﻿Reviews — Catalogue of British Fossil Crustacea, 413 



Peel, whicli I have not seen, and my arguments only apply to the 

 beds in the south of the island. Having shown that the red beds 

 are not Devonian, I hope in another communication to show what 

 they really are.

I. — A Catalogue of British Fossil Crustacea, with their 

 Synonyms and the Eange in Time of Each Genus and 

 Order. By Henry Woodward, F.E.S., F.G.S., of the Depart- 

 ment of Geology, British Museum. 8vo. pp. 168. (London : 

 Printed by order of the Trustees, April, 1877.) 



THE want of a Catalogue of British Fossil Crustacea, in which all 

 the synonyms should be given, has long been felt. The 

 present task was commenced some years since; but, owing to the 

 unsatisfactory state of one group, the Bivalved Entomostraca, which 

 greatly needed revision, the work was for some time laid aside by 

 its author for other and more pressing occupations. 



Thanks to the labours of Messrs. Brady, Crosskey, and Eobertson, 

 whose Monograph on the British Fossil Post-Tertiary Entomostraca 

 forms quite a volume of itself in the Monographs of the Palceon- 

 tographical Society for 1874, this portion of the work has now been 

 very carefully worked out, and when combined with the lono- 

 labours of Prof. T. Eupert Jones, F.E.S., amongst the older forms, 

 leaves little more to be desired in the completion of this group. 



Some idea may be formed of the progress of palaeontological work 

 in this country from the fact that when Prof. Morris's Catalogue of 

 British Fossils was published in 1854, he recorded 81 genera and 

 306 species of Fossil Crustacea only. 



The present Catalogue contains a record of 197 genera, and 1051 

 species and varieties found fossil in Britain ; so that, since 1854, 116 

 new genera, and 745 new species and varieties of Fossil Crustacea 

 have been figured and described in Britain. 



With the exception of one doubtful organism (the Eozoon Cana- 

 dense) not met with in the oldest known British Sedimentary rocks, 

 the fossil representatives of the class Crustacea take rank in an- 

 tiquity amongst the earliest known organic remains. 



From the recently discovered Pre-Cambrian rocks of St. David's, 

 Pembrokeshire (the " Dimetian " and " Pebidian " formations), no 

 organic remains of any kind have been obtained ; the Lower Cam- 

 brian series, however, have yielded to the labours of Mr. Henry 

 Hicks, F.G.S., and others, remains of Molluscoida, Annelida, and 

 Crustacea. 



Of the thirteen Orders enumerated in the subjoined Table (p. 

 416), two only (printed in Italics) are extinct, namely the Trilobita 

 and Eurypterida, and three are not represented in a fossil state, 

 viz. the Cladocera, the Copepoda, and the Ehizocephala.
