This list is founded upon that given by M. Braun of the fossil 

 plants of the lias of the environs of Bayreuth (Miinster, Beytr. 

 zurPetrefact. fasc. vi. p. 11)^ only the species already named and 

 described or figured being inserted ; and to these are added : 1 . 

 those of the lias of Halberstadt and of Quedlinburg, described by 

 Professor Germar, and those of the lias of Wurtemburg, by Pro- 

 fessor Kurr ; 2. those of the sand of the lias of Hoer in Scania; 

 3. those of certain parts of France, such as Hettange near Metz, 

 La Marche (Haute-Marne), Pouilly (department of the Yonue) ; 

 and 4. certain species of the lias of Lyme-Regis and Whitby in 

 England.

 neighbourhood of Scarborough and Whitby, which M. Unger has
