The figures which Cuvier has given in his Os semens Fossils, VOL. v. 
tab. 13, figs, 2 and 3, as the Chelonee de Maestricht , precisely agree 
with this specimen; the shield-formed part in the figure represents 
the extent of the testaceous covering of which it is the cast; the shell, 
as before stated, is attached to the other part, and is from one-eighth 
to one-fourth of an inch thick. The fragments seen forming a band 
around it near the edge of the stone, are the remains of the border of 
the Carapace, the intermediate space being (according to Cuvier) 
covered with a cartalaginous substance, which was converted into 
shell as the animal advanced in age. The spine is imbedded in the 
substance of the stone, and along the central line are seen the pro¬ 
cesses of attachment to the Carapace, and on each side of these are 
the broken ends of the ribs, which were sixteen in number. 
Mastodon .—Some doubts have been entertained if Remains of this 
animal existed with us; it appears, however, that the fine Grinder, 
figured in Tab. 1, Smith’s Strata Identified, belonged to that animal; 
it was found in the Crag Stratum at Whitlingham, near Norwich. A 
youug Tooth was found in 1824, at Horstead, in the same county, 
precisely like one brought from Ava, by Capt. Crawfurd, and named 
by Professor Buckland, Mastodon latidens. ( Geol . Trans . vol. n. 
2nd ser. tab. 37, fig. 4). I have a fragment in my collection, which 
I took out of the Crag at Bramerton. 
Elephas . —The finest deposit of these Remains is on the Oyster 
Bank off Hasborough, on the Norfolk Coast; many hundred Grinders 
have been taken up from this locality, and bones without number. 
The Rev. James Layton, of Catfield, has the largest collection from 
this interesting deposit; among which, is a Tusk of the Mammoth, 
(E. primogenius), found on the Knole Sand, on the same coast, in 
1828, which weighs ninety-six pounds, and measures nine feet and a 
half on the outside of the curvature. 
Of the alterations which have been made in the nomenclature of 
Fossils, the following appear to be the most prominent 
Osmunda gigantea of Martin, is Nevropteris flexuosa of Brongniart. 
Pecopteris reticulata of Tilg . Foss. t. 3, f. 5, is Lonchopteris Mantelli of ditto. 
Mantellia nidiformis of Brong. Prod., is Cycadeoidea megalophylla of Buckland . 
Tortoise encrinite of Org . Rem. ii. t. 13, f. 24, is Marsupites Ornatus of Miller, 
and Marsupites Milleri of Mantell. 
Dudley fossil of Parkinson, is Calymena Blumenbachii of Brongniart. 
Teredo antenauta of Sow. Min. Con. t. 102, is Fistulana personata of Sowerbij.
