von  der  Lintb1  in  1854  tells  bow  be  and  others  convinced  them¬ 
selves  that  the  Eaibl  strata  (‘  Schiefer  n.  Sandstein ')  of  the  Torarl- 
berg  and  of  Northern  Tyrol  were  of  Keuper  and  not  of  Liassic  age  : 
that  similar  strata  with  Cardiia  crenata ,  Goldf.,  occurred  near  Hall, 
in  Lavatsch  Thai,  and  in  several  other  localities,  in  close  association 
with  strata  containing  j Halobia  Lommeli ,  Wissm.  ;  that  these  repre¬ 
sented  without  donbt  true  St.  Cassian  strata,  and  must  be  regarded 
as  a  marine  equivalent  of  a  part  of  the  Keuper. 
In  a  paper  written  by  Merian 2  from  Basel,  a  series  of  greenish- 
grey  sandstones  with  plants,  now  recognized  as  Baibl  strata,  was 
included  with  dark-grey  or  black  fossiliferous  limestones,  and  beds 
"with  Halohia  Lommeli ,  Wissm.,  as  4 5  Lower  St.  Cassian  Formation’ 
below  the  horizon  now  called  *  Hauptdolomit.’ 
Following  a  preliminary  contribution  made  by  von  Hauer  3  in 
1855,  Foetterle4  gave  in  1S56  subdivisions  of  the  Baibl  strata 
from  observations  which  he  and  the  first-named  author  had  made 
in  the  country  from  Baibl  to  Hogna.  The  succession  he  re¬ 
garded  as  : — 
f  Uppermost  horizon. 
Marly  shales  and  limestones :  characteristic  fossils — 
Astarte  {Corbula')  Lost  horn  i:  Bone,  sp.,  Ostrcsa  monfis- 
Baibl  Strata.  {  caprilis,  Jvlipst.,  etc. 
Marls  with  Myophoria  Kefersteini,  Goldf.,  sp. 
Bituminous  shales  with  plant-  and  fish-remains,  forming 
[_  the  lowest  horizon. 
"While  he  remarked  that  the  fossils,  even  up  to  the  Corbula 
Roslhorui- beds,  much  resembled  the  St.  Cassian  fossils,  he  gave 
to  the  whole  group  the  name  of  4  Baibl  strata,’  and  defined  them 
as  the  series  of  beds  above  the  Hallstadter  Kalk  ( =  Wetterstein 
Balk  of  Giimbel)  and  below  the  Bachstein  Kalk  (  =  Hauptdolomit 
of  Gumbel) . 
In  the  following  year,  Hauer ;  gave  a  complete  description, 
with  plates,  of  the  moBusca  of  the  Baibl  strata  as  exposed  at 
Baibl,  at  Agordo  in  Lombardy,  at  Schlern,  and  at  other  places. 
The  fossils  of  the  lowest  horizon  of  Baibl  strata  in  Foetterle’s 
subdivision  were  handled  by  Bronn.6  In  reviewing  Bronn’s  work 
and  combining  the  results  of  previous  research,  Hauer  came
