NOTES. 
colour, while the margin is a dark brown; the sulci are eight or ten 
* in number. The last kind are found in the hard Chalk of western 
Norfolk, and are much smaller than the preceding; they are the same 
colour as the first kind, but the sulci are twice as numerous, their 
form is nearly oval.'— Organic Remains , vol. hi. tab. 18, fig. 12. 
Sqnalus . —Teeth and Vertebrae of the Shark occur in the Hard 
Chalk of Sussex, Cambridge, and Norfolk; the Teeth are found in 
the Tilgate Beds, and in all the super strata; those from the Chalk 
are the most interesting to collectors; the London Clay specimens 
next. They are of frequent occurrence in the Essex Crag, as is also 
a triangular Tooth, about an inch long, belonging to a fish of the 
same genus.— Organic Remains , vol. lii. tab. 19, fig. 2. 
Birds .—The bones of Birds described as occurring in the Stones- 
field Slate, are now determined to belong to a species of Pterodac- 
tylus.— Geol Trans . 2nd ser. vol. iii. p. 219. 
Coprolites. —Dr. Buckland, in his researches, has discovered that 
the Bezoar stones of the Dorsetshire coast, and the Juli of the Hard 
Chalk, are petrified faecal substances ; on this subject he has given a 
paper in the Geol . Trans . vol. iii. 2nd ser. p. 223, with numerous 
figures. Dr. B. designates those found with Icthyosauria in the Lias, 
Icthyo-sauro-coprus, (tab. 29); those found with Amia, in the same 
beds, Amia-coprus ; those in the Chalk of Cherry Hinton, Cambridge¬ 
shire, hitherto considered the Juli of the Larch, lulo-eido-coprus, 
(Org. Rem . vol. i. tab. 6 , figs. 15 and 17.); and the faecal matter 
of the Hyaena, from the Kirkdale Cave, Ilyceno-coprus, ( Reliquice 
Diluviana , tab. 10, fig. 6). 
Chelonia Harvicensis . —The Fossil Turtle, a lithograph of which 
I made to place at the head of this work, was presented to The Nor¬ 
folk and Norwich Museum, by the Rev. J. H. Bloom, of Wells, now 
of Eaton Villa, near Norwich. It was dredged up in 1827, on the 
t( Stone Ridge/’ four miles out at sea from Harwich harbour, and is 
considered the finest specimen this country has produced. It was 
imbedded in a cement stone (belonging to the London Clay stratum;, 
of a compressed ovate form, which on breaking up the fossil was 
discovered; the part figured is, as represented, uninjured, but the 
upper part, containing the Carapace, is broken into several fragments. 
It is said to have weighed, when perfect, one hundred and eighty 
pounds, and it measures eighteen inches by twenty-two.
