  type 
  of 
  their 
  description 
  is 
  in 
  the 
  collection 
  of 
  the 
  British 
  Museum, 
  

   and 
  is 
  of 
  very 
  small 
  size 
  (length 
  G 
  lines, 
  12| 
  millim.) 
  ; 
  surface 
  of 
  the 
  

   carapace 
  nearly 
  smooth, 
  with 
  the 
  regions 
  little 
  prominent 
  and 
  but 
  

   slightly 
  granulated 
  ; 
  a 
  spine 
  on 
  the 
  gastric 
  and 
  cardiac 
  regions 
  and 
  

   a 
  somewhat 
  obscure 
  ridge 
  on 
  the 
  branchial 
  regions 
  ; 
  teeth 
  of 
  the 
  

   antei'o-lateral 
  margins 
  nearly 
  confluent, 
  postero-lateral 
  spines 
  with 
  

   scarcely 
  any 
  traces 
  of 
  lateral 
  teeth 
  &c. 
  Very 
  similar 
  characters 
  are 
  

   exhibited 
  by 
  the 
  small 
  specimen 
  from 
  Port 
  Molle 
  (No. 
  03). 
  In 
  the 
  

   smaller 
  male 
  from 
  Thursday 
  Island 
  (No. 
  177) 
  and 
  in 
  two 
  specimens 
  

   from 
  the 
  Australian 
  seas, 
  the 
  largest 
  of 
  which 
  measures 
  about 
  

   10 
  lines 
  (21 
  millim.), 
  and 
  which 
  were 
  dredged 
  by 
  Mr. 
  Macgillivray 
  

   di;ring 
  the 
  voyage 
  of 
  H.M.S. 
  ' 
  Eattlesnake,' 
  in 
  7 
  fms. 
  between 
  Percy 
  

   Island 
  and 
  the 
  mainland, 
  in 
  lat. 
  21° 
  50' 
  S., 
  long. 
  150° 
  20' 
  E., 
  there 
  

   is 
  a 
  considerable 
  approach 
  to 
  the 
  larger 
  specimens 
  from 
  Thursday 
  

   Island 
  : 
  in 
  all 
  the 
  spines 
  of 
  the 
  gastric 
  and 
  branchial 
  regions 
  are 
  

   nearly 
  obsolete 
  ; 
  but 
  in 
  two 
  specimens 
  the 
  carapace 
  is 
  nearly 
  smooth, 
  

   in 
  the 
  others 
  it 
  is 
  granulated 
  nearly 
  as 
  in 
  the 
  large 
  specimen 
  from 
  

   Dr. 
  Coppinger's 
  collection, 
  the 
  spines 
  of 
  the 
  postero-lateral 
  angles 
  

   are 
  less 
  prominent 
  and 
  less 
  distinctly 
  laciniated 
  than 
  in 
  that 
  example, 
  

   though 
  bearing 
  distinct 
  traces 
  of 
  lateral 
  teeth. 
  

  

  I 
  have 
  entered 
  thus 
  fully 
  into 
  the 
  distinctions 
  observable 
  between 
  

   these 
  specimens, 
  because 
  of 
  the 
  great 
  degree 
  of 
  variability 
  that 
  exists 
  

   in 
  many 
  species 
  of 
  Parthenopidae 
  ; 
  no 
  one, 
  I 
  think, 
  comparing 
  two 
  

   specimens 
  at 
  opposite 
  ends 
  of 
  the 
  series 
  would 
  regard 
  them 
  as 
  be- 
  

   longing 
  to 
  one 
  and 
  the 
  same 
  species.

  A 
  very 
  small 
  male 
  from 
  Thursday 
  Island 
  (No. 
  165) 
  has 
  the 
  cara- 
  

   pace 
  and 
  under 
  surface 
  of 
  the 
  chelipedes 
  smooth, 
  the 
  gastric 
  de- 
  

   pression 
  shallow, 
  and 
  scarcely 
  any 
  trace 
  of 
  the 
  oblique 
  ridges 
  on 
  

   the 
  branchial 
  regions 
  usually 
  characteristic 
  of 
  C 
  fornicata.

  An 
  adult 
  male 
  was 
  received 
  with 
  Dr. 
  Coppinger's 
  second 
  collec- 
  

   tion 
  from 
  Thursday 
  Island, 
  3-4 
  fms.

  7 
  fms. 
  (No.

  The 
  larger 
  examj^le 
  has 
  the 
  carapace 
  more 
  distinctly 
  and 
  coarsely 
  

   pitted 
  than
