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

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

 zur Petrefact. 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 Iloer in Scania ; 

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

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

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

 England.

 neighbourhood of Scarborough and Whitby, which M. linger has
