244 General Notes. 
Diceras-chalk of Kelheimer, in the 32d volume of Palwontographica. 
Four plates illustrate the memoir. 
CaRBONIFEROUS.—Mr. Kliver describes (Palewontographica, 
Band. 32) various arthropod remains discovered in carboniferous 
strata of Saarbrucken and Wettin-Libejiiner. The species include 
an Ectoblattina, two species of Termes, a Dictyoneura, and an 
Acridites, 
Prof. Boyd Dawkins states his conviction that the sound- 
ings for the proposed tunnel across the Straits of Dover will 
bring to light the existence of vast beds of coal, connected, on 
the one hand, with the coal measures of Belgium and the north 
of France, and, on the other, with those of Wales and Somerset- 
shire (England). 
PERMIAN.—The second part of Dr. Anton Fritsch’s “ Fauna 
der Gaskohle and der Kalksteine der Perm-formation” of Bohemia, 
has been published. These strata rest upon Silurian rocks. The 
coals, clays, and ironstones have a carboniferous facies, and the con- 
formable limestones are believed to be true Permian. “ The palæon- 
tological evidence,” says the reviewer in Nature, “is somewhat 
anomalous in the views of purely British fossilists, but it s 
very forcibly and in a most suggestive manner to the students of 
the Gondwana formation of Hindustan.” ‘Two new species O 
Dendrerpeton are described, and a family Dendrerpetonide 18 
characterized. 
M. Bayle has found two entire specimens of Gaudry’s 
Actinodon frossardi in the Permian deposits at Telots. Gau- 
dry’s descriptions were based upon fragments discovered near 
Antun. Actinodon was probably a carnivorons reptile about 25 
feet long, living more upon land than in the water, and formed for 
gliding serpentine movements. The stage of evolution presen 
by this reptile is comparable, according to M. Gaudry, to that of 
the Chelydosaurus of Bohemia, the Zygosaurus of Saxony an 
Russia, the Platyops of Russia, the Gondwanosaurus of Hin ustaD, 
and the Trimerorhachis and Eryops of Texas. Its scales were 
disposed in chevrons, its vertebre were formed of separated pieces, 
and its large ribs gave attachment to ample muscles. 
The internal shell of the Sepiadæ, and its relations 
the Belemnites, forms the subject of an article by Dr. ™ 
Riefstahl in Volume 32 of the Paleontographica. 
The fossil flora of the Red Sandstone and Muschelkalk of the
