The notable facts brought out b) tlii- table are the following. The abundance 

 and concentration of Bchlotheimian forms in the Angulatua zone, and their early 

 appearance in the Rhaatic. The completeness of 1 1 1 * - Caloceran Beries in the 

 lower horizons, and the poverty of the faunas existing between the Geometric us 

 or Upper Bucklandi beds and the Raricostatus bed in respect to these Beries, and 

 ;iK<> in the vermiceran, arnioceran, and coroniceran Beriea The asteroceran 

 reached a liL r li - development as regards the number of forms, but is not 



represented by the extreme modifications noticeable in the l>;i-in <>t' the Rhone.
