world, and doubted whether, if these fossils were examined from the 
purely Australian point of view, the same age would be assigned to 
them. 
Mr. Seetzy agreed with Mr. Dawkins, and argued, from the exist- 
ence of natural groups in different areas of the globe, and from the 
succession of life in time, that in no distant locality could the age of 
arock be known from the resemblance of the fossils to an English 
type. 
Mr. R. Tate remarked that if Mr. Moore had compared the Ju- 
rassic fauna with those of India, Africa, and Chili, he would have 
found the same mixture of forms belonging apparently to different 
horizons. He considered that the Australian fossils probably repre- 
sented our Middle Oolite. He did not quite agree with the author 
as to some of the specific determinations. 
Dr. Duncan remarked that the same combination of forms sepa- 
rated in Europe was found among the Tertiary fossils of Australia. 
He thought that further facts were necessary before forming a decided 
opinion as to the succession of the beds in that continent. 
The Presipenr remarked that when we talked of identity of 
fauna in Australia and this country, improbable as it might appear, 
we must remember that at the present time identical species and, to 
a great extent, a similar fauna were to be found in our seas more 
than 180° apart. 
Mr. Moors, in reply, argued that it was the safest plan to follow 
the well-established standard of Europe even in remote parts of the 
world. He was inclined to refer the bulk of the specimens rather to 
the Lower than to the Middle Oolite, but otherwise he agreed in the 
main with Mr. Tate. 
3. On HypsttopHovon Foxit, a new Drnosaurian from the WEALDEN 
of the Iste of Wient. By T. H. Huxiey, LL.D., F.R.S., Presi- 
dent of the Society. 
(Puatzs I. & IT.) 
Dvrine the meeting of the British Association at Norwich in 1868, 
Mr. F. Fellows, on behalf of the Rev. W. Fox, read a paper on, 
and exhibited the skull of, a fossil reptile discovered by that inde- 
fatigable explorer of the rocks of the Isle of Wight in a bed of the 
Wealden formation, ‘‘ which forms the floor of Cowleaze Chine, and 
rises to the top of the sea cliff at Barne’s High, in the parish of 
Brixton.” Mr. Fox considered the reptile to be a “young Jqgua- 
nodon,” or more probably a “‘new small species of Jguanodon,” 
and stated that he had found “several other skeletons” of the 
animal in the same locality. 
In accordance with a wish expressed to me by Mr. Fellows, I 
made as careful an examination of the specimen as the circum- 
stances would permit, and embodied the results of the investigation 
in some observations, accompanied by extemporaneous illustrations, 
which I made before Section C when the paper was read.
