2nd Fauna ...

Cystidea.

Bavarica, Barr.|Hof (Bavaria ).

N.B.—The majority of the genera and species indicate the primordial fauna, while the four genera of Trilobites, Asa-phus,Lichas, Calymene , and Cheirurus, announce the second fauna, the species being rare. Thus this fauna of Hof seems to con- jstitute a transition and connexion between the first two Silurian faunae.— M. Barrande. I

There are a few more Hof fossils scattered about in the ‘ Thesaurus.’ I
