7. Ueber zwei neue dyadische Pflanzen ; by Dr. H. B, Gurnrrz (Jahrb, 
Sir Min, etc., 1863, pp. 525-530).—Of the two new plants of the Per- 
mian here described by Dr. Geinitz, one is from the Rothliegende of Ot- 
tendorf near Braunau in Bohemia; it is named Schittzia anomala, 
is a stem in fruit; it is regarded by the author as probably Coniferous, 
and near the living Cryptomeria. The other is from the lower Permian 
of Hohenelbe, and is apparently a root, as the name given it, Rhizolithes 
Kablike, implies. The paper is illustrated by two plates. 
8. Beitriige zur Kenntniss der organischen Ueberreste in der Dyas. 
(order permischen Formation zum Theil) und tuber den Namen Dyas ; 
by Dr. H. B. Gernirz. With two plates. (Jahrb. f. Min., 1863, pp. 
865-398.)—Dr. Geinitz here describes and figures the Prosoponiscus 
problematicus (which he refers to the Isopod Crustaceans), Syringopora 
fischeri Gein., Saurichnites Leisnena Gein., Saurian skin from the lower 
Permian of [uttendorf near Hohenelbe, and remarks upon the preten 
identity of fossils of certain British Carboniferous and Permian schis 
and also upon the name Dyas, of Marcou, used by him for the Permian, 
Under this last head, Dr. Geinitz shows that ‘the Dyas has different 
limits from those before given to the Permian, Yet we still think, with 
Murchison, that the accepted name of Permian may without inconven- 
lence and more properly be extended to cover the whole. We see 
_ advantage in a change, and least of all to one based on a mere accident, 
¢ number of subdivisions of the formation in a particular region. ;
