  THE 
  VERTEBRATE 
  FAUNA 
  OF 
  "DEE." 
  

  

  and 
  Spotted 
  Rays 
  of 
  Yarrell 
  ; 
  while 
  it 
  is 
  the 
  Cuckoo 
  Ray 
  of 
  

   Couch, 
  with 
  the 
  scientific 
  name 
  of 
  miraletus. 
  Nor 
  are 
  the 
  

   figures 
  given 
  of 
  the 
  species 
  to 
  be 
  regarded 
  as 
  more 
  satisfactory. 
  

   No 
  two 
  of 
  them 
  are 
  alike, 
  nor 
  are 
  they 
  in 
  form 
  like 
  the 
  fish 
  

   they 
  are 
  intended 
  to 
  represent. 
  Day's 
  figure 
  of 
  B. 
  circularis 
  

   would 
  pass 
  for 
  B. 
  radula, 
  but 
  it 
  is 
  in 
  no 
  way 
  like 
  the 
  true 
  

   circularis. 
  Couch's 
  uncoloured 
  figure 
  of 
  circularis, 
  whksh 
  he 
  

   names 
  the 
  Cuckoo 
  Ray, 
  is 
  good 
  so 
  far 
  as 
  form 
  goes 
  ; 
  but 
  the 
  

   spinulation 
  is 
  not 
  correct. 
  Besides, 
  he 
  describes 
  the 
  figure 
  as 
  

   being 
  that 
  of 
  a 
  male; 
  if 
  it 
  is 
  so, 
  he 
  has 
  omitted 
  to 
  show 
  the 
  

   claspers. 
  The 
  coloured 
  figure 
  of 
  his 
  Cuckoo 
  Ray 
  is 
  not 
  the 
  

   proper 
  shape, 
  as 
  may 
  be 
  seen 
  by 
  comparing 
  it 
  with 
  the 
  

   uncoloured 
  one 
  at 
  p. 
  114, 
  vol. 
  i. 
  

  

  Yarrell's 
  figure 
  of 
  circularis, 
  which 
  he 
  designates 
  the 
  

   Homelyn 
  Ray, 
  is, 
  so 
  far 
  as 
  form 
  goes, 
  the 
  most 
  correct 
  of 
  

   the 
  lot 
  ; 
  but 
  he 
  shows 
  nothing 
  of 
  the 
  spinulation 
  on 
  the 
  

   " 
  wings." 
  His 
  figure 
  and 
  description 
  of 
  B. 
  radula, 
  as 
  

   given 
  in 
  his 
  supplement 
  to 
  British 
  Fishes, 
  published 
  in 
  1839, 
  

   p. 
  19, 
  is 
  merely 
  a 
  reproduction 
  of 
  that 
  given 
  by 
  Couch 
  in 
  

   the 
  Magazine 
  of 
  Nat. 
  Hist., 
  New 
  Series, 
  vol. 
  xi., 
  and 
  is 
  intended 
  

   for 
  a 
  female, 
  but 
  is 
  in 
  outline 
  more 
  nearly 
  that 
  of 
  a 
  male, 
  

   the 
  anterior 
  edges 
  of 
  the 
  female 
  being 
  rounded 
  instead 
  of 
  

   being 
  hollowed 
  out 
  as 
  his 
  figure 
  represents 
  it. 
  

  

  Beneath 
  the 
  figure 
  Mr. 
  Yarrell

  Yarrell 
  further 
  remarks 
  : 
  " 
  The 
  close 
  accordance 
  of 
  the 
  

   figure 
  and 
  description 
  of 
  this 
  fish 
  by 
  Mr. 
  Couch 
  to 
  the 
  figure 
  

   and 
  descriptions 
  of 
  Baia 
  radula 
  of 
  the 
  authors 
  here 
  quoted 
  

   leaves 
  little 
  room 
  to 
  doubt 
  but 
  that 
  they 
  refer 
  to 
  the 
  same 
  

   species, 
  and 
  I 
  include 
  the 
  fish, 
  therefore, 
  as 
  here 
  given, 
  on 
  

   Mr. 
  Couch's 
  authority." 
  

  

  As 
  will 
  be 
  seen 
  from 
  the 
  above, 
  Day 
  puts 
  the 
  Cuckoo 
  

   Ray 
  and 
  Sandy 
  Ray 
  of 
  Couch 
  as 
  the 
  same 
  species. 
  This 
  

   he 
  was 
  certainly 
  not 
  warranted 
  in 
  doing, 
  for 
  the 
  following 
  

   reasons. 
  First, 
  B. 
  radula 
  is 
  an 
  abyssal 
  form, 
  while 
  B. 
  circularis
