A  BINOSATTRIAN  VERTEBRA  EROM  HASTINGS.  [May  1 893. 
21.  On  a  Sauropodous  Dinosaurian  Vertebra  from  the  Wealden  of 
Hastings.  By  B.  Lydekker,  Esq.,  B.A.,  F.G.S.  (Bead 
December  21st,  1892.) 
In  an  earlier  volume  of  this  Journal  Mr.  Hulke  figured  and  described 
certain  vertebrse  of  a  large  Sauropodous  Dinosaur  from  the  Wealden 
of  the  Isle  of  Wight,  under  the  name  of  Ornithopsis ,l  that  name 
having  been  substituted  for  Eucamerotus ,2  which  the  author  had 
previously  intended  to  use  on  account  of  its  being  the  earlier.  I 
have  subsequently  had  reason  to  indicate  that  the  name  Ornithopsis 
itself  must,  for  the  same  reason,  yield  to  Iloplosaurus ,3  which  was 
proposed  by  Gervais  on  the  evidence  of  a  tooth  of  the  same  animal. 
In  addition  to  Iloplosaurus  armatus  and  the  still  larger  Peloro- 
saurus  Conybeari ,  there  is  evidence  of  another  large  Sauropodous 
Dinosaur  in  the  Wealden,  now  known  as  Morosaurus  brevis 
(Owen).4  Dp  to  the  present  time  it  has,  however,  been  impossible 
to  compare  adequately  Hoplosaurus  armatus  with  Morosaurus  brevis , 
owing  to  the  circumstance  that  while  the  former  is  known  by  teeth, 
cervical  and  dorsal  vertebrse,  and  the  pelvis,  the  latter  is  mainly  re¬ 
presented  by  the  bones  of  a  forelimb  and  some  caudal  vertebrae ;  an 
imperfect  centrum  of  a  late  dorsal  vertebra  having  been  also  tenta¬ 
tively  assigned  to  it. 
Becently  Mr.  P.  Bufford,  of  Hastings,  has  sent  to  the  British 
Museum  (Bat.  Hist.)  for  identification  an  imperfect  dorsal  vertebra 
of  a  large  Sauropodous  Dinosaur  from  the  Wealden  of  Hastings, 
which  has  enabled  the  desired  comparison  to  be  made. 
I  would  observe  in  the  first  place  that  the  specimens  which  must 
be  regarded  as  the  types  of  Cetiosaurus  brevis  are  four  associated 
caudal  vertebrae  from  the  Wealden  of  Cuckfield,  bearing  the  numbers 
2544-2550  in  the  British  Museum  Begister.5  Subsequently  Prof. 
Marsh  6  applied  the  name  Morosaurus  BecJclesi  to  a  Dinosaur  repre¬ 
sented  by  the  bones  of  a  forelimb  formerly  in  the  collection  of  the 
late  Mr.  Beckles,  which  have  now  been  acquired  by  the  British 
Museum.  Still  later  I  pointed  out  that  there  was  every  probability 
that  these  limb-bones  belonged  to  Cetiosaurus  brevis ,  for  which  the 
name  Morosaurus  brevis  was  accordingly  substituted.7 
Bow,  all  these  bones  are  characterized  by  their  ochreous  colour, 
and  are  thereby  very  different  from  those  of  Hoplosaurus  from 
the  Isle  of  Wight,  which  are  blackish.  Mr.  Bufford’s  specimen  is 
likewise  of  the  same  ochreous  tint,  and  comes  probably,  therefore, 
from  the  same  bed  as  the  limb-bones  obtained  by  Mr.  Beckles.  This
