  Note. 
  — 
  Since 
  writing 
  the 
  foregoing 
  description, 
  I 
  have 
  seen, 
  through 
  

   favour 
  of 
  Dr. 
  Haast, 
  the 
  Atlas 
  of 
  the 
  Crustacea 
  described 
  by 
  Dana 
  in 
  the 
  

   Zoology 
  of 
  the 
  U.S. 
  Exploring 
  Expedition. 
  Prom 
  the 
  figures 
  alone 
  (not 
  

   having 
  been 
  able 
  to 
  obtain 
  a 
  description), 
  I 
  think 
  that 
  this 
  species 
  may 
  

   prove 
  to 
  be 
  identical 
  with 
  A. 
  australiensis, 
  Dana.
