Dorset ; the series of Lily Encrinites (Apiocrinus Farkinsoni), from 
Bradford ; and of Marsupites Milleri, from Kent and Sussex. 
In this Case is also placed the unique example of the Solaster 
Moretonis, sl large many-rayed Star-fish from the Oolite of Gloucester- 
shire, presented by Earl Ducie. 
Sea-urchins (Echinidce). Case 22, Room VI. These are arranged 
in four principal groups. 1. Those from the Tertiary strata, of which 
the most remarkable are the large Clypeasters from Malta. 2. The 
Chalk Echinidcc, amongst which are the Helmet-urchins (A?ianchytes), 
popularly known as "fairy-loaves;" the Heart-urchins (Spatangida), 
called " fairy -hearts;" and numerous species of Cidaris, provincially 
termed "shepherd's crowns;" some of the specimens have spines 
still attached to the shell. 3. The Jurassic or Oolitic Echinida, and 
the Sea-urchins from the Trias and older rocks, which include many 
singular forms of the spines or locomotive organs. 
Worms (Annelida). One half of Case 18, Room V., is occupied 
with examples of the tubes, or shells, of fossil Annelids (Serpulce). 
One species, known as the Vermicularia Bognoriensis, makes an almost 
regularly convoluted tube, like a snail-shell ; a mass composed of these 
tubes is placed in this Case, and another upon the Window-sill ad- 
joining. 
Fossil Insects (Articulata). The other half of Table Case No. 18, 
Room V., contains the Insect remains, consisting of the wing-covers 
(elytra) of beetles from the Oolitic strata of Purbeck and Stonesfield, 
and Dragon-flies (some in their larval state), from Solenhofen and 
CEningen. There is also the wing of a large Hying insect, resembling 
the living Corydalis of the United States, in a nodule of clay-ironstone 
from Coalbrook Dale. 
Fossil insects may be seen in some of the specimens of amber in 
the Table Case No. 60, Room I. 
Crustacea,— Crabs and Lobsters. Cases 7 and 9, Room VI., 
contain the exhibited portion of this class. The first half of Case 9 
contains the Cirripedia, represented at the present day by the Ship 
Barnacle and the Acorn-shell. The second contains the Bivalved 
Crustacea, Phyllopods and Ostracods ; and the Eurypteridce saidLimu- 
lidce, or King-Crabs. The gigantic Eurypteridce are extinct, but the 
King-Crab is found living at the present day. A fine example of 
Limulus, from Solenhofen, and of Slimonia, from Lanarkshire, are 
placed in this case. Other examples occupy the Window. 
Case 7 contains the Trilobita, the Isopoda, and the Decapoda (Crabs 
and Lobsters). Of the Trilobites, by far the greater part are from the 
Wenlock Shale and Limestone of Worcestershire and Staffordshire, and 
the Silurian rocks of Bohemia. The " Dudley Locusts " (Calymene Blu- 
menbachii) and the great " Barr Trilobite " (Ilhenus Barriensis) are 
among the earliest fossils known to science. Fossil Lobsters are 
found to extend from the Coal Measures to the present day ; whilst 
true Crabs first appear in the Upper Oolite. Specimens from the 
Lias of Lyme, the Oolite of Solenhofen, and the London Clay of 
Shenpew are most ^esorvinrr of attention.
