  The 
  specific 
  name 
  of 
  this 
  Panama 
  species 
  was 
  changed 
  by 
  Carpenter, 
  because 
  he 
  thought 
  

   the 
  Murex 
  muricatiis 
  Montagu 
  was 
  congeneric 
  (secondary 
  homonym). 
  Oldroyd 
  (1929, 
  p. 
  99) 
  

   renamed 
  shells 
  CoralUophila 
  Oldroydi 
  from 
  Catalina 
  Island 
  which 
  had 
  gone 
  under 
  Car- 
  

   penter's 
  name. 
  Burch 
  enumerated 
  the 
  factors 
  in 
  regard 
  to 
  the 
  identification 
  of 
  Oldroyd's 
  and 
  

   Hinds' 
  (original) 
  species. 
  He 
  believed 
  that 
  they 
  are 
  distinct 
  and 
  extended 
  the 
  range 
  of 
  

   L. 
  costata 
  hirvdsii 
  from 
  Point 
  Conception 
  to 
  Panama. 
  The 
  type 
  of 
  the 
  species 
  is 
  a 
  shell 
  from 
  

   the 
  "Voyage 
  of 
  the 
  Sulphur" 
  and 
  not 
  one 
  of 
  Carpenter's. 
  The 
  name 
  is 
  included 
  here 
  only 
  to 
  

   explain
