70 LIAS OF ENGLAND AND WALES: 
Concerning the Saurians for which Lyme Regis is noted, most 
of the remains have been found in the Blue Lias series of the 
We?t Cliff' and of the Church Cliffs, and in the overlying dark 
shales and cement-stones of Black Ven. The species are thus for 
the most part preserved at higher horizons than is the case with 
the noted locality of Street in Somersetshire. Remains of Ich- 
thyosaurus (see Figs. 2, 4, and 6, pp. 37-39) from the Blue Lias, 
are found generally in layers between the stone-beds, and a fine 
specimen of Plesiosaurus was obtained from these beds (zone of 
Am. BucJdandi) by Mr. Day.* 
Although for at least 100 years the fossils of Lyme Regis and 
its neighbourhood have been collected for sale, it was not until 
1811 that Mary Anning, the most, noted of the early fossil- 
collectors, obtained the first specimen of Icjitftyosaurus which was 
brought into scientific notice. This was originally described by 
Sir Everard Home, and in 1819 he gave the name Protco-saurus ; 
but in the previous year Koenig had applied the name Ichthyo- 
saurus, and that name, largely owing to the labours of Conybeare, 
became known and adopted. 
In 1821 the same collector obtained remains of another Saurian, 
described by Conybeare under the name Plcsiosaurus (see Figs. 3 
and 7, pp. 37,39); nnd in 1828 she procured (tor the first time in 
this country) the Pterodactyl, of which the species described by 
Buckland is now known as Dimorphodon macronyx. 
Another noteworthy form is the Scclidosaurus Harrisoni, a 
Dinosaur obtained from Charmouth by James Harrison. This 
like many of the other fine Saurians, was obtained piece-meal 
and at intervals. 
Many species of Fishes have been obtained from the Lower 
Lias of Lyme Regis, and to a large extent through the personal 
exertions of the Earl of Enniskillen and Sir Philip Egerton. Little 
however, is known of the special horizons of these fossils, although 
many, such as ^chmodus, Chondrostcus, Dapcditts, Lcpidotus. 
and PacJtycormus are assigned to the zone of Ammonites obtusus. 
Other genera such as Acrodus, Hybodus, and Pholidophorus , 
together with Dapedius have been obtained from the stone-beds 
below.f (See Figs. 8-11, pp. 40, 41.) 
The Coprolites originally described by Buckland were found in 
the same set of beds. (See Fig. 2, p. 37.) There are few 
records of any vertebrate remains from the Belemnite Beds and 
higher stages of the Lower Lias of Dorsetshire. 
Among Crustacea there are species of Eryon, JEyer, Glyphea, 
and Scapheiifi. No Insects are known from the locality. Of 
Echinoderms, certain forms have been noticed in the lowest beds, 
while portions of Pcntacrinus are found more or less plentifully 
at various horizons. The most striking form is the " Briarean 
Encrinite" Extracrinus briareus (Fig. 40, p. 51), which being
