  then 
  the

  the

   furthest

  To 
  the 
  species 
  of 
  the 
  genus 
  should 
  be 
  added 
  Katerythrops 
  sp. 
  

   Barmer 
  (1948, 
  pt. 
  I, 
  p. 
  379), 
  which 
  is 
  the 
  only 
  record 
  of 
  the 
  genus 
  in 
  

   the 
  Pacific.

  Tattersall 
  states 
  that 
  his 
  specimens 
  from 
  Bermuda 
  are 
  the 
  only 
  ones 
  

   known 
  save 
  the 
  type; 
  however, 
  Nouvel 
  (1943, 
  p. 
  75) 
  has 
  recorded 
  

   from 
  the 
  Azores 
  a 
  damaged 
  specimen 
  probably 
  of 
  this 
  species.

  To 
  Tattersall's 
  record 
  of 
  this 
  species 
  from 
  Alaska 
  should 
  be 
  added 
  

   the 
  two 
  records 
  from

  and 
  one 
  record 
  from 
  British

  To 
  the 
  west 
  coast 
  records 
  of 
  this 
  species 
  should 
  be 
  added 
  the 
  

   records

  (Banner,

  This 
  genus 
  should 
  be 
  cancelled 
  as 
  an 
  immature 
  stage 
  of 
  Caesar 
  amy 
  sis; 
  

   the 
  worth 
  of 
  the 
  species 
  could 
  not 
  be 
  determined 
  because 
  of 
  the 
  

   immaturity 
  of 
  the 
  specimen 
  described 
  (Banner, 
  1948, 
  pt. 
  I, 
  p. 
  389). 
  

  

  To 
  Tattersall's 
  account 
  of 
  American 
  mysids, 
  Caesaromysis 
  vanclevei 
  

   Banner 
  (loc. 
  cit.,) 
  should 
  be 
  added 
  here, 
  with 
  its 
  records 
  from 
  off 
  

   Oregon 
  to 
  off 
  Alaska.

  Inusilatomysis 
  serrata 
  Tattersall 
  

  

  To 
  this 
  species 
  should 
  be 
  added 
  the 
  reference 
  Inusilatomysis 
  sp. 
  

   Banner 
  (1948, 
  pt. 
  II, 
  p. 
  67), 
  which 
  is 
  apparently 
  the 
  same 
  species 
  as 
  

   Tattersall's 
  I. 
  serrata. 
  One 
  major 
  difference 
  between 
  the 
  two 
  sets 
  of 
  

   specimens 
  is 
  in 
  the 
  depth 
  of 
  the 
  terminal 
  cleft 
  of 
  the 
  telson, 
  which 
  is 
  

   one-eighth 
  the 
  length 
  of 
  the 
  telson 
  in 
  Tattersall's 
  specimens 
  and 
  one- 
  

   third 
  the 
  length 
  in 
  mine; 
  however, 
  this 
  may 
  well 
  be 
  a 
  growth 
  difference 
  

   and 
  the 
  two 
  groups 
  of 
  specimens 
  are 
  probably 
  the 
  same 
  species. 
  

  

  If 
  they 
  are 
  the 
  same, 
  then 
  the 
  records 
  of 
  Inusilatomysis 
  sp. 
  from 
  off 
  

   British 
  Columbia 
  should 
  be 
  added 
  to 
  Tattersall's 
  record 
  from 
  the 
  

   Bering 
  Sea.

  To 
  the 
  list 
  of 
  sj^nonyms 
  of 
  this 
  species 
  should 
  be 
  added 
  Pugetomysis 
  

   litoralis 
  Banner 
  (1948, 
  pt. 
  II, 
  p. 
  104), 
  and 
  the 
  range 
  of 
  the 
  species 
  in 
  

   the 
  Pacific 
  should 
  be 
  extended 
  to 
  include 
  the 
  waters 
  of 
  Washington.^

  plan
