  Tattersall 
  and 
  Banner 
  arrived 
  independently 
  at 
  the 
  same 
  conclusion 
  

   that 
  N. 
  franciscorum 
  Holmes 
  is 
  a 
  synonym 
  of 
  N. 
  rayii. 
  The 
  records 
  

   given 
  by 
  Banner 
  (1948, 
  pt.

  p. 
  78) 
  augment 
  those 
  given 
  by 
  Tattersall.

  Under 
  this 
  species 
  should 
  be 
  added 
  the 
  observations 
  that 
  it 
  pene- 
  

   trates 
  and 
  lives 
  in 
  fresh-water 
  lakes, 
  such 
  as 
  Lake

  near 
  

   Seattle 
  (Banner,

  Additional 
  records 
  of 
  this 
  species 
  from 
  Washington 
  and 
  British 
  

   Columbia 
  have

  Observations 
  have 
  shown 
  that 
  this 
  species 
  exhibits 
  great 
  variation 
  

   on 
  many 
  points, 
  especiall}^ 
  in 
  the 
  sculpturing 
  of 
  the 
  abdomen 
  (Banner, 
  

   1948, 
  pt. 
  II, 
  pp. 
  97-101). 
  The 
  records 
  have 
  extended 
  the 
  range 
  of 
  

   the 
  species 
  from 
  Washington 
  to 
  southern 
  California.

  The 
  known 
  range 
  of 
  this 
  species 
  has 
  been 
  extended 
  to 
  include 
  the 
  

   inland 
  waters 
  of 
  Washington 
  (Banner,

  Tattersall, 
  in 
  an 
  earlier 
  publication 
  (1933, 
  p. 
  94) 
  and 
  again 
  in 
  this 
  

   publication, 
  states 
  that 
  he 
  believes 
  the 
  exopod 
  of 
  the 
  fourth 
  pleopods 
  of 
  

   the 
  male 
  to 
  be 
  of 
  three 
  articles; 
  this 
  appendage 
  was 
  found 
  to 
  be 
  com- 
  

   posed 
  of 
  a 
  single 
  article 
  (Banner, 
  1948, 
  pt. 
  II. 
  p. 
  89). 
  In 
  addition, 
  the 
  

   records 
  cited 
  have 
  extended 
  the 
  range 
  southward 
  into 
  Washington 
  and 
  

   also 
  give 
  another 
  Alaskan 
  record.

  To 
  the 
  genus 
  Acanthomysis 
  should 
  be 
  added 
  two 
  new 
  species 
  

   described 
  from 
  the 
  northwestern 
  coast 
  of 
  America, 
  A. 
  nephrophthalma 
  

   Banner

  A.

  (1948,

  and 
  an 
  unnamed 
  

   specimen 
  from 
  Alaska, 
  Acanthomysis 
  sp.

  (1948,

  In 
  an 
  additional 
  record 
  for 
  this 
  species 
  from 
  Washington 
  a 
  new 
  

   location 
  has 
  been 
  given 
  (Banner,

  To 
  Tattersall's 
  list 
  of 
  genera 
  and 
  species 
  occurring 
  in 
  the 
  waters 
  of 
  

   the 
  Americas 
  should 
  be 
  added 
  Mysidella 
  americana 
  Banner 
  (1948, 
  

   pt. 
  II, 
  p. 
  109), 
  a 
  member 
  of 
  the 
  last 
  subfamily 
  of 
  the 
  Mysidae, 
  the 
  

   Mysidellinae, 
  which 
  was 
  described 
  from 
  British 
  Columbia 
  and 
  which 
  

   is 
  the 
  only 
  record 
  of 
  the 
  subfamily 
  from 
  American 
  waters. 
  

  

  ' 
  I 
  plan 
  to 
  discuss 
  the 
  validity 
  of 
  this 
  species 
  in 
  a 
  forthcoming 
  publication.
