Abstract
THIS publication, we are told, is concerned with the illustration of ammonites from the Jurassic strata of the British Isles. The present volume includes plates 269-422, good, bad, and indifferent, but in numbers a generous proportion of the whole. In a work entitled “Type Ammonites “the illustration of old and hitherto unfigured species is appropriate; but the publication of Chalcedoniceras chalcedonicum, for example, has yet to be justified, generically and specifically; and in the absence of descriptions, Galilæiceras, Galilætes, Galilæanus, and others, possibly from the same bed, may well be taken to be individual variations of one species.
Type Ammonites.
By S. S. Buckman. Vol. 4. (Reed, in 11 parts.) Pp. 68 + 197 plates. (London: Wheldon and Wesley, Ltd., 1922–3.) 6l.
