Abstract
ONLY a Palæontologist who has lived through much of the development of his science could produce volume such as this. The brachiopod and molluscan fauna of the Productus Limestone is describes in detail with a wealth of references. Though only two new genera, Blandfordina (Limidæ) and Palæolecanites (Lecanitidse), and one new subgenus, Haydenella (Productus), are found necessary, there are no fewer than 177 new species and 114 new varieties. In this revision of the fauna certain of the conclusions reached by Waagen in an earlier monograph are rejected. In particular, the supposed Visean affinities of a number of species from the Lower Productus Limestone, and the proposed palæontological zoning of the Middle and Upper Productus Limestone, are shown to be unsupported by evidence. The present author considers the Productus Limestone to be wholly Permian in age.
