VIII. Eared Neuropterite. (Neuropteris auriculata, Brongniart. Hist. Veg, Foss, tab. 66.Filicites Osniunda, of Artis.) The general aspect of this beautiful filicite very much resembles that of our well-knownflowering fern, the elegant Osmunda regalis; the auriculated or one-eared base of the lanceolatedleaflets forms, however, a distinguishing character. It belongs to the genus Neuropteris (nerved-leaf fern) of M. Brongniart, which comprises many species of delicately-veined ferns : the veinsin this fossil plant are very fine, arched, and rise obliquely from the base of the leaflet. The leaflets are often found detached, and in many instances, though completely carbonized, are so firm, and so slightly attached to the shale, that they may be separated by a pair of forceps: when removed, their impression remains on the stone, as is shown in the light-coloured part of the figure 2 ; the form and distribution of the rib, and nervures or veins, are seen in fig. 3. From Elsecar colliery. ll

Cheilanthites; from its supposed analogy to the recent genus Cheilanthes. Goppert.Trans. Academy of Bonn.) This is a rare species of fern from the coal shale of Yorkshire, Elsecar Colliery. It hasthe leaf or frond tripinnate; the pinnae, lobes, or wings, alternate with an odd one; the leafletsare ternate, with roundish, convex lobes. This plant has been referred to the tropical ferns, and is nearly allied to the genera Davallia,or Cheilanthes; but from the almost general absence of the organs of fructification in fossil ferns,it is impossible to refer them with any certainty to living genera. It belongs to theSphenopteres, or wedge-shaped-leaf ferns, of M. Brongniart. A, shows the cast or matrix of the under side of the leaf; b, the upper side in relief. I 1
