  A 
  circumpolar. 
  Boreal 
  Arctic 
  species, 
  usually 
  in 
  shallow 
  water. 
  

   Some 
  of 
  these 
  specimens, 
  notably 
  from 
  stations 
  5023 
  and 
  5024, 
  are 
  

   somewhat 
  more 
  compact 
  than 
  the 
  others, 
  suggesting 
  Losina-Losinsky's 
  

   variety 
  hrevicollis. 
  All 
  the 
  Albatross 
  stations 
  are 
  north 
  of 
  42° 
  (around 
  

   Hokkaido), 
  while 
  variety 
  bremcollis 
  is 
  reported 
  from 
  the 
  vicinity 
  of 
  

   Vladivostok 
  near 
  43°

  Although 
  Ohshima 
  states 
  that 
  he 
  "observed 
  one 
  specimen 
  in 
  a 
  collec- 
  

   tion 
  from 
  Sagami 
  Bay," 
  this 
  species 
  is 
  not 
  represented 
  in 
  these 
  collec- 
  

   tions, 
  and 
  Ohshima's 
  record 
  may 
  be 
  a 
  mistake, 
  or 
  it 
  may 
  be 
  confused 
  

   with 
  N. 
  japonicwn. 
  Nymphon 
  macruirh 
  is 
  not 
  known 
  to 
  be 
  circum- 
  

   polar, 
  but 
  is 
  found 
  in 
  the 
  North 
  Atlantic 
  as 
  far 
  south 
  as 
  Cape 
  Hatteras 
  

   and 
  in 
  the 
  Barents 
  Sea.

  Losina-Losinsky's 
  (1929) 
  proposal 
  to 
  use 
  this 
  name 
  as 
  a 
  group 
  

   designation 
  for 
  several 
  closely 
  related 
  forms 
  (which 
  are 
  arranged 
  

   in 
  a 
  bewildering 
  array 
  of 
  varieties, 
  subspecies, 
  and 
  forms) 
  is 
  un- 
  

   fortunate. 
  According 
  to 
  the 
  synonymy 
  by 
  Stephensen 
  this 
  name 
  be- 
  

   longs 
  to 
  the 
  species 
  described 
  and 
  figured 
  by 
  Sars 
  as 
  Nymphon 
  gracile, 
  

   and 
  the 
  taxonomic 
  group 
  proposed 
  by 
  Losina-Losinsky 
  does 
  not 
  in- 
  

   chide 
  this 
  species 
  at 
  all. 
  

  

  The 
  specimen 
  for 
  which 
  Hilton 
  has 
  proposed 
  the 
  name 
  microcoUis 
  

   agrees 
  closely 
  with 
  Sars's 
  figure, 
  and 
  is 
  readily 
  separable 
  from 
  Nym- 
  

   phon 
  brevitarse, 
  wliich 
  Losina-Losinsky 
  reduced 
  to 
  subspecific 
  rank 
  

   under 
  N. 
  brevirostre, 
  and 
  which 
  I 
  suggested 
  (1943a, 
  p. 
  89) 
  might 
  be 
  

   the 
  species 
  identified 
  by 
  Hilton 
  as 
  N, 
  gracile 
  Leach. 
  These 
  various 
  

   names 
  have 
  become 
  so 
  confused 
  that 
  it 
  is 
  almost 
  hopeless 
  to 
  be 
  

   certain 
  of 
  an 
  identification. 
  Thus 
  one 
  of 
  the 
  purposes 
  of 
  the 
  binomial
