. The Norwegian North polar expedition, 1893-1896; scientific results. "Fram" Expedition. 1893-1896); Scientific expeditions. NO. 8.] DESCRIPTION OF SPECIES. 9 Sphenopteris (Adiantites) sp. d. PI. I. figs. 5, 6 and (magnified) 47, 48. Of this species three specimens are here represented, the one (wood-cut fig. 1) I only received after the plates were printed. As is seen from the drawings, the leaves are constructed as in the Adiantum, the oblique wedge- shaped leaflets being devoid of any distinct midrib and attached to the rachis by their posterior part. The anterior margin is more or less uneven. The figures will speak for themselves. The species is probably new, in so far as can be judged from this incomplete material. Of the spe- cies previously described, it somewhat resembles Adi- antites Nympharufn Heer from Bureja in Amur, (Flora foss. arctica, vol. 4), the pinnules of which are however considerably larger. Newton and Teall ^ have described two specimens from Cape Flora, bringing them under Thyrsopteris, though at the same time they draw attention to their Fig. 1. Sphenopteris [Adi- " anUtes) sp. d. in natu- similarity to Adiantites amurensis Heer. It seems '"liuS Ta'^giSifie/'"' to me that the likeness to Adiantites Nympharum is still greater, indeed, it may not be altogether impossible that they belong to this species. Whether the form described above should be considered as an earlier stage of development of the species described by Newton and Teall cannot be determined from the material at hand.. 1 'Notes on a collection of Rocks and Fossils from Franz Josef Land', etc. Quarterly Journ.
