288 EMMERICH ON THE MORPHOLOGY, CLASSIFICATION 
lesia, on the other hand, possesses another remarkable Trilobite 
locality of Germany, in addition to its northern specimens, in the 
so-called grauwacke of Falkenberg, a member of the carbonife- 
rous formation of the coal system. 
Of the enumerated grauwacke systems of Germany, probably 
none exceeds that of Bohemia in point of age. Between Beraun 
and Pilsen, in a generally darkly coloured grauwacke, we find 
the Oleni (O. Tessini, spinulosus), which hitherto have not been 
found anywhere excepting in Sweden and in North America. 
Conocephalus and Ellipsocephalus are peculiar to this formation. 
It can only be decided at the locality itself whether the more 
yellow rock, in which Phacops proavius (a species most nearly 
related to Ph. Downingie) occurs, belongs to the same grau- 
wacke, or to a younger. Count Sternberg makes mention of a 
lighter grauwacke, which appears to the north of the former, 
and accompanies the coal formation. Older limestones, subor- 
dinate to the grauwacke, and containing fossils, are not known. 
A range of young transition limestones commences on the other 
hand at Prague, and extends from Karlstein to the vicinity of 
Zebrak. It abounds in Trilobites: we know from it Phacops 
macrophthalmus, protuberans, Hausmanni, Trilobites Sternbergii, 
and some small remains which require to be more accurately 
investigated, and from which Zenker formed the genus O¢arion. 
What are not peculiar to Bohemia occur in the Devonian strata 
of England (Ph. macrophthalmus, Calymene Sternbergii). 
I am not acquainted with any Trilobites from the grauwacke 
and clay-slate of the plateau of Voigtland ; the fossils found there 
however do not lead us to expect the discovery of the Bohemian 
Oleni. ‘The limestones of the Fichte] Mountains, on the other 
hand, are richer in fossils in the vicinity of Hof. Among the 
numerous fossils which Count Miinster discovered in them are 
also Trilobites: species of Brontes, Calymene Sternbergii, dif- 
ferent species of Phacops, with a large trapezoidal lobe of the 
forehead, and with an evanescent small lobe of the forehead 
(Ph. granulata, intermedia, levis, Minster, Latreillii, Stein.). 
The Bumasti and Iliene have been found in too imperfect a 
condition to deserve any consideration. All the Trilobites that 
admit of being determined correspond with those of Branik and 
Karlstein, as well as with those of Devonshire. 
The Trilobites of the Hartz are known from Reemer’s work 
on the Fossils of the Hartz (Hanover, 1843). He represented
