and Ginkgo Meisteri;* while the collection from the same horizon at 
La Rinconada, a little farther north, yielded : Sphenopteris Boden- 
benderi,* Sphenopteris Fonsecae,* Cardiopteris polymorpha, Neuro- 
pteridium validum, Adiantites antiquus and Lepidodendron sp. The 
species marked by an asterisk have not yet, so far as I am aware, 
been described, and it is hoped that they may soon be fully published, 
if, indeed, the names are not already validated by description or 
illustration. 
The presence of a Rhacopteris, together with Cardiopteris poly- 
morpha,a distinctly Lower Carboniferous type in the northern flora, 
and of Adiantites antiquus in a flora characterized by a number 
of typical lower Gondwana elements is a remarkable thing, and 
merits a detailed paleeobotanical presentation. If the species are 
correctly determined and really contemporaneous, the association is of 
the greatest interest since it tends to furnish directly and conclusively 
an early date for the advent of the Gondwana flora in South America. 
More light should be thrown on the occurence, also at a point in the 
Carpinteria region, of Glossopteris ampla in apparent association with 
Bergiophyton insigne,* Lepidodendron cf. australe and Archaeocalami- 
tes scrobiculatus, as listed from the specimens collected by Sr. Fonseca. 
Kurtz identified Sphenopteris Bodenbenderi* and Phyllotheca deli- 
quescens in the fossils from the village of Famatina, while, in the 
collections from near La Pena in the Central Sierra, he finds: 
Neuropteridium validum var. Argentinae,* Pachypteris riojana,* Glos- 
sopteris retifera, Glossopteris indica, Aphlebia sp., Phyllotheca deli- 
quescens, Phyllotheca leptophylla,* Annularia argentina’, Noeggera- 
thiopsis Hislopi var . cuneifolia, and Cyclopitys dichotoma. The number 
of Northern Carboniferous species in South America is further incre- 
ased by the discovery of Lepidodendron selaginoides and Lepido- 
dendron veltheimianum at Saladillo, and Lepidodendron aculeatum at 
Amano. The occurrence of these additional Northern types in the 
Gondwana province is in itself full of interest; but it is important 
both that the stratigraphical relations of these Lepidodendron beds 
to the Glossopteris and Gangamopteris heds should be determined, 
and also that the extraordinary associations indicated in the lists 
from the Cruz de Cana and La Rinconada should he fully validated.
