342 M. Ogilvie Gordon — Fauna of Upper Cassian, South Tyrol. 



the Echinoderms, Pentacrinus Tirolensis and Cidaris parastadifera, 

 continue in the highest Eaibl horizons. In all groups the revised 

 list is found to fulfil the requirements of a palseontological bridge 

 between the Stuores-Cassiau and the Schlern Plateau (or Upper 

 Cardita) strata, and therefore to merit the place I assigned to the 

 fauna in the percentage table and accompanying remarks of my 

 earlier paper (Q.J.G.S., 1893, p. 44 ; also Geol. Mag., 1894, p. 10 seq.). 

 I now submit the complete series of Upper Triassic zones in 

 Falzarego Valley.
