Summary:
Sends information about Pliocene fauna of the "Forest Bed" of the Norfolk coast.
A genus described as extinct by Owen is found by E. A. I. H. Lartet to exist in Russia.
Edouard Suess attributes to Oswald Heer and HF the generalisation "That the time during which a new species is formed, is (as a rule) very short in comparison with the time during which it persistently presents the same peculiar specific characters". [Edouard Suess, "Über die Verschiedenheit und die Aufeinanderfolge der tertiären Landfaunen in der Niederung von Wien", Sitzungsberichte der Kaiserlichen Akademie der Wissenschaften in Wien (Math-naturw. Klasse) 47 (1863): 306–31.] [See 4277.]
