ON THE DISCOVERY OF OPHIURA WETHERELLI AT HERNE BAY. 
To the Editor of the GroLtocicaL MAGAZINE. 
Dear Sir,—During a recent visit to Herne Bay I was fortunate 
enough to obtain some specimens of a pretty little Star-fish— Ophiura 
Wetherelli, of Forbes, from what I suppose to be the basement-bed 
of the London clay ; and as this species appears to have been only 
hitherto obtained from the upper beds of the London clay at Hamp- 
stead and Highgate, or in still higher beds at Barton, as mentioned 
by Professor Forbes (Pal. Soc. Mon., page 33), a notice of its oc- 
currence at a lower level in the Tertiary series may possibly be in- 
teresting to some of your readers. 
My specimens of Ophiura were imbedded in a block of hard fer- 
ruginous sandstone in association with numerous specimens of Car- 
dium Laytoni, which formed a layer several inches in thickness, and 
with which indeed they were so closely intermingled as to render 
their extraction, in anything but a fragmentary condition, a matter 
of extreme difficulty. 
The block of sandstone appeared to have fallen from a bed of sand, 
which would answer to group 2 in Mr. Prestwich’s ‘ Section near 
Herne Bay’ (Quar. Jour. Geol. Soc., vol. vi. p. 265), and the place 
on the shore must be about a mile and half east of Herne Bay, and 
about midway between the rise of the sand-beds from beneath the 
London clay and a break or ravine in the cliffs a little further to the 
eastward.— Yours truly, 
C. J. A. MrYEr.

Notes on THE Fossit MAmMats or AUSTRALIA. 
By Gerarp Krert, Esq., Curator of the Australian Museum, Sydney. 
(Extracted from the ‘Australasian,’ August 4, 1865.) 
I believe that the late Sir Thomas Mitchell was the first discoverer 
of fossil remains of mammals in Australia, and they were obtained 
in the caves of Wellington Valley, New South Wales. Some of 
these fossils were deposited in the Australian Museum, at Sydney, 
and others handed over by Sir Thomas to the Geological Society of 
London. 
Professor Owen, who examined them at the explorer’s request, 
states that they belong to the following genera :— 
1. Macropus atlas. O. Larger than the largest known existing 
species. 2. Macropus titan. O. As large as the preceding, but 
differing chiefly in the smaller size of the permanent spurious molar. 
8. Macropus, spec. Not determined by the learned professor, from 
want of skeletons of existing species of kangaroo. 4. Macropus, 
spec. Another undetermined kangaroo. 5. Hypsiprymnus, spec. 
Not determined. 6. Hypsiprymnus, spec. Not determined. 7 and 
8. Phalangista. ‘Two as yet undetermined species. Professor Owen
