  Although 
  there 
  has 
  been 
  no 
  opportunity 
  of 
  directly 
  comparing 
  this 
  

   specimen 
  with 
  the 
  young 
  male 
  originally 
  described 
  from 
  the 
  Blake 
  col- 
  

   lection 
  of 
  1880, 
  I 
  have 
  very 
  little 
  doubt 
  that 
  the 
  two 
  specimens 
  are 
  spe- 
  

   cifically 
  identical. 
  In 
  the 
  present 
  specimen 
  the 
  middle 
  dorsal 
  teeth 
  of 
  

   the 
  fourth 
  and 
  fifth 
  somites 
  of 
  the 
  pleon 
  are 
  a 
  little 
  smaller 
  than 
  in 
  the 
  

   young 
  male, 
  and 
  the 
  dorsal 
  part 
  of 
  the 
  margin 
  either 
  side 
  is 
  dentate, 
  as 
  

   shown 
  in 
  Milne-Ed 
  wards's 
  figure 
  above 
  referred 
  to, 
  while 
  in 
  the 
  young 
  

   male 
  this 
  dentation 
  was 
  either 
  absent 
  or 
  overlooked, 
  as 
  might 
  readily 
  

   have 
  happened 
  in 
  the 
  case 
  of 
  so 
  small 
  an 
  individual. 
  In 
  all 
  other 
  re- 
  

   spects 
  this 
  specimen 
  agrees 
  perfectly 
  with 
  my 
  figures 
  and 
  description 
  

   of 
  the 
  original 
  specimen.
