THE  WENGEN  AND  ST.  CASSIAN  STRATA. 
[Feb.  1893. 
the  western  side  have  given  way  in  a  number  of  places,  although  no 
such  extensive  landslip  has  occurred  as  on  Abtey  Muren.  These 
beds  are  continued  westward  and  underlie  conformably  the  Schlern 
Dolomite  of  Zwischenkofl.  (See  p.  65  for  further  notes  on  this

Cortina  d’Ampezzo  {Map  B). 
The  district  of  Ampezzo  has  occupied  a  less  important  place  in 
the  older  literature  than  Schlern  and  the  Seisser  Alpe  or  St.  Cassian. 
Loretz,  who  first  made  known  the  fauna  of  the  Falzarego  Yalley, 
Misurina,  and  Seeland  Yalley,  laid  the  foundation  of  our  knowledge 
of  the  Ampezzo  dolomites ;  and  the  work  of  Hoernes  in  co-operation 
with  Mojsisovics  materially  advanced  the  geology  of  the  district. 
The  meadows  and  slopes  west  of  Cortina  d’Ampezzo  proved  of 
unusual  interest  for  the  study  of  St.  Cassian  strata,  and  I  spent 
several  days  in  collecting  the  fossils  at  various  horizons.  The 
localities  where  the  fossils  weather  out  of  the  beds  in  any  consider¬ 
able  number  are : — 
(1)  On  the  hill  above  Bomerlo. 
(2)  Below  the  Majorera  ridge,  in  the  stream-sources  and  the 
exposed  slips  of  thick  series  of  beds,  facing  Crepa. 
(3)  Among  the  wooded  slopes  of  Boscatto  e  Fratta,  from  the 
highest  beds  below  the  rocks  of  Tofana  to  the  Costeana 
stream  in  the  valley. 
(4)  South  of  the  Costeana  stream,  in  a  series  of  strips  along 
its  southern  bank,  eastward  from  Pec  di  Palu. 
(5)  West  of  Ospizio  in  Falzarego,  in  marls  and  limestones  con¬ 
formably  underlying  the  dolomite-rock  of  Lagazuoi.
