Notices of Memoirs — Prof. Owen — 
I conclude wdth appending a table in wliicli tbe various local beds 
are correlated as far as possible with one anotber. I would point 
out that the horizon of the Malm-rock is somewhat uncertain, but 
tbat its fauna appears to belong to that of the P. asper zone ; also 
that I have included Etage B, and beds 5 and 6 of the Devon section, 
in the same division, thus giving to it a thickness of from 35 to 
45 feet. 
While thus endeavouring to limit satisfactorily the three stages 
into which the Gault and Greensand can be divided, and which it 
is important to recognize, it must be remembered tbat they really 
pass into one anotber and form a continuous series; so that it is 
impossible to draw very definite lines betvveen them such as that 
which does exist above the P. asper zone and divides it froin the 
overlying Chalk-marl.

I. — Professor Owen’s Fossil Mammals of Australia. 
I N pursuance of bis aim to leave records of the vertebrate fossils of 
our Colonies, Prof. Owen, after the issue of bis “ Catalogue of the 
Fossil Reptilia of South Africa ” (4to. 1876), proceeded to prepare 
for press his'notes “ On the Fossil Mammals of Australia,” portions 
of which have from time to time appeared in the “ Philosophical 
Transactions.” To the materiale systematically arranged in the 
work now issued he has premised a chapteron the Fossil Marsupials 
of Great Britain, the wliole being included in two quarto volumes. 
one of text (pp. 522, with interspersed woodcuts) ; the other of 
plates, 132 in nurnber, under the title “ Researches on the Fossil 
Remains of the Extinct Mammals of Australia.” The aim of this 
work is, mainly, to afford the Australian students of Palajontology a 
ready means of comparison of the mammalian fossils which may
