  This 
  genus 
  was 
  assigned 
  to 
  the 
  subfamily 
  Fulgurinee 
  in 
  the 
  

   Turbinellidse 
  by 
  Fischer 
  in 
  1887. 
  In 
  1890 
  Dall 
  gave 
  a 
  dis- 
  

   cussion 
  of 
  the 
  known 
  species 
  at 
  that 
  time 
  and 
  assigned 
  the 
  

   genus 
  to 
  the 
  family 
  Fasciolariidse. 
  In 
  1901 
  Cossmann 
  published 
  

   probably 
  the 
  most 
  careful 
  generic 
  description 
  to 
  be 
  found 
  in 
  

   the 
  literature 
  on 
  the 
  genus 
  Busycon 
  and 
  assigned 
  it 
  to 
  the 
  sub- 
  

   family 
  Fulgurinse. 
  In 
  1903 
  Grabau 
  and 
  Shinier 
  very 
  fittingly 
  

   applied 
  the 
  family 
  name 
  Fulguridse. 
  In 
  1915 
  Dall 
  called 
  

   attention 
  to 
  the 
  ruling 
  of 
  the 
  International 
  Committee 
  on

  Nomenclature 
  and 
  revived 
  the 
  old 
  Bolten 
  name 
  Busycon, 
  but 
  

   referred 
  the 
  genus 
  to 
  the 
  family 
  Buccinidse. 
  The 
  present 
  

   paper 
  extends 
  the 
  range 
  of 
  the 
  genus 
  by 
  including 
  a 
  descrip- 
  

   tion 
  of 
  an 
  Upper 
  Cretaceous 
  species, 
  and 
  emphasizes 
  the 
  

   desirability 
  of 
  recognizing 
  the 
  family 
  rank 
  of 
  the 
  Fulguridse 
  

   for 
  the 
  fulguroid 
  group. 
  In 
  accordance 
  with 
  the 
  accepted 
  

   rules 
  of 
  nomenclature 
  this 
  should 
  be 
  the 
  family 
  Busyconidse, 
  

   as 
  Busycon 
  has 
  replaced 
  Fulgur 
  as 
  the 
  type 
  genus. 
  

  

  The 
  new 
  species 
  described 
  below 
  differs 
  from 
  its 
  congeners 
  

   sufficiently 
  to 
  form 
  the 
  type 
  of 
  a 
  new 
  subgenus 
  for 
  which 
  the 
  

   name 
  Protobusycon 
  is 
  proposed.
