THE GEOLOGIST. 
the quarry in which the remains of the Iguanodon were disco- 
covered in 1834^ where it was associated with Fucus Targionii, 
and some indeterminate species of the same genus ; stems and 
apparently traces of the foliage of endogenous trees allied to the 
EraccBua {Sternhergia) , and of trunks and branches of Conifer cs. 
The wood occurs both in a calcareous and silicious state. The 
cone found is in every respect such a fruit as the trees, to which 
the wood belonged, might have borne. It bears a close resem- 
blance to a fossil from the greensand of Dorsetshire, discovered 
by Dr. Buckland, and figured in the ^ Fossil Flora^ of Great 
Britain under the name of Ahies ohlonga (Fos. Fl. pi. 1.). Un- 
fortunately the outer surface is so much worn that the external 
figure of the scales cannot be accurately defined ; but the sec- 
tions show their proportionate thickness. There is an opening 
at the base of the cone occasioned by the removal of the stalk, 
and an accidental oblique fracture exhibits the internal structure. 
In the longitudinal section thus exposed the scales are seen to 
be rounded and broad at their base and to rise gradually, and 
become thin at their outer terminations. The seeds are oblong, 
and one seed is seen imbedded within the base of each scale. 
Mr. Morris considers it to have a great affinity to Ahies ohlonga 
of Lindley and Hutton, but it is more spherical, and the scales 
are smaller, more regular, and numerous. 
3. Carpolithes Smithies, Mantell. — From the white chalk of 
Kent. An account of an imperfect specimen of this fruit was 
formerly given by Dr. Mantell in his * Illustrations of the Geo- 
logy of Sussex.^ He lately detected a second and more perfect 
example in the choice collection of Mrs. Smith of Tunbridge 
Wells, in honour of whom he has named it. Dr. Mantell re- 
marks, that a slight inspection was sufficient to determine its 
vegetable origin, for several seeds were imbedded in its substance, 
and others had been detached in clearing it- from the chalk. Dr. 
Robert Brown suggested that the original was probably a succu- 
lent compound berry, the seeds appearing to have been imbed-
