relics of a reptile, the Stereosternum of Cope. The material 
consisted of some fragments of a stem, which showed numerous 
scars from leaves in dense spirals. A transverse section was 
also obtained of the stem itself; but no organs of fructification 
were to be found. 
The author compares the shape and the arrangement of the 
leaf scars of this plant with those of others from the same forma- 
tion, such as Praronius, Lepidodendron, Lepidophloios and various 
representatives of the Sigillariaceze, and finds a certain accordance 
to those of the Lycopodiaceze. A similar study has been made 
of the anatomical structure of the stem, which in several 
respects does not correspond to that of a Lycopodium. ‘This is 
for instance well marked by the presence of a distinct pith in the 
Brazilian plant, besides that the mestome-bundles are moved 
towards the periphery. It might also be objected for the identi- 
fication of our plant as belonging to the Lycopodiacez, that there 
is a considerable cork developed. But we might, on the other 
hand, take into consideration, that during the carboniferous 
period the trees showed constantly a heavy layer of this tissue 
on account of their exposure to frequent changes of dry or moist 
atmospheres. 
Two species of Lycopodium are known from the same forma- 
tion namely L. punctatum B. R. and L. Renaulti Brongt., but the 
author has preferred, as stated above, to consider this plant as 
representing a new genus Lycopodiopsis, species Derby? B. R. 
H. ENGELHARDT: Cretaceous plants from Bohemia.* 
The comprehensive studies of Velenovsky upon the cretaceous 
flora of Bohemia have already called attention to the numer- 
ous interesting types, that occur in this flora. It was, espe- 
cially, these previous works, that induced the author of the present 
paper to study a collection of plants from the same formation in 
Bohemia, which had not been examined by Velenovsky. Several 
species are enumerated in this note and the author gives a very 
complete synonomy of each species with references to the litera-
