the Muschelkalk is}the Encrinus liliiformis (Fig. 361). Species of 
urchins (Cidaris) are common in ‘the Alpine Trias. The more 
frequent brachiopods are species of Terebratula (T. vulgaris), Retzia, 
Spirifera, and Lhynchonella. Of the lamellibranchs one of the 
most distinctively Triassic is Myophoria (M. vulgaris, M. Kefersteint,
