On some Reptilian Remains from North-western Bengal. 587. 
_At Mangali, between 50.and 60 miles S.. of Nagpur, dark red 
sandstones are found, rich in Estheria, and containing remains of 
Plants, Ganoid Fishes, and Reptiles (Brachyops laticeps, Owen). 
These beds Mr. Hislop thinks to be of the same age as those of Nag- 
pur and Chanda. Still further 8. (170 miles from 1 Nagpur), at Kota, 
there are (under thick sandstones) limestones and shales, containing 
fishes of the genera <Zchmodus and Lepidotus, Teleosaurian remains 
Coprolites, fossil Insects, Cypride, and Estherie, with obscure plant- 
remains. These beds are also regarded by the author as equi- 
valent in age to the plant-bearing sandstones of Nagpur ; whilst the 
‘sandstone above them may be equal to the sandstone of the Maha- 
dewas ; and the red clay beneath them may be the same as that of 
Maledi 30 miles off (to the N.E.), where Ceratodus teeth and Co- 
prolites have been found in abundance. 
Mr. Hislop then compared in detail, 1. the fossil flora of the coal- 
fields of New South Wales with that of Central India; 2. the fossil 
plants of Western Bengal with those of Central India ; and 3. the 
fossil fauna of these two regions ; and came to the conclusion that, 
on the whole, they probably represent the Jurassic (or possibly the 
Triassic) period,—at all events some portion of the Lower Mesozoic 
epoch. 
3. “On the Geological Age of the Coal-bearing Rocks of New 
South Wales.” By the Rev. W. B. Clarke, F.G.S. 
_ The author first referred to his report, in 1847, of the occurrence of 
Lepidodendron, Sigillaria, and Stigmaria in the coal-fields of Australia ; 
and advanced proofs of the occurrence of Lepidodendron (Pachy- 
phleus (?), Goeppert) over a region extending from 23° to 37° S. 
lat., and at least 1000 miles long. After some observations on the 
association of Carboniferous and Devonian fossils with the coal-beds - 
of Australia and ‘Tasmania, Mr. Clarke stated that in 1859, at Stony 
Creek, near Maitland, Mr. B. Russell, having sunk two pits in search 
ef coal, found four or five coal-seams lying between beds containing 
Pachydomi, Spiriferi, Orthoceratites, Conularie, &c.; and beneath 
them a shale containing Neggerathia, Glossopteris, Cyclopteris, &c. 
From this and other evidence the author is induced to believe that 
the beds are of paleozoic age, in spite of the “ Jurassic ” appearance 
of the plant-remains. 
4. “On some Reptilian Remains from North-western Bengal.” 
By Prof. T. H. Huxley, F.R.S., Sec.G.S. 
Some bones, found by Mr. Blanford in the uppermost portion of 
the ‘‘ Lower Damuda” group of strata in the Ranigunj coal-field, 
and forwarded to the author by Professor Oldham, have proved to be- 
long to Labyrinthodont Amphibia and Dicyncdont Reptiles, hereby 
affording new and interesting links with the fossil fauna of the 
Karoo-beds of South Africa, and largely increasing the probability 
that the rocks in which they were found are of Triassic, or perhaps 
Permian, age.
