Carboniferous Glaciation , Etc .— White. 315 
the palaeontological data, especially the low origin of the 
mesozoic flora, I give the correlation chart published in his 
last paper, 1 with which, however, I have combined the column 
for Africa, along with other materials taken from the two pre¬ 
ceding papers, in the same volume, with palaeontological 
data compiled from all. The range of the genera, Glossopteris, 
Gangamopteris , Vertebraria , and Phyllotheca , is both inter¬ 
esting and important. 
The contemporaneity of the Talchirs, Eccas and Baccus 
Marsh terranes with the marine formations of New South 
Wales was first demonstrated by R. D. Oldham 2 during his ex¬ 
plorations and researches in the latter province in 1886. 
Still another link in the evidence as to the age of the glacial 
formations of India has during the last two years been dis¬ 
covered and confirmed in the “ Olive group ” of the Salt 
Range of the Punjab.. This was the discovery at Nilawan, 
and many other localities in the eastern portion of the Salt 
Range, of incontestable evidence of glacial action in a boulder 
bed which, though underlying strata of Cretaceous age, and 
formerly supposed to belong to that period, has lately been 
proved to belong to the horizon of the speckled sandstone 
(upper Coal Measures) of the western portion of the range. 
This knowledge originated in the discovery by Dr. H. Warth, 
in 1886, 3 of fossiliferous concretions in a gravelly layer over- 
lying the boulder beds of the Olive group. These concretions 
contained eleven species of invertebrate remains, among which 
were the genera Conularia (3 species), Aviculopecten, Nucula, 
and Spirifer. Of these eleven species four are found in the 
Australian Coal Measures and several in the Productus lime¬ 
stone of the western Salt Range. The spirited discussions 
called forth by this announcement presented a vigorous and 
brief struggle, the reports of which are still fresh in the lead¬ 
ing geological journals of Europe. Subsequent researches in 
the field, by various members of the Survey, have shown that 
the concretions are not only in place, and lithologically iden¬ 
tical with the surrounding matrix, but also that, while they
