THE GEOLOGIST, 
The inferior oolite is the only member of the Jurassic series 
which is well developed, and contains granular ironstone, more 
especially abounding at Meitesheim and Gundershofen — -greatly 
resembling that found at Kandern in Baden. 
6. Comparison of the lias of Metz with that of Niederhronrij hy 
M. Simon. — Masses of ironstone are abundant in the lias of 
this district, not sufficiently rich however for working ; neither 
Gervillia nor Trigonia are found, but are met with in the calcaire 
* a Pecten lens, an inferior member of the oolitic group. 
The bed, inclosing so great a number of fish teeth, and situ- 
ated, according to M. Engelhart, in the upper portion of the 
Keuper, is also found in the department of the Moselle, and 
may be observed better than in ordinary near Pange and Hom- 
bourg, on the right bank of the Moselle, between Metz and 
Thionville. 
7. On the Saurians of the Muschelkalk of Lorraine and Alsace, 
hy M. MouGEOT. — Having directed especial attention to the 
study of Saurian remains, M. Herman de Meyer, by the aid of 
numerous materials furnished by M. Mougeot and the Museum 
of Natural History at Strasburg, has been enabled to establish 
the identity of several species, the existence of which in the 
Muschelkalk of the neighbourhood was unknown ; and, by these 
means, has established a perfect identity between the Muschel- 
kalk of the Vosges and other countries. The fii-st of these re- 
mains is the Simosaurus, a new and well established genus, 
founded on a critical examination of a great number of teeth 
and fragments of the head, and nearly approaches the Notho- 
saurus; — the species found in this neighbourhood has been 
named S. Guillardoti, Besides this, he has discovered Notho- 
saurus Andriani and Muensteri, species which had only been met 
with in Frankonia heretofore ; added to these, is a third entii-ely 
new species, named N. Mougeottii, and fragments of N. mira- 
hilis. M. de Meyer has been fortunate enough to distinguish 
some traces of affinity to the Labyrinthodontes in a new species
