In his valuable monographic memoir (1) on « the Glossopteris 
Flora » Professor Arber has, after a careful revisory study, given a full 
synonomy of the species of the genus Noeggerathiopsis, in which he 
refers Dana’s Noeggerathia spatulata and media to Noeggerathiopsis 
Hislopi. After examining the type of Dana’s Noeggerathia spatulata 
(2) Iam disposed to believe that Feistmantel (3) is justified in reco- 
gnizing the distinction of the latter species, to which he adds Dana’s 
Neoggerathia media (4). It is distinguished by the triangular, su- 
bacute apex of the leaf. 
Localities: Rare in the material from the plant bed 55 meters 
above the granite, or 225 meters below the Iraty black shale, north- 
east of Minas, Santa Cathrina. Lots 3586 and 3921. Also Estrada Nova 
near Minas,; about 135 meters above the granite, and 145 meters 
below the Iraty black shale. Lote 3923. Also from the Barro Branco 
coal, Estrada Nava, near Minas ; about 175 meters above the granite. 
Lot 3589. Abundant in the laminated coaly shale from theS. Jeronymo 
coal near Candiota, Rio Grande do Sul. Horizon about 20 meters above 
the Irapua coal. Lot 3924.

This genus contains flattened, bilateral seeds, lenticular in 
crossection and generally cordate, reniform, oval or nearly round 
in contour and more or less distinctly cordate at the base. The 
fossils usually exhibit two seed coats, a resistent sclerotest, which 
surrounds the nucellus or its cast, and an outer fleshy sarcotest or 
episperm, which is often thickened greatly toward the upper end 
of the seed, laterally dilated in the alate forms, and incised or 
narrowly emarginate at the apex. When the sarcotest becomes 
developed as an extensive very thin wing, often of relatively large 
dimensions, it is frequently designated as Samaropsis, The latter, 
when the wing is membranaceous is recognized as a distinct 
genus by some authors.
