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 JZyuanodon 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!:— 
Lonchopteris Mantelli, Brong. = Weich- ; Sphenopteris Gépperti, Dunk. =Ruf- 
selia Mantelli (Brong.). Sordia Gépperti (Dunk.). 
Pecopteris polymorpha, Dunk. =Clado- | §. Roemeri, Dunk. = Onychiopsis Man- 
phlebis Dunkeri (Schimp.). telli (Brong.). 
P. Conybeari, Dunk. = Matonidium | Gleichenia? 
Gopperti (Ett.). Gleichenites. 
Alethopteris elegans, G6pp. =I. Gép- 
perti (Ett.). 
We have the late Prof. Newberry’s testimony’ that no trace 
of any Angiospermous species occurs among the plants found with 
the Jguanodon 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.® 
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. 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.’ The
