Miscellanies. 197 
“A large portion of another skeleton of a different reptile, which 
Mr. Mantell calls the Hyleosaurus or forest Lizard,: presents some 
remarkable characters,—particularly a row of terrific spines, 17 
inches long which were probably erect on the back, and in this res- 
pect realized the forms of the fabled dragons of romance. 
“« M. Agassiz spent four days chiefly in examining the fossil fishes ; 
and he regretted that his engagements as Professor in a foreign uni- 
versity compelled him to return so soon. During his visit, I had 
several times the pleasure of meeting M. Agassiz and Mr. Mantell 
in the museum, with Dr. Buckland, Dr. Faraday, Mr. Lyell, and 
Mr. Ricardo.—B.” 
10. Specimens from Mr. Mantell.—We have often been indebted 
to the liberality of this distinguished friend and eminently successful 
cultivator of science, for interesting specimens from the truly classical 
geological region in which he resides; among many recently receiv- 
ed are the following. 
Marsupites Milleri: two very fine specimens: the chalk being 
more completely removed with a penknife, the structure will be still 
more evident. 
A cast of the inferior or condyloid extremity of one of the largest 
femurs of the Iguanodon in Mr. Mantell’s Museum: from Tilgate 
forest. Its lower extremity is thirty four inches in circumference ; 
it is like a stick of timber. 
Casts of three claws or unguical bones of reptiles, viz. claw bone 
of the hind foot, claw bone of the fore foot of the Iguanodon; the 
former were hooked or curved, like those of the Iguana, the latter 
compressed like those of the land turtle. Claw bone of a Croc- 
odile. 
A very fine portion of a young Elephant’s tooth, from Brighton 
Clifis—very rare. 
A good series of characteristic shells of the Brognor rocks, (Hamp- 
shire tertiary basin—vide G. S. E. of England,) Western Sussex. 
Fossils from Stonesfield: these in addition to the specimens for- 
merly sent, will form a good suite of the organic remains of these ex- 
traordinary deposits. 
Ribs of Iguanodon. The portions of ribs in sandstone from Til- 
gate Forest will serve to convey an idea of the usual appearance of 
the specimens in Mr. Mantell’s collection that were imbedded in 
sandstone, and are very distinct and perfect.
