Switzerland 

 A single species, Oinhgo Jaccardi, is described by Heer'' from Swiss 

 deposits which are considered of lower Aptian age. 



Italy 

 The so-called scaly clays of Emilia, Italy (argiles ecailleuses, argille 

 scagliose), have been referred to a number of geological horizons, but of 

 late years, as a result of the studies of" Capellini,* they have been con- 

 sidered of Lower Cretaceous age, the cycad trunks for which they are 

 chiefly celebrated being considered Aptian, The following species of the 

 latter have been described : 



Cycadeoidea Bianconiana Massalongo 

 Cycadeoidea Capelliniana Solms. 

 Cycadeoidea cocchiana Caruel
