Reviews — Catalogue of British Fossil Crustacea. 413 
Peel, wliich 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 oe British Fossil Crustacea, with their 
Synonyms and the Range in Time of Each Genus and 
Order. By Henry Woodward, F.R.S., F.G.S., of the Depart- 
ment of Geology, British Museum. 8vo. pp. 168. (London : 
Printed by order of the Trustees, April, 1877.) 
T HE want of a Catalogue of British Fossil Crustacea, in wliich all 
the synonyms should be given, has long been feit. The 
present task was commenced some years since; but, owing to the 
unsatisfactory state of one group, the Bivalved Entomostraca, whick 
greatly needed revision, the work was for some time laid aside by 
its autlior for other and more pressing occupations. 
Thanks to the labours of Messrs. Brady, Crosskey, and Robertson, 
wkose Monograph on the British Fossil Post-Tertiary Entomostraca 
forrns quite a volume of itself in the Monographs of the Palaeon- 
tographical Society for 1874, this portion of the work has now been 
very carefully worked out, and when combined with the long 
labours of Prof. T. Rupert Jones, F.R.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 palieontological 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 dass 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 “ Diinetian ” 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 Rhizocephala. 
The small Table is intended to show at a glance the earliest
