  described 
  as 
  tuberculated 
  ; 
  the 
  seventh 
  joint 
  is 
  very 
  short 
  ; 
  the 
  

   eighth 
  slightly 
  curved 
  and 
  nearly 
  as 
  long 
  as 
  the 
  sixth, 
  the 
  terminal 
  

   claw 
  about 
  half 
  as 
  long 
  as 
  the 
  eighth 
  joint 
  ; 
  the 
  two 
  auxiliary 
  claws 
  

   placed, 
  as 
  usual, 
  above 
  the 
  base 
  of 
  the 
  principal 
  claw. 
  The 
  body 
  

   and 
  limbs 
  are 
  clothed 
  with 
  a 
  very 
  short, 
  close 
  pubescence, 
  and 
  the 
  

   joints 
  of 
  the 
  limbs 
  with 
  scattered 
  longer 
  hairs 
  ; 
  the 
  last 
  three 
  joints 
  

   of 
  the 
  ovigerous 
  legs 
  have 
  some 
  rather 
  stronger 
  simple 
  setae, 
  and 
  

   the 
  eighth 
  joints 
  of 
  the 
  legs 
  have 
  each 
  a 
  series 
  of 
  three 
  or 
  four 
  

   spine-like 
  bristles 
  on 
  the 
  under 
  surface 
  near 
  the 
  base. 
  

  

  The 
  single 
  specimen, 
  which 
  is 
  in 
  very 
  imperfect 
  condition, 
  is 
  

   from 
  Port 
  Jackson. 
  As 
  no 
  traces 
  of 
  the 
  ovary 
  could 
  be 
  seen, 
  I 
  

   think 
  it 
  is 
  a 
  male. 
  

  

  This 
  specimen 
  resembles 
  the 
  British 
  form 
  designated 
  A. 
  hispida 
  

   by 
  Hodge 
  * 
  (which 
  is 
  probably 
  a 
  mere 
  variety 
  of 
  A. 
  I(evis) 
  rather 
  

   than 
  the 
  typical 
  A. 
  lavis, 
  as 
  represented 
  in 
  that 
  author's 
  figures, 
  in 
  

   the 
  form 
  of 
  the 
  rostrum 
  and 
  abdomen, 
  but 
  the 
  leg-bearing 
  pro- 
  

   cesses 
  of 
  the 
  segments 
  of 
  the 
  body 
  are 
  more 
  closely 
  approximated 
  

   and 
  the 
  animal 
  more 
  densely 
  pubescent 
  than 
  in 
  either 
  form. 
  I 
  do 
  

   not 
  observe 
  the 
  "circlet 
  of 
  little 
  spines" 
  at 
  the 
  extremity 
  of 
  the 
  

   first 
  joint 
  of 
  the 
  mandibles 
  mentioned 
  by 
  Hodge 
  in 
  his 
  diagnosis 
  of 
  

   A. 
  hispida. 
  Bohm 
  f 
  refers 
  s])ecimens 
  from 
  Kerguelen 
  Island 
  to 
  

   this 
  species 
  ; 
  but 
  his 
  figure 
  of 
  the 
  palpus 
  differs 
  markedly 
  from 
  the 
  

   same 
  limb 
  as 
  figured 
  by 
  Hodge 
  in 
  A. 
  la 
  vis. 
  

  

  There 
  are 
  in 
  the 
  British-Museum 
  collection 
  two 
  specimens 
  of 
  

   uncertain 
  British 
  locality, 
  probably 
  referable 
  to 
  A. 
  la'vis; 
  but 
  they 
  

   are 
  in 
  a 
  verj- 
  bad 
  state 
  of 
  preservation, 
  being 
  gummed 
  iipon 
  card- 
  

   board, 
  and 
  can 
  scarcely 
  be 
  identified 
  with 
  certainty. 
  

  

  It 
  is 
  to 
  be 
  regretted 
  that 
  during 
  the 
  transference 
  of 
  the 
  specimen 
  

   from 
  spirit 
  to 
  the 
  slide 
  on 
  which 
  it 
  is 
  mounted 
  for 
  the 
  microscope, 
  

   the 
  eiglith 
  joint 
  of 
  the 
  only 
  perfect 
  leg 
  was 
  lost; 
  but 
  the 
  figure, 
  

   which 
  was 
  outlined 
  while 
  the 
  specimen 
  was 
  yet 
  in 
  spirit, 
  represents 
  

   with 
  sufficitnt 
  accuracy 
  the 
  form 
  of 
  this 
  joint. 
  

  

  This 
  species 
  is 
  referable 
  to 
  the 
  genus 
  Achelia 
  as 
  limited 
  by 
  Dr. 
  

   Hoek 
  in 
  his 
  recent 
  Classification 
  of 
  the 
  PycnogonidaJ. 
  

  

  Dr. 
  Anton 
  Dohrn 
  § 
  has 
  united 
  this 
  genus 
  (with 
  several 
  others) 
  

   with 
  AmmotJiea, 
  and 
  the 
  distinctions 
  separating 
  these 
  t^cuera 
  are 
  

   certainly 
  very 
  slight. 
  I 
  think 
  it 
  better, 
  however, 
  having 
  only 
  two 
  

   species 
  under 
  consideration, 
  to 
  refer 
  them 
  to 
  the 
  genera 
  as 
  charac- 
  

   terized 
  by 
  Hoek, 
  his 
  being 
  a 
  complete 
  synopsis 
  of 
  the 
  known 
  

   genera 
  and 
  sj^ecies 
  of 
  the 
  group.
