[Feb. 1893, 
ascends  on  the  opposite  side  to  the  Gardenazza  massif  at  a  level 
of  about  6200  feet.  In  the  line  of  section  the  Gardenazza  Berg 
does  not  reach  a  greater  height  than  7  600  feet.1 
Section  4  (see  p.  26). 
A.  Gardexazza  Slope. 
Schlern  Dolomite. 
A  certain  portion  of  marly  beds  almost  entirely  covered 
by  the  dolomite-blocks  from  above. 
Shaly  thin-bedded  limestones,  with  interstratified  thick 
beds  of  fossiliferous  limestone  (the  fossils  are  typical 
‘  Stuores  ’  St.  Cassian). 
Beds  of  dark  blue  limestone  with  calcite-veins,  less  fossili¬ 
ferous  (about  the  1740  met.  contour-line). 
Ashy  shales,  and  beds  of  tuff.  (Sometimes  fossils  occur 
in  the  shales  ;  plant-remains  are  very  frequent.) 
Oolitic  limestone-beds,  especially  full  of  corals  and 
enerinites  ( Encrinus  cassiams,  Laube),  various  sponges 
and  cidarid  spines. 
Grey  shaly  limestones  and  dark  shales  at  the  1600 
met.  contour. 
Numerous  well-preserved  specimens  of  Posidonomya 
wengensis  and  of  the  previously  mentioned  small 
variety  of  Tosidonomya  (sp.  ?) ;  Trachyceras  fur  cat  urn, 
Miinst.,  1  specimen.  Several  ammonites  were  found, 
but  not  in  good  preservation. 
Rough  marls  and  limestones,  with  plant-remains  and 
unrecognizable  fossils  on  the  weathered  surface.  Some 
of  these  were  cidarid  spines. 
A  series  of  ashy  grits  and  sandy  rocks,  brown  earthy 
tuffs,  and  impure  limestones ;  not  well  exposed, 
except  in  the  course  of  the  Gader  stream  below 
St.  Leonhardt  (Abtey). 
The  St.  Cassian  Beds  in  this  section  strike  through  the  Abtey 
4  Muren  ’  towards  Pescol,  where  the  characteristic  fossils  are  found 
both  lying  free  and  in  the  hard  limestone-rock.

f  ‘  Heiligkreuz  Schickten’  2  (according  to  the  original 
application  of  the  name  by  Wissmann)  =  grey,  tbinly- 
bedded  shaly  limestones  with  ( Natica )  Ptychostoma

1  I  give  these  heights  in  the  usual  English  measure,  but  the  sections  are  more 
conveniently  described  with  direct  reference  to  the  Austrian  Survey  Map,  by 
using  the  100-metre  contours. 
2  The  name  of  ‘  Heiligkreuz  Schichten  ’  was  first  used  by  Wissmann 
(‘  Beitrage  zur  Geognosie  u.  Petrefactenkunde  des  S.-O.  Tirols/  Heft  iv. 
pp.  19,  21,  Bayreuth,  1841)  to  denote  ‘  einige  graue  Kalksteinschichten, 
welche  auf  dem  rechten  Gehange  des  Abteithals  und  zwar  etwa  in  der  Mitte 
zwischen  der  weithin  sichtbaren  Heiligkreuzkirche  und  St.  Leonhardt  (Abtei) 
ganz  isolirt  zu  Tage  gehen.’  Wissmann  then  gives  the  list  of  fossils.
