Additional  remarks. — In  the  Euones  Muren,  between  Kirchen 
Bach  and  Incisa  Bach,  very  fossiliferous  strata  are  exposed ;  they 
correspond  to  bed  No.  12  (Middle  St.  Cassian)  in  the  first  column  of 
the  Table,  and  contain  the  same  fossils  as  are  found  on  Stuores 
"Wiese.  These  strata  are  (in  descending  order) : —

: a 
’  Marls,  often  ferruginous,  and  thin  layers  of  aragonite. 
G-rey  limestones  and  shales  with  irregular  surface,  sometimes  ripple- 
marked. 
Oolitic  hmestone-beds,  several  inches  thick,  containing  at  intervals 
highly  fossiliferous  layers  from  1  to  3  inches  thick 
(  Unfossiliferous  marls,  limestones,  aragonite,  etc. 
Fossiliferous,  yellowish,  oolitic  limestone,  sometimes  crowded  with  corals 
and  sponges. 
Fossiliferous  marls  and  thin-bedded  shaly  limestones. 
Thick  bed  of  limestone  in  which  alternating  layers,  fossiliferous  and 
non-fossiliferous,  maybe  distinguished. 
Marls,  etc.,  of  the  more  ashy  series  denoted  in  the  Table  as  Nos.  10 
and  11,  etc.,  containing  fewer  fossils. 
In  the  succession  of  beds  described  for  Section  1,  Nos.  13  to  15 
ire  identical  with  the  beds  of  Nos.  8  to  12,  and  these  relations 
tontinue  for  some  distance  north  and  south.  A  slight  fault  causes 
he  fossiliferous  series  to  occur  at  the  two  levels. 
From  the  fossils  which  I  carefully  collected  at  the  various  horizons 
.  classify  the  succession  of  beds  in  this  section  in  two  groups  : — 
St.  Cassian  Series  =  Nos.  15-8.1  «  T  ,, 
Wengen  Series  =  Nos.  7-1. jee  a  j  01 
The  Wengen  Series  is  continued  with  a  general  north- and-south 
trike  over  the  Incisa  Pass,  and  has  a  wide  distribution  on  the 
eights  of  Campolungo.  In  the  woods  towards  Eudort  Valley  the 
xposures  are  unfavourable,  and  I  found  few  fossils  even  in  the 
igher  slipped  portions  of  rock.  The  beds  dip  slightly  outward  from 
le  hill,  and  are  at  times  much  contorted.  The  best  exposure  of
