PEEFACE.

The want of a Catalogue of British Fossil Crustacea, in which all the
s3-nonyms 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 for other
and more pressing occupations.

Mr. Woodward completed this Catalogue on 22nd December, 1876 ;
and it is but fair to him to state that he could only devote a small
portion of liis official time to this work, having to attend to the
ordinary business connected with the Department, and also to catalogue
the largo accessions to the Fossil Invertebrata.

Some idea may be formed of the progress of palseontological work
in this country from the fact that when Prof. Morris's Catalogue of
British Fossils was published in 1854, he recorded only 81 genera and
30G species of Fossil Crustacea.

The present Catalogue contains a record of 107 genera, and lUol
species and varieties found fossil in Britain ; so that, since 1854, IIG
now genera, and 745 new species and varieties of Fossil Crustacea have
been figured and described in Britain.

INTRODUCTION.

With the exception of one doubtful organism (the Eozoon Canadense) not
met with in the oldest known British Sedimentary rocks, the fossil repre-
sentatives of the class Crustacea take rank in antiquity amongst the earliest
known organic remains.

From the recently discovered P/-e-Cambrian rocks of St. David's, Pem-
brokeshire (the "Dimetian" and "Pebidian" formations) no organic re-
mains of any kind have been obtained ; the Lower Cambrian series, how-
ever, 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 Table at page viii, tiuo
only (printed in Italics) are extinct, namely the Triiobita and the Eurt-
riERiDA, and three are not represented in a fossil state, viz. the Cladocera,
the CoPEi'ODA, and the Khizocepilala.

The small Table below is intended to show at a glance the earliest appear-
ance in time (so far as we have been enabled to ascertain it) of each order,
and its recurrence in each successive formation.

Brachtura. — The oldest known Crab is the PaUeinachus hnylpes, H.
Woodw., from the Forest Marble (Great Oolite), Wilts. The Crabs are
well represented from the Jurassic period to the present day, when they
attain their maximum development within the warm, temperate, and sub-
tropical latitudes, where land, freshwater, and marine species abound.

Anomttra. — The Anomura embrace forms of Decapoda both related
to the Brachyura (e. g. Droviia, Porcellana, Dorip-pe, &c.) and to the Ma-
crura {e.g. Pagiirus, GalatJiea, Munida). Their earliest appearance is in
the Cretaceous period. Numerous species of land and marine Anomura
are found within the tropics ; and the marine species -occur very widely
distributed in the colder seas of the globe.

Maorura. — Of this division of the Decapoda a single species, the An-
thrapalccmon Grossartii, occurs in the Coal-measures, and is well repre-
sented from the Trias to the present day. There are abundant freshwater
and marine, but no ?«jif?- dwelling Macrura.

Stomapoda. — One species (the Pygocephalus Buxleyi, H. Woodw.), from
the Coal-measures, is probably referable to this division. True Si-imllce
and Mysis-Yike Crustaceans occur in the Jurassic rocks. They are most
abundant in our modern seas.

IsoPODA. — The remains of a single species of Isopod, Prceanturics gigns,
H. Woodw., have been obtained from the Old Red Sandstone of Hereford-
shire ; and other representatives occur in the Carboniferous and Secondary
rocks. The Isopoda are most widely distributed over land and sea today :
terrestrial, freshwater, and marine species abound.

Trilobita. — This extinct order ranges from the Lower Cambrian to the
Carboniferous Series, more than 300 British species being described, and in
Bohemia 350 species have been named and figured by Barrande alone.
The great Paradoxides Davidis measures nearly 2 feet in length. As this
group ascends in time, we find the extravagantly ornamented and
spinose forms, such as Paradoxides and Acidasjns, disappear ; and only
three genera survive in the Carboniferous, small in size, and very regular
and neat in form, especially the genus Griffithides.

AMPniPODA. — The order Amphipoda has one representative in the Upper
Silurian (the Necrogatiimarus Saliueyi, H. Woodw.); it is represented by
Gampsonyx in the Coal of Rhenish Prussia, and by the genus Prosopo-
7iiscus in the Permian of Durham. Other (Secondary) species occur in
Bavaria &c. The living genera of Amphipoda are abundant, both marine
and freshwater ; and some species are even terrestrial in their habits.

Xtphosura. — The earliest representative of the King-Crabs known is
the NeoUmidus falcatus, H. Woodw., from the Upper Silurian of Lanark-
shire ; several species are met with in the Coal-measures, and are very
widely distributed. The genus is represented largely in the Oolite of
Bavaria, and is also found living todav in both the Old and New World.

INTROUUCriDN. VI I

EuKYi'TJUiiuA. — The Eukypteuida, like the Thilobita, are an extinct
order. They were represented in Devonian and Silurian times by g;enera
which attained a length of from 5 to 6 feet. They were nearly related to
the King-Crabs in structure, but differed in their development as do the
Lobsters from the Crabs at the present day — the XipnosuRA representing
the Brachyuran, and the EuRrPTERiDA the Macruran tj'pe.

Phyllopoda. — The Phyllopoda arc represented from the Middle Cam-
brian to the Tertiary period by many genera. Large extinct fonns, closely
resembling the little modern Nehalia Inpes, were abundant in the Upper
Silurian of Ludlow and Lanark. They are represented today by species
in fresh water, brackish water, salt water, and highly saline salterns and
lakes.

OsTRACODA. — The Bivalved Entomostraca included in this order are
largely represented throughout the entire scries of stratified rocks, from
the Lower Cambrian to the present day ; they are equally well represented
in a recent state. They not unfrequently (as in the Cjipris shales of the
Wealdcn) make up entire strata with their accumulated valves.

CiRRiPEDiA. (rt) Balanid.!). — The oldest fossil sessile Cirripede is the
Pijr(joina cretacea, H. Woodw., from the Upper Chalk of Norwich.

(6) LEPADiDiE. — The oldest known pedunculated Cirripede is the Turri-
lepas Wnyhtil, H. Woodw., from the Upper Silurian of Dudley. None
have been met with lower than the Lias, except Tun-ilepas ; but from the
Lias upwards, sessile forms are well represented.

The group is abundant and cosmopolitan in aU the seas of the world,
parasitic on all objects, living and dead.

The subjoined Table (p. viii) gives the number of genera, species, and
varieties belonging to each order and suborder in the class Crustacea.
