  between 
  it 
  and 
  the 
  still 
  earlier 
  Aphareus 
  inennis 
  of 
  Paulson 
  

   tend 
  to 
  lose 
  tlieir 
  importance. 
  One 
  specimen 
  among 
  Borra- 
  

   daile's 
  material 
  has 
  the 
  rostral 
  crest 
  shaped 
  almost 
  exactly 
  

   as 
  in 
  Paulson^s 
  figure, 
  owing, 
  apparently, 
  to 
  the 
  breaking 
  of 
  

   the 
  anterior 
  tooth 
  ; 
  the 
  greater 
  stoutness 
  of 
  the 
  third 
  cheliped 
  

   as 
  figured 
  by 
  Paulson 
  is 
  not 
  likely 
  to 
  be 
  a 
  valid 
  specific 
  

   character 
  in 
  view 
  of 
  the 
  great 
  difference 
  between 
  the 
  sexes 
  

   ill 
  this 
  respect 
  ; 
  and 
  the 
  number 
  of 
  articulations 
  in 
  the 
  pen- 
  

   idtimate 
  segment 
  of 
  the 
  third 
  maxilliped 
  is 
  sometimes 
  diffi- 
  

   cult 
  to 
  determine 
  unless 
  the 
  limb 
  be 
  removed 
  from 
  the 
  body. 
  

   The 
  decision 
  on 
  this 
  point, 
  however^ 
  may 
  be 
  left 
  to 
  Dr. 
  Balss, 
  

   who, 
  I 
  understand, 
  has 
  under 
  examination 
  specimens 
  be- 
  

   longing 
  to 
  this 
  genus 
  from 
  tlie 
  Red 
  Sea. 
  

  

  There 
  remains 
  for 
  consideration 
  the 
  systematic 
  place 
  to 
  be 
  

   assigned 
  to 
  the 
  genus, 
  and 
  on 
  this 
  point 
  I 
  find 
  myself 
  

   unable 
  to 
  agree 
  with 
  Borradaile's 
  suggestion 
  that 
  its 
  affini- 
  

   ties 
  are 
  with 
  the 
  Sicyoninae. 
  The 
  characters 
  enumerated 
  in 
  

   my 
  former 
  pnper 
  appear 
  to 
  show 
  conclusively 
  that 
  it 
  belongs 
  

   to 
  the 
  Sergcstidse, 
  and 
  in 
  addition 
  it 
  may 
  be 
  pointed 
  out 
  

   that 
  the 
  branched 
  form 
  of 
  the 
  adult 
  male 
  petasma 
  is 
  very 
  

   suggestive 
  of 
  that 
  found 
  in 
  Seryestes

  and 
  

   qiute 
  unlike 
  that 
  of 
  Sicyonia. 
  The 
  modification 
  of 
  the 
  inner 
  

   flagellum 
  of 
  the 
  autennule 
  in 
  the 
  adult 
  male, 
  as 
  described 
  

   above, 
  is 
  prol)ably 
  to 
  be 
  compared 
  with 
  the 
  prehensile 
  

   apparatus 
  of 
  Sergestes, 
  although 
  the 
  flagellam 
  is 
  not 
  bifur- 
  

   cated 
  as 
  in 
  that 
  genus.

  During 
  the 
  last 
  ten 
  years 
  Mr. 
  John 
  Graham 
  has 
  from 
  time 
  

   to 
  time 
  sent 
  several 
  small 
  collections 
  of 
  fishes 
  from 
  Yunnan 
  

   to 
  the 
  British 
  Museum; 
  one 
  just 
  received 
  is 
  likely 
  to 
  be 
  the 
  

   lust, 
  as 
  Mr. 
  Graham 
  is 
  leaving 
  Yunnan 
  ; 
  it 
  includes 
  examples
