tioii in the Lahnewiesgraben ; in Austria it had been met with until 

 now only in the next higher formation, — the Upper Lias. 



Avicula insequiradiata, Schafhailtl. Many specimens; this species 

 is found, though rarely, in the strata of Kossen in the Austrian Alps. 



Avicula intermedia, Emmrich ; differing from the very similar forms, 

 Avicula incequivalvis and A. Munsteri, by the number of the ribs. 



Cardium austriacum, Hauer. In some places found in considerable 

 abundance. This is the species designated very often as Cardita 

 crenata. Two lateral teeth in the hinge, v/hich M. Hauer could 

 clearly observe in some of the specimens, place this species in the 

 genus Cardium. The true Cardita crenata of St. Cassian seems to 

 have a very different hinge, although, imtil now, it has not been quite 

 clearly made out. 



Cardium rheeticum, Merian. 



Gervillia inflata, Schafhailtl. In some localities very common, and 

 very characteristic of this formation. 



Lima gigantea, Sow. 



Modiola Schafhautli, Stur .=^M.odiw\di texta, Schafh. 



Nucula complanata, Phill. In some localities very common. 



Ostrea Haidingeriana, Emmrich. 



Pecten Lugdunensis, Mich., according to a determination by 

 M. Merian ; and some other as yet undescribed species of Pecten. 



Pholadomya lagenalis, Schafhailtl. 



Pinna Hartmanni, Zieten. 



Trigonia; similar, according to Von Hauer, to Trigonia harpa, 

 Mvinster, or Trig^ Whateleycs, Buch ; but differing from it, and 

 probably a new species. 



Rhynchonella fissicostata, Suess. 



Terebratula cornigera, Schafhailtl. 



Terebratula gregaria, Suess. 



Terebratula subrimosa, Schafhailtl. 



Spirifer Emmrichi, Suess. 



Spirigera oxycolpos, Emmrich. 



Corals are met with in some parts of this formation, especially in 

 the lower strata, sometimes in great abundance ; the species of these 

 corals, principally Lithodendron and Astrcea, have not yet been de- 

 scribed. 



Only in one locality, on the Katzenstein, some fossils have been 

 found which might seem to indicate a triassic formation ; these 

 were Terehrattda trigonella, Schlotheim, and parts of Crinoidea 

 very similar to those of Dadocrinus gracilis, H. von Meyer ; but 

 with these fossils was associated Natica alpina, Merian, belonging 

 very evidently to the Kossen beds ; nor does the position of these 

 strata give the least evidence of their being different from the Lower 

 Lias in general. 



III. and IV. Upper Lias and Jura. 



A. Upper Lias of Ammergau. — Very well developed and fossilife- 

 rous strata of the Upper Lias occur near Ammergau, immediately in
