 seems to be uncertain. Of the two species described by Gros« 

 souvRE from the Cretaceous of France, viz. H. Fayoli^^ and H. 

 Welschi,"^ the former is in the Campanien and the latter in the 

 zone of Mortoniceras texaimin. 



The present writer proposes to bring two other species 

 under this genus. Tlie one is Amm. lagarus Redtenbacher^^ 

 from Gossan which shows such agreement in every particular 

 with the above mentioned typical species that the writer has nO' 

 hesitation in stating their generic identity. The other is a new 

 form found in the Cretaceous of the Hokkaido, and is described 

 below under the name of //. antjiisttim.
