  Station 
  2228, 
  September 
  11, 
  north 
  lat. 
  37° 
  25',

  long.

   fathoms, 
  brown 
  mud, 
  temperature 
  37°; 
  one 
  young 
  specimen, 
  in 
  bad 
  

   condition 
  (8543). 
  

  

  In 
  this 
  specimen 
  the 
  rostrum 
  is 
  much 
  longer 
  than 
  in 
  the 
  adults 
  origi- 
  

   nally 
  described, 
  being 
  only 
  a 
  little 
  less 
  than 
  half 
  as 
  long 
  as 
  the 
  rest 
  of 
  the 
  

   carapax, 
  and 
  has 
  the 
  terminal 
  fourth 
  of 
  its 
  length 
  slender 
  and 
  unarmed. 
  

   The 
  eyes 
  are 
  proportionally 
  larger 
  than 
  in 
  the 
  adults, 
  as 
  usual 
  in 
  the 
  

   young. 
  In 
  other 
  respects 
  the 
  specimen 
  agrees 
  essentially 
  with 
  the 
  

   adults 
  referred 
  to.

  Notostomus 
  vescus, 
  sp. 
  nov. 
  

  

  This 
  species, 
  although 
  represented 
  only 
  by 
  a 
  single 
  imperfect 
  male 
  

   specimen, 
  is 
  so 
  different 
  from 
  the 
  other 
  species 
  of 
  the 
  genus 
  that 
  I 
  ven- 
  

   ture 
  to 
  describe 
  it. 
  It 
  has 
  no 
  dorsal 
  tooth 
  on 
  the 
  third 
  somite 
  of 
  the 
  

   pleon, 
  the 
  carapax 
  is 
  apparently 
  not 
  at 
  all 
  gibbous, 
  and 
  the 
  dorsum 
  is 
  

   nearly 
  straight. 
  It 
  is 
  probably 
  a 
  very 
  much 
  smaller 
  species 
  than 
  the 
  

   robustus, 
  yibbosus, 
  or 
  elegans, 
  and 
  is 
  perhaps 
  more 
  nearly 
  allied 
  to 
  JV.
