  of 
  the 
  digits. 
  The 
  raerns 
  is 
  slightly 
  longer 
  than 
  the 
  carapax, 
  excluding 
  

   the 
  rostrum, 
  and 
  reaches 
  by 
  the 
  tips 
  of 
  the 
  antenna! 
  sqales, 
  often 
  by 
  

   halt 
  its 
  length. 
  The 
  carpus 
  is 
  much 
  longer 
  than 
  the 
  merus, 
  and 
  the 
  

   chela 
  is 
  scarcely 
  more 
  than 
  a 
  tenth 
  as 
  long 
  as 
  the 
  carpus. 
  The 
  third, 
  

   fourth, 
  and 
  fifth 
  peraeopods 
  are 
  approximately 
  equal 
  in 
  length 
  and 
  

   nearly 
  as 
  long 
  as 
  the 
  length 
  from 
  tip 
  of 
  rostrum 
  to 
  tip 
  of 
  telson, 
  or 
  even 
  

   considerably 
  longer 
  ; 
  the 
  ischia 
  and 
  meri 
  are 
  armed 
  nearly 
  as 
  in 
  the 
  

   second 
  pair, 
  and 
  the 
  propodi 
  and 
  dactyli 
  have 
  the 
  same 
  structure 
  and 
  

   nearly 
  the 
  same 
  relative 
  proportions 
  as 
  in 
  TV. 
  ensiferus. 
  

  

  The 
  pleon 
  is, 
  in 
  general, 
  as 
  in 
  N. 
  ensiferus 
  ; 
  the 
  dorsum 
  of 
  the 
  third 
  

   somite, 
  however, 
  is 
  slightly 
  prolonged 
  over 
  the 
  fourth, 
  but 
  not 
  in 
  a 
  

   prominent 
  tooth, 
  and 
  the 
  pleuron 
  of 
  the 
  fifth 
  somite, 
  though 
  slightly 
  

   produced 
  posteriorly, 
  is 
  obtusely 
  angular 
  and 
  not 
  prolonged 
  in 
  an 
  acute 
  

   tooth. 
  

  

  The 
  eggs 
  are 
  apparently 
  very 
  slightly 
  smaller 
  than 
  in 
  N. 
  ensiferus, 
  

   measuring 
  about 
  0.52 
  uuu 
  in 
  shorter 
  and 
  0.75 
  D,m 
  in 
  longer 
  diameter. 
  A 
  

   specimen 
  I01 
  uini 
  in 
  length 
  from 
  station 
  2180, 
  was 
  carrying 
  approxi- 
  

   mately 
  20,000 
  eggs, 
  which 
  were 
  equal 
  to 
  nearly 
  one 
  fourth 
  the 
  bulk 
  of 
  

   the 
  animal, 
  exclusive 
  of 
  the 
  eggs.
