  As 
  author 
  of 
  one 
  of 
  the 
  pertinent 
  papers 
  mentioned 
  above, 
  I 
  was 
  

   asked 
  by 
  Dr. 
  Fenner 
  A. 
  Chace, 
  Jr., 
  of 
  the 
  U. 
  S. 
  National 
  Museum, 
  

   and 
  by 
  Mrs. 
  OUve 
  S. 
  Tattersall 
  to 
  prepare 
  this 
  short 
  paper 
  to 
  supply 
  

   the 
  information 
  needed 
  to 
  bring 
  Dr. 
  Tattersall's 
  study 
  up 
  to 
  its 
  actual 
  

   date 
  of 
  publication. 
  I 
  wish 
  to 
  thank 
  Dr. 
  Chace 
  and 
  Mrs. 
  Tattersall 
  

   for 
  asking 
  me 
  to 
  make 
  this 
  emendation. 
  

  

  In 
  preparing 
  these 
  addenda, 
  I 
  hope 
  also 
  to 
  keep 
  the 
  seeming 
  errors, 
  

   resulting 
  from 
  the 
  long 
  delay 
  in 
  printing, 
  from 
  reflecting 
  in 
  any 
  way 
  

   on 
  the 
  excellent 
  reputation 
  of 
  Dr. 
  Tattersall 
  in 
  the 
  eyes 
  of 
  those 
  who 
  

   may 
  not 
  know 
  the 
  true 
  cause 
  of 
  the 
  omissions, 
  and 
  to 
  keep 
  these 
  

   omissions 
  from 
  confusing 
  later 
  workers, 
  especially 
  those 
  nonspecialists 
  

   who 
  may 
  not 
  be 
  in 
  a 
  position 
  to 
  investigate 
  all 
  the 
  literature 
  on 
  the 
  

   group. 
  

  

  No 
  more 
  will 
  be 
  done 
  than 
  to 
  point 
  out 
  under 
  the 
  various 
  species 
  

   the 
  additions 
  to 
  the 
  literature 
  pertinent 
  to 
  their 
  taxonomic 
  status 
  or 
  

   to 
  the 
  American 
  records. 
  Where 
  there 
  may 
  be 
  a 
  question 
  about 
  the 
  

   taxonomy 
  of 
  any 
  species, 
  it 
  wUl 
  merely 
  be 
  mentioned 
  but 
  not 
  resolved; 
  

   finally, 
  any 
  publications 
  issued 
  after 
  the 
  date 
  of 
  publication 
  of 
  Tatter- 
  

   sall's 
  work 
  will 
  not 
  be 
  reported.

  The 
  list 
  of 
  American 
  species 
  should 
  be 
  changed 
  as 
  follows: 
  

  

  Subfamily 
  Boreomysinae 
  8 
  species 
  

  

  Tribe 
  Erythropini 
  28 
  

  

  Tribe 
  Mysini 
  35 
  

  

  Subfamily 
  Mysidellinae

  To 
  the 
  fresh-water 
  species 
  of 
  mysids 
  should 
  be 
  added 
  Neomysis 
  mer- 
  

   cedis, 
  from 
  the 
  west 
  coast 
  of 
  North 
  America 
  (Banner, 
  1948, 
  pt. 
  II, 
  

   p. 
  75). 
  

  

  The 
  total 
  of 
  littoral 
  species 
  for 
  the 
  Pacific 
  coast 
  should 
  be 
  raised 
  to 
  

   32 
  and 
  Mysis 
  oculata 
  should 
  be 
  added 
  as 
  a 
  species 
  common 
  to 
  both 
  

   coasts 
  of 
  North 
  America 
  (see 
  the 
  discussion 
  under 
  that 
  species 
  below).

  In 
  table 
  1 
  the 
  number 
  of 
  west

  of 
  Acanthomysis 
  should

  To 
  the 
  list 
  of 
  deeper-water 
  species 
  found 
  only 
  off 
  the 
  continental 
  

   shelf 
  of 
  the 
  Pacific 
  slope 
  should 
  be 
  added 
  Katerythrops 
  sp. 
  and 
  Mysidella 
  

   americana. 
  

  

  To 
  the 
  list 
  of 
  pelagic 
  species 
  common 
  to 
  both 
  the 
  Atlantic 
  and 
  Pacific 
  

   coasts 
  should 
  be 
  added 
  Boreomysis 
  microps.
