reference to the contemporaneous deposits in Argentina which affor- 
ded the data most essential in showing the presence of the Glosso- 
pteris (Lower Gondwana) flora in the western hemisphere. 
In 1894 professor Kurtz, of the University of Cordoba, published (1) 
a paper, «Sobre la Existencia del Gondwana Inferior en la Republica 
Argentina,» in which he records the presence of Neuropteridium 
validum, Gangamopteris cyclopteroides Equisetites Morenianus (2) 
Sphenozamites multinervis (3) Neeggerathiopsis Hislopi varieties sub- 
rhombotdalis and euryphylloides, and Walchia sp.* 
The beds in which they occur at Bajode Velis, providce of San 
Luis in Argentina, are considered by him as probably Karharbari and 
Permian in age. This paper is taken into account by Zeiller in his 
article on the coal flora of Rio Grande do Sul, already cited, (4) where 
Kurtz’s Noeggeratgiopsis Hislopi var. euryphylloides is referred to 
Luryphyllum, his Sphenozamites being regarded as belonging to Noeg- 
gerathtopsis. : 
In the same year, 1896, Bodenbender (5) published a description 
af the coal formations of Argentina in which he notes occurrance of 
fossil plants at several points. Hestates that among the latter pro- 
ressor Kurtz had preliminarily identified not only most of those enu- 
merated in the paper just cited, but also Glossopteris sp. This, he 
says, is the first discovery of the latter genus in South America. Bo- 
denbender’s paper was followed,in 1896, by the publication by Zeiller(6) 
of a part of a letter from Kurtz in which the latter announces the 
accumulation of aconsiderable collectian from Bajo de Velis, inclu- 
ding Noeggerathiopsis Hislopi, Gangamopteris cyclopteroides Rhi- 
pidopsis ginkgoides, Rhipidopsis densinervis, and Equisetites More- 
nianus. Headds that Bodenbender had found, in the Llanos moun- 
tains of the southern part of the province La Rioja, abundant specimens 
of Glossopteris with Neuropteridium validum, Sphenopteris sp., 
Equisetites, several forms of Phyllotheca, Cyclopitys dichotoma, Noeg- 
gerathiopsis, Waichia, etc. ; and that, at Trapiche, near Guandacol, 
in the northern part of La Rioja, Neuropteridium validum had been 
found associated with a Lepidophyte probably belongig to Lepidophloios
