  from 
  

   Laguna 
  Fria, 
  Lake 
  Nahuel-Huapi, 
  is 
  referred 
  to 
  this 
  genus. 
  The 
  

   generic 
  diagnosis 
  of 
  this 
  genus 
  is 
  based 
  on 
  numerous 
  lots 
  in 
  the 
  

   National 
  collection 
  including 
  several 
  species, 
  among 
  which 
  are 
  numer- 
  

   ous 
  specimens 
  of 
  A. 
  regia 
  (Humboldt), 
  all 
  from 
  Peru, 
  Chile, 
  Argen- 
  

   tina, 
  including 
  the 
  Falkland 
  Islands. 
  A 
  count 
  made 
  on 
  A. 
  nigricans 
  

   from 
  the 
  Falkland 
  Islands 
  revealed 
  28 
  + 
  30 
  vertebrae. 
  

  

  The 
  following 
  species 
  as 
  recognized 
  by 
  Jordan 
  and 
  Hubbs 
  are 
  

   referred 
  to 
  this 
  genus: 
  A. 
  hatcheri 
  (Eigenmann) 
  ; 
  A. 
  regia 
  (Hum- 
  

   boldt) 
  ; 
  A. 
  laticlavia 
  (Cuvier 
  and 
  Valenciennes) 
  ;

  Upon 
  writing 
  to 
  Dr. 
  L. 
  Bertin, 
  Museum 
  National 
  d'Histoire 
  Natu- 
  

   relle, 
  Paris, 
  concerning 
  the 
  types 
  of 
  Atherina 
  jacksoniana 
  Quoy 
  and 
  

   Gaimard, 
  I 
  received 
  the 
  following 
  information, 
  which 
  I 
  greatly 
  

   appreciate 
  : 
  There 
  are 
  four 
  types 
  measuring 
  62.5 
  (57), 
  71 
  (63), 
  73 
  (63), 
  

   and 
  120.5 
  (105) 
  mm., 
  in 
  total 
  length, 
  the 
  standard 
  length 
  given 
  in 
  

   parentheses 
  ; 
  origin 
  of 
  first 
  dorsal 
  fin 
  equidistant 
  between 
  tip 
  of 
  snout 
  

   and 
  midbase 
  of 
  caudal 
  fin 
  ; 
  anus 
  just 
  in 
  front 
  of 
  anal-fin 
  origin 
  ; 
  origin 
  

   of 
  first 
  dorsal 
  in 
  front 
  of 
  anus 
  ; 
  the 
  latter 
  about 
  under 
  rear 
  base 
  of 
  this 
  

   fin; 
  body 
  cavity 
  not 
  passing 
  anal 
  origin; 
  ascending 
  premaxillary 
  

   process 
  triangular 
  ; 
  premaxillary 
  protractile 
  ; 
  no 
  sheath 
  of 
  scales 
  now 
  

   present 
  on 
  bases 
  of 
  dorsal 
  or 
  anal 
  fins 
  ; 
  rays 
  of 
  first 
  dorsal 
  7, 
  second 
  

   dorsal 
  12, 
  anal 
  19,

  Gilbert 
  P. 
  Whitley 
  (Proc. 
  Linn. 
  Soc. 
  New 
  South 
  Wales, 
  vol. 
  68, 
  

   pp. 
  136-137, 
  fig. 
  10, 
  No. 
  2, 
  1943) 
  redescribes 
  and 
  figures 
  Atherina 
  

   jacksoniana 
  Quoy 
  and 
  Gaimard 
  after 
  examining 
  the 
  types 
  at 
  Paris. 
  

   He 
  states, 
  "This 
  species 
  described 
  from 
  'Port 
  Jackson' 
  by 
  Quoy 
  and 
  

   Gaimard 
  in 
  1825 
  has 
  puzzled 
  all 
  later 
  workers 
  on 
  Australian 
  fishes 
  

   because 
  none 
  of 
  our 
  Atherines 
  has 
  18 
  anal 
  rays 
  or 
  agrees 
  in 
  other 
  

   particulars." 
  Whitley 
  states 
  there 
  are: 
  Two 
  rows 
  of 
  cheek 
  scales; 
  

   mandibular 
  rami 
  elevated 
  ; 
  teeth 
  distinct 
  ; 
  gill 
  rakers 
  slender 
  and 
  num- 
  

   erous 
  ; 
  scales 
  80 
  ; 
  five 
  rows 
  of 
  scales 
  over 
  lateral 
  band 
  ; 
  vent 
  well 
  behind 
  

   tips 
  of 
  ventral 
  fins 
  and 
  well 
  before 
  anal; 
  pectorals 
  with 
  dusky 
  tips; 
  

   a 
  broad 
  silvery 
  lateral 
  band 
  ; 
  about 
  12 
  or 
  13 
  dorsal 
  and 
  18 
  anal 
  rays. 
  

   Both 
  AVliitley 
  and 
  Bertin 
  agree 
  that 
  there 
  are 
  12 
  or 
  13 
  rays 
  in 
  the 
  

   second 
  dorsal 
  and 
  18 
  or 
  19 
  anal 
  rays. 
  Bertin 
  in 
  giving 
  the 
  vertebrae 
  

   28 
  + 
  31 
  = 
  59 
  conclusively 
  casts 
  this 
  species 
  out 
  of 
  most 
  of 
  the 
  other 
  

   genera 
  of 
  Atherinidae, 
  except 
  Austromenidia. 
  In 
  fact, 
  none 
  of 
  the 
  

   characters 
  such 
  as 
  80 
  scales, 
  protractile 
  premaxillaries, 
  origin 
  or 
  in- 
  

   sertion 
  of 
  all 
  fins, 
  position 
  of 
  anus, 
  and 
  especially 
  the 
  body 
  cavity 
  

   ending 
  in 
  front 
  of 
  the 
  anal 
  fin 
  origin, 
  given 
  by 
  Whitley 
  or 
  by 
  Bertin 
  

   disagree 
  with 
  that 
  South 
  American 
  genus.
