7. Filicites curvatus. 
With rhombiform areolae, longly attenuated at either end, the 
lateral angles rounded, marked at the middle with a row of sub- 
ovate cicatrices emitting a line upwards and downwards ; the

Palmacites sqnamosus- Schloth. 395. n. 6. pi. 15. f. 5- 
From the coal mines of Eschweiller and St Imbert. 
9. Filicites trilohatus* 
With rhombiform areolse, the lateral angles rounded, a tri- 
lobate mark of cicatrices in the middle ; the interstices reticulate 
and rhombiform. 
Figured by Nau in Den Denkschriften d- k. Acad- zu Mun- 
chen. 1820. pi. 2. 
I have seen specimens of this, th6 stems of which were up- 
wards of two feet in diameter. 
10. Filicites punctatus* 
With ovate acute areolae, marked toward the base with a cica- 
trix having the form of a horse’s shoe, and at the upper margin 
with a row of dots ; the interstices broadish, reticulato-confluent. 
Lepidodendron punctatum- Sternb. p. 19 pi* 4. 
This is the most distinct ©f all the species, both in regard to 
the size of the cicatrices and tlie rudiments of the fasciculi of 
spiral vessels. Sternberg says that he found the stem hollow, 
which, as it occurs in the adult stems of ferns, shows that the 
structure of this does not differ from tliat of living ferns. 
Found at the river Moldaw, in the county of Kaunitz, in 
Bohemia. 
To what species Schlotheim’s Palmacites verrucosus may be- 
long (see pi. J5. f- 4.), the impression of which is not very well 
^expressed, I cannot venture to determine*
