  The 
  Basals 
  of 
  Euoeniaceinid^. 
  By 
  F. 
  A. 
  Bathee, 
  Esq., 
  B.A., 
  

   F.G.S., 
  of 
  the 
  British 
  Museum 
  (Natural 
  History). 
  (Bead 
  

   April 
  3, 
  1889.) 
  

  

  In 
  the 
  course 
  of 
  my 
  paper 
  on 
  Trigonocrinus 
  * 
  I 
  had 
  occasion 
  to 
  

   refer 
  to 
  the 
  views 
  held 
  by 
  various 
  writers 
  as 
  to 
  the 
  position 
  of* 
  the 
  

   basals 
  in 
  the 
  Eugeniacrinidse. 
  As 
  the 
  question 
  was 
  then 
  gone 
  into 
  

   thoroughly, 
  and 
  as 
  the 
  occasion 
  is 
  so 
  recent, 
  it 
  is 
  unnecessary 
  to 
  

   recapitulate 
  the 
  arguments 
  there 
  employed. 
  Suffice 
  it 
  to 
  say 
  that 
  

   I 
  adopted 
  the 
  opinions 
  of 
  Prof. 
  E. 
  Beyrich 
  t 
  and 
  Prof. 
  K. 
  von 
  Zittel 
  % 
  

   in 
  preference 
  to 
  those 
  of 
  Mons. 
  P. 
  de 
  Loriol 
  § 
  on 
  the 
  one 
  hand, 
  and 
  of 
  

   Dr. 
  P. 
  H. 
  Carpenter 
  j| 
  on 
  the 
  other. 
  Dr. 
  Carpenter, 
  who 
  was 
  present 
  

   at 
  the 
  reading 
  of 
  my 
  paper, 
  and 
  joined 
  in 
  the 
  discussion, 
  was 
  not 
  

   wholly 
  convinced 
  by 
  my 
  arguments 
  ; 
  at 
  the 
  same 
  time 
  he 
  admitted 
  

   that, 
  if 
  the 
  specimens 
  alluded 
  to 
  by 
  Beyrich 
  and 
  v. 
  Zittel 
  showed 
  the 
  

   course 
  of 
  the 
  axial 
  canals 
  to 
  be 
  as 
  described 
  by 
  those 
  authors, 
  then 
  

   I 
  should 
  be 
  entirely 
  justified 
  in 
  following 
  their 
  views 
  as 
  to 
  the 
  

   basals, 
  anomalous 
  though 
  the 
  said 
  views 
  appeared 
  to 
  him 
  to 
  be. 
  

  

  I 
  had 
  already 
  spoken 
  to 
  Prof. 
  v. 
  Zittel 
  on 
  the 
  subject 
  and 
  could 
  

   not 
  doubt 
  the 
  accuracy 
  of 
  his 
  observations 
  any 
  more 
  than 
  his 
  good 
  

   faith. 
  The 
  sceptical 
  attitude, 
  however, 
  maintained 
  by 
  Dr. 
  Carpenter 
  

   in 
  all 
  his 
  discussions 
  with 
  me, 
  both 
  private 
  and 
  public, 
  induced 
  

   me 
  to 
  write 
  to 
  Prof. 
  v. 
  Zittel 
  ; 
  for 
  it 
  should 
  be 
  remembered 
  that 
  

   neither 
  Beyrich 
  nor 
  v. 
  Zittel 
  had 
  ever 
  described 
  the 
  actual 
  specimens 
  

   on 
  which 
  they 
  based 
  their 
  conclusions, 
  and 
  that 
  they 
  had 
  not 
  given 
  

   any 
  figures 
  or 
  even 
  diagrams. 
  The 
  only 
  figure 
  of 
  importance 
  in 
  this 
  

   connexion 
  which 
  I 
  could 
  find 
  was 
  that 
  given 
  by 
  Goldfuss
