With these species from St. Vaast there should be mentioned 

 the following, which were discovered in the Colliery of Bernissart, 

 in the same beds which have yielded Iguanodon remains in such 

 extraordinary abundance. The species included in the list are 

 given by Dupont in a paper published in 1878, Saporta being 

 responsible for the names 1 : 



Lonchopteris Mantelli, Brong. = Weich- 



selia Mantelli (Brong.). 

 Pecopteris polymorpha, Dunk. = Clado- 



phlebis Dunkeri (Schimp.). 

 P. Conybeari, Dunk. = Malonidium 



Gopperti (Ett.). 



Sphenopteris Gopperti, Dunk. =2t uf- 

 fordia Gopperti (Dunk.). 



S. Hoemeri, Dunk. = Onychiopsis Man- 

 telli (Brong.). 



Gleichenia ? 



Gleichenites. 



Alethopteris elegans, Gopp. = M. Gop 

 perti (Ett.). 



"We have the late Prof, dewberry's testimony 2 that no trace 

 of any Angiospermous species occurs among the plants found with 

 the Iguanodon remains at Bernissart. 



Dr. Bommer, of Brussels, is at present engaged upon the 

 examination of certain Wealden plants recently collected in 

 the neighbourhood of the same locality from which Coeman's 

 specimens were obtained. 3 



RUSSIA. 



In the Bull. Soc. nat. Moscou for 1844, Auerbach figures and 

 gives brief descriptions of some fossil plants from Sandstone 

 strata in the province of Moscow. 4 There is, however, no dis- 

 cussion in his paper as to the age of the rocks, but among the 

 figures a species is represented which has a striking resemblance 

 to Weichselia (Lonchopteris] Mantelli (Brong.). Turning to Mur- 

 chison's " Geology of Russia" (1845), we find the statement 

 that no "Wealden rocks occur either in Russia or Poland. 5 The
