30  MISS  OILYGIE  ON  THE  WEN  GEN  AND  [Feb.  1 893, 
Fig.  6  (p.  29)  has  chiefly  a  tectonic  interest,  and  will  be  referred 
to  under  Part  YIII.  of  this  paper  (p.  67). 
The  strata  on  the  Falzarego  Alpe,  which  conformably  underlie  the 
Schlern  Dolomite  of  Lagazuoi,  and  extend  down  to  the  Costeana 
stream,  contain  the  typical  St.  Cassian  fossils ;  and  the  series  may 
be  traced  farther  west,  conformably  underlying  the  Schlern  Dolomite 
on  both  sides  of  the  descent  from  the  Tra  i  Sassi  Pass  towards  Val- 
parola.  The  same  beds,  containing  an  identical  fauna,  are  exposed 
beside  the  Raibl  Peds  and  the  Dachstein  Dolomite  north  of  Sett 
Sass,  and  appear  with  their  greatest  outcrop  freely  exposed  on  the 
Stuores  "Wiese,  Prelongei,  and  the  Forcella  di  Sett  Sass. 
Fig.  7  may  be  compared  with  fig.  8 ;  in  the  latter  a  conformable 
succession  of  the  fossiliferous  strata  is  shown  from  the  Majorera 
slope,  at  about  the  1800-metre  contour,  to  the  meadows  at  the 
base  of  Crepa,  between  the  1400  and  1500-metre  contours.  The 
beds  strike  north  and  south,  and  dip  not  more  than  10°  west.

(Below  the  1800-metre  contour  a  hard,  light  grey  lime¬ 
stone-rock,  sometimes  slightly  dolomitic,  containing 
spines  of  Cidaris  dorsata,  and  looking  like  the  Cipit 
Limestone  of  lower  horizons.  In  parts  of  the  rock, 
«{  bedding  is  more  marked,  and  fossils  weather  out.  Ci- 
darid  spines,  small  corals  and  gasteropods  were  found. 
Shaly  limestone-beds,  breccias  of  tuff  and  limestone, 
highly  fossiliferous.  This  rock  is  often  coloured  dark 
v  red  by  interstitial  ferruginous  earth.
