  Family 
  PALLENIDAE 
  Wilson, 
  1878 
  

  

  The 
  author 
  agrees 
  with 
  Marcus 
  (1940, 
  p. 
  128) 
  that 
  it 
  is 
  not 
  necessary 
  

   to 
  change 
  this 
  family 
  name 
  although 
  PalleTie^ 
  the 
  type 
  genus, 
  is 
  a 
  

   preoccupied 
  name 
  and 
  has 
  been 
  replaced 
  by 
  CallipaTlene 
  Flynn 
  (1929) 
  . 
  

   This 
  usage 
  has 
  been 
  explained 
  in 
  a 
  previous 
  paper 
  (1948, 
  pp. 
  199-201) 
  

   and 
  finds 
  support 
  in 
  the 
  views 
  expressed 
  by 
  Berg 
  in 
  his 
  "Classification 
  

   of 
  Fishes" 
  (1947, 
  p. 
  354), 
  who 
  prefers 
  the 
  family 
  names 
  that 
  have 
  

   received 
  wide 
  usage 
  in 
  ichthyology. 
  

  

  The 
  Pallenidae 
  are 
  represented 
  in 
  Japanese 
  waters 
  by 
  two 
  species 
  of 
  

   Callipallene, 
  four 
  of 
  Pallenopsis, 
  and 
  one 
  of 
  Propallene. 
  Loman 
  

   (1911, 
  p. 
  13) 
  reported 
  a 
  "Pallenopsis 
  n. 
  sp?" 
  from 
  Sagami 
  Bay, 
  which 
  

   unfortunately 
  was 
  not 
  figured. 
  He 
  remarked 
  upon 
  its 
  similarity 
  to 
  

   Pallenopsis 
  -fiuminensis^ 
  and 
  it 
  evidently 
  represents 
  still 
  another 
  species 
  

   of 
  this 
  genus 
  in 
  Japanese 
  waters, 
  but 
  it 
  is 
  probably 
  not 
  identifiable 
  

   with 
  P. 
  fluTninensis. 
  

  

  The 
  interesting 
  little 
  Decachela 
  discata^ 
  described 
  from 
  Pacific 
  

   Grove 
  by 
  Hilton 
  (1942c) 
  was 
  taken 
  by 
  the 
  Albatross 
  west 
  of 
  Hokkaido. 
  

   It 
  does 
  not, 
  in 
  my 
  opinion, 
  deserve 
  unique 
  family 
  status, 
  although 
  its 
  

   structure 
  suggests 
  a 
  transition 
  between 
  the 
  Pallenidae 
  and 
  Tanystyl- 
  

   idae. 
  Its 
  oviger 
  is 
  of 
  the 
  typical 
  pallenid 
  type. 
  

  

  Genus 
  CALLIPALLENE 
  Flynn, 
  1929 
  

  

  Represented 
  in 
  Japanese 
  waters 
  by 
  Callipallene 
  amaxana 
  (Oh- 
  

   shima), 
  taken 
  in 
  pelagic 
  tows 
  at 
  night, 
  and 
  by 
  C. 
  duhiosa^ 
  which 
  may 
  

   be 
  closely 
  related 
  to 
  C. 
  novo-zealam.dae 
  (Thomson). 
  Callipallene 
  

   amaxana 
  differs 
  from 
  the 
  latter 
  species 
  in 
  having 
  no 
  auxiliary 
  claws.
