laricinus Kurtz concludes that in the latter region we havea ming- 
ling of. northern and southern types similar to that in Rio Grande do 
Sul in Brazil, and that in both districts the beds are probably Permian. 
Zeiller’s discussion of this communication in connection with a 
more extended commentary on Schamalhausen’s Altai flora, séems to 
be nearly contemporaneous with another paper by Bodenbender (1) con- 
taining a stratigraphical discussion of the plant beds of the Sierra de 
S. Luis, Sierra de los Llanos, and Sierra de la Rioja, from Which are 
recorded: Neuropteridium validum, Glossopteris communis, Glossopte- 
ris retifera,Gangamopteris cyclopterotdes, Phyllotheca sp., Equisetites 
Morenianus, Lepidodendron Pedroanum, Lepidodendron Sternbergii, 
Noeggerathiopsis Hislopi, Euryphyllum Whittianum?, Rhipidopsis 
ginkgoides, Rhipidopsis densinervis, and Cyclopitys dichotoma. After 
discussing the stratigraphical equivalents in these ranges of the beds, 
which he correlates with the Karharhbari, Bodenbender further argues 
that a part, at least, of the plantbearing series may he pre-Permian. 
The stratigraphical relations of the plant-bearing terranes, so far 
as ascertained in Argentina, are discussed much more fully in an 
article entitled « Devono y Gondwana en la Republica Argentina », 
published (2) in 1897 by Bodenhender, who traced the Permo-Carho- 
niferous for a long distance along the Cordillieran foothills. It 
appears thal in this region, as well as in southern Brazil the 
Palaeozoic plant beds and coals are immediately overlain by red beds 
of supposed Triassic age, The geological data relating to the older 
Gondwana flora are augmented in an important way by Bonden- 
der in another paper describing the formations in the « precordillera » 
of the provinces of San Juan and Mendoza and in the central sierras 
of the republic, (3) published in 1902. 
In this, as in Bondenhbender’s former papers, the plants were 
named on the autority of professor Kurtz. The fossils from the 
vicinity of the Cruz de Cana mine, in the Carpinteria region, include, 
according to Kurtz: Sphenopteris (Asplenite) Maesseni,* Sphenopteris 
Salamandra, Sphenopteris sanjuanina,* Rhacopteris Szajnochai,* 
Glossopteris Browniana, Gangamopteris cyclopteroides, Cordaites (2),
