Possibly, when better material is discovered, it will be necessary to separate those larger fronds as a separate species; for the present the specimens available are hardly sufficiently distinct to admit of more than a convenient descriptive term, such as var. Saporta has already used the same word as a specific title, but we may use it in this instance in a less precise sense and iu- dicative, at the same time, of a close resemblance to his Jurassic species, T. superha, Sap.^. Fig. 14 (V. 2729a). Fragment of a frond of Tcmiopteris Beyrichii (Schenk), var. superba, V. 2729fl!. Fig. 14. Thirty-four cm. long; apparently half of the lamina of a large simple frond. On one side of the half lamina there is the remains of a midrib, from which the closely set lateral veins are given ofi horizontally. Where small patches of a carbonaceous film occur on the surface of the specimen one can detect very fine lines running between, and parallel to, the lateral veins. Breadth 2'7 cm. at the broadest part. Ecclesboume. Rufford Coll. v. 711. The prominent midrib represented by a deep groove, lateral veins closely arranged. Length of specimen 7'5 cm., 1-2 cm. broad, about the same width as the figured specimen of T. Beyrichii, PL IX. Fig. 3, but the veins are much closer and more numerous. Ecclesboume. Rufford Coll, V. 2380. Portion of a large frond. Venation well marked. Cf. V. 2729fl (Fig. 14). Ecclesboume. Rufford Coll. ' Pal. Fran9. vol. i. pi. Ixii. fig.
