  Oldroyd 
  published 
  a 
  copy 
  of 
  Conrad's 
  original 
  description. 
  As 
  has 
  been 
  pointed 
  out 
  by 
  

   several 
  authors 
  Conrad's 
  name 
  is 
  preoccupied 
  by 
  his 
  own 
  earlier 
  naming. 
  The 
  next 
  name 
  

   available 
  is 
  that 
  of 
  Carpenter 
  (1855, 
  p. 
  230) 
  ; 
  hence 
  the 
  inclusion 
  of 
  the 
  species 
  in 
  this 
  report.
