  Echinoidea," 
  I 
  directed 
  attention 
  to 
  the 
  marked 
  discrepancies 
  which 
  

   obtained 
  between 
  the 
  descriptions 
  given 
  by 
  Louis 
  and 
  Alexander 
  

   Agassiz 
  respectively 
  of 
  the 
  species 
  known 
  as 
  JS. 
  globator. 
  I 
  then 
  

   figured 
  and 
  gave 
  careful 
  descriptions 
  of 
  the 
  tests 
  of 
  two 
  forms 
  

   which 
  I 
  distinguished 
  as 
  form 
  a 
  and 
  form 
  /3. 
  I 
  adopted 
  that 
  course 
  

   in 
  the 
  hope 
  that 
  Prof. 
  Alexander 
  Agassiz 
  would 
  explain 
  the 
  reasons 
  

   which 
  had 
  led 
  him 
  to 
  omit 
  any 
  notice 
  of 
  the 
  species 
  referred 
  to 
  by 
  

   his 
  father. 
  In 
  the 
  'Challenger' 
  lieport 
  the 
  species 
  is 
  merely 
  

   recorded, 
  and 
  reference 
  made 
  to 
  the 
  ' 
  Catal. 
  Eaisonne' 
  of 
  Agassiz 
  and 
  

   Desor 
  ; 
  fortunately 
  the 
  specimens 
  are 
  uow 
  in 
  the 
  liritish 
  Museum 
  

   collection, 
  and 
  an 
  inspection 
  of 
  them 
  is, 
  of 
  course, 
  siifficient 
  to 
  show 
  

   the 
  characters 
  of 
  the 
  form 
  which 
  Mr. 
  Alex. 
  Agassiz 
  looks 
  upon 
  as 
  

   being 
  S. 
  globator. 
  I 
  lind 
  them 
  to 
  be 
  examples 
  of 
  what 
  I 
  have 
  

   called 
  form 
  a, 
  or, 
  in 
  other 
  words, 
  they 
  are 
  not 
  representatives 
  of 
  

   L. 
  Agassiz's 
  species 
  gJohator. 
  

  

  As 
  the 
  species 
  reappears 
  in 
  the 
  ' 
  Alert 
  ' 
  collection, 
  it 
  has 
  been 
  

   necessary 
  to 
  direct 
  attention 
  to 
  the 
  various 
  points 
  and 
  to 
  propose 
  

   a 
  name 
  for 
  the 
  species. 
  No 
  appellation 
  will, 
  I 
  think, 
  be 
  more 
  suit- 
  

   able 
  than 
  that 
  of 
  alexandri 
  ; 
  and, 
  at 
  the 
  time 
  of 
  giving 
  a 
  definite 
  

   name, 
  one 
  is 
  also 
  able 
  to 
  have 
  the 
  pleasure 
  of 
  adding 
  a 
  definite 
  

   locality.
