This fauna has ten species in common with the Daoneila shales and 
three only with the Upper Muschelkalk. All of them—Ptychites Gerardi, 
Joannites cf. proavus, Proarcestes Balfouri —range from the Upper 
Muschelkalk into the Daoneila shales. The topmost bed of the 
Muschelkalk group must, consequently, be included in the ladinic stage. 
All the sections in Spiti examined by H. Hayden and A. v. Krafft, 
prove that there is a gradual passage both lithologically and faunistic- 
ally from the Upper Muschelkalk into the ladinic stage. The typical 
fauna of the latter stage is concentrated in the Daoneila shales near the 
base of which the following species have been found : —
