Carboniferous Glaciation , Etc .— White. 325 
the Triassic and Jurassic, over the rest of the world. 
To show the further development and remarkable distribu¬ 
tion of this flora, I will only add two illustrations, which I 
take from the flora of the western hemisphere. The first case 
is that of the flora of the Richmond coal-field, whose relation¬ 
ship with the upper Gondwana flora was pointed'out 1 in pro¬ 
fessor Fontaine’s able monograph on the Older Mesozoic 
Flora of Virginia. Indeed Dr. Stur, the eminent phytopaleon¬ 
tologist of Vienna, to whom a collection was sent, has lately 
announced that by far the greater part of the flora of that 
field, (which he considers the equivalent of the upper Trias, 
“ Lunzer,” of Europe), is identical with the flora of the older 
mesozoic of Germany, France, and Scandinavia, and forms a 
branch of the phyllogeny, escaped from the Indian continent 
through the south of China. The second instance to be 
noted is the general Glossopteris-flora aspect of the mesozoic 
of South America, especially that of the Argentine Republic, 
regarded by Geinitz as Rhetic, though the species were largely 
new. But a most suggestive, and perhaps significent flora is 
the strange company which was found by Dr. Rudolph Zuber 
at Cacheuta, in the province of Mendoza, and which was sub¬ 
mitted by him to Prof. Szajnocha for study. 2 The importance 
of its bearing on the possiblity of paleozoic glaciation in 
South America is my apology for the details introduced, 
though it is perhaps still too early to attempt to draw any 
conclusions, or to go farther than to make the suggestions 
which present themselves naturally. Of the twelve species 
found there, Sphenopteris elongata Carr, has also been re¬ 
ported from the coals of Queensland; Pecopteris Schdnleini- 
ana Brgt.,from the Newcastle mines of New South Wales and 
the “ Lettenkohl ” of Wurzburg ; Thinnfeldia odontopteroides 
Morr., from the Queensland coal, Jerusalem basin, Van Die- 
mensland, and the Stormberg in South Africa; T. lancifolia 
Morr., from Jerusalem basin; IV europteris aff. remota Presl., 
from the Keuper of Europe; Schizoneura hoerensis ? Hising,
