and 
  prolonged 
  front 
  and 
  posterior 
  epimera, 
  and 
  

   differs 
  slightly 
  in 
  the 
  proportionate 
  length 
  of 
  the 
  joints 
  of 
  the 
  

   antennae 
  and 
  antennules, 
  and 
  may 
  be 
  distinct. 
  Messrs. 
  Schiodte 
  

   and 
  Meinert's 
  types 
  were 
  from 
  the 
  Philippines 
  and 
  Calcutta. 
  

  

  Mr. 
  Haswell 
  has 
  described 
  a 
  species, 
  Rocinela 
  vigilavs, 
  from 
  

   Holborn 
  Island, 
  near 
  Port 
  Denison
