CARBONIFEROUS. 03 



pinnules have somewhat the character of Cardiopteris, or Odontopteris, in 

 which genus Mr. Carruthers originally placed his specimens. 



The fossils presented by Mr. Wilmot unfortunately do not bear any note of 

 the locality from which they were collected. 



We see in this species a similar change in the segmentation of the pinnules 

 to that occurring in Sphenopteridium dissectum, Goppert, sp. 



Horizon. ? Coal Measures. 



Locality. Brazil : Rio Grande do Sul (type specimens).

Remarks. The Collection contains a fine specimen from Glencartholm, 

 which is 14 inches long, but only attains a width of rather less than \\ inches 

 at its broadest part.

Gomes, Flora Foss. do Terr. Carbon, do Porto, Serra do Bussaco, p. 32, 

 pi. ii. figs. 1, 2, 1865. 



Remarks. This species was described from a very fragmentary specimen, 

 which showed only a small part of a pinnule, but it gives the characters 

 sufficiently clearly to enable one satisfactorily to identify the Burdiehouse 

 fossil as the same species. 



Description. Pinna3 alternate, pinnae segmentation unilateral, segments, 

 linear, narrow, one vein passing into each lobe. Rachis thin. 



The plant described by Gomes as Noeggerathia, sp., appears indistinguishable 

 from Rhacopteris flabellata, Tate, sp. 



Schimper* unites Gomes' plant with Rhacopteris elegans, but this latter
