II.—Contributions to the Palæontology of the Yorkshire Oolites

Published online by Cambridge University Press:  01 May 2009

Extract

The species belonging to this Order, which are enumerated below and figured in the accompanying Plate, occur in the Lower Oolites without exception. The Oxfordian beds in Yorkshire have not been productive in fossils of this kind: the onlyknown species—Actœon retusus, Phil.—has already been described in the “Corallian Gasteropoda” (Geol. Mag. 1881, p. 127, Pl. IV. Fig. 7). The Tornatellidæ are the best represented, and especially Actœonina, but none are numerous, and really good specimens, suitable for accurate description, are rare indeed.
