stone, exhibit casts of the interior only as in figs. 1 a and 6. 
LLANDOVERY.—Lhis species is also included in the fossils of the Caradoc for- 
mation with a query; Sil., fourth edition, p. 511. It is said to be more 
frequent in the Upper than the Lower Llandovery. “Lbid., p. 208. Locali-

Nors.—I have followed the authors of British Fossil Corals by includ- 
ing this coral in the genus Cyathophyllum to which it evidently belongs. 
The specimen from which fig. 1 ¢ is taken shows both external and internal 
form ; confirming the opinion of the authors of that work as to the fossils 
Turbinolopsis or Petraia, being merely casts of corals belonging to this 
genus. Brit. Foss. Corals, Silurian Formation, Paleeontographical So-
