448 Br. F. Kurtz — The Fossil Plants of Argentina. 



Lepidophloios of the northern deposits, distinguished stratigraphically 

 by Bodenbender (who will put forth his views in two memoirs— one 

 in our Boletin, with a number of sections: the other in German 

 accompanying a paper hy Professor E. Kayser, describing the 

 Devonian fossils collected by Bodenbender). The little diagram 

 (Table A) at the end will perhaps explain the state of the flora 

 better than my description. 



From Cacheuta, in the province of Mendoza. we have received 

 two beautiful collections of fossil plants made under the direction of 

 Mr. E. Glaser, formerly Director of Petroleum Mines at that place. 

 We had also smaller collections made by Dr. L. Brachebusch and by 

 Dr. Bodenbender. 



The principal species of this deposit are : — 



Dancea, sp. nov. (a splendid fern). 



Aspleninm Whitbyense (Brong.), Heer (not rare). 



Sphenopteris elongata, Carruthers (rather common). 



Thinnfeldia odontopteroides (Morris), Fstm. (abundant). 1 



lancifolia (Morris), Szajn. (abundant). 



Bravardia Mendozensis, Hanthal (perhaps the fruit-bearing state of 

 a Thinnfeldia, the only indusia visible quite re- 

 sembling those of Aspidium, sect. Polystichum). 



Pecopteris tenuis, Schouw. 



Oleandridium Mareyesiacum (Gem.), Kurtz (not rare). 



sp. nov. (common). 



Podozamites elongatus (Morris), Fstm., var. latior, Fstm. (common). 



Zamites, sp. nov. 



Sphenozamites, sp. nov. 



Pteropliyllum, sp. nov. (ex off. P. Camalliani, Gopp., rather 

 common). 



Baiera, sp. nov. (common). 



Cardiopteris Juberi, Szajn., justly removed from this old Culm genus 

 by Nathorst (Ptilozamites, Z. Kath.), proves to be 

 nothing but a little curious form of Thinnfeldia 

 lancifolia, Szajnocha. As you remarked in the 

 " Records," the character of the Cacheuta flora 

 is Australian and African, and has hardly anything 

 in common with the higher Indian Gondwana floras. 

 The last discovery of fossil plants, made by Dr. Jose A. Salas, of 



Mendoza, a very zealous examiner of coal-mines in the Cordillera, 



furnished me with a small collection of types, derived from the 



mines of "Del Transito " on the Rio Atuel (southern part of the 



province of Mendoza), which prove the existence there of something 



like a Rajmahal flora. The plants I have been able to determine 



up to the present are as follows (in the same region were found 



Liassic animals) : — 



Aspleninm Whitbyense (Brong.), Heer. 

 Macroteniopteris, sp. 



1 The Thinnfeldia odontopteroides of the Upper Gondwtmas is — as far as one may 

 judge from the drawings in the Gondwana Flora (Pal. Ind.) — rather a doubtful form.
