Sp. Char. — H. foliis impari-pinnatis, foliolis lateralibus subsessilibus, 
submembranaceis, lanceolatis, basi obliquis, margine grosse spinoso-dentatis,

prominente ; nervis secundariis tenuibus, subangulis acutis variis orientibus,

marginalem formante, postico craspedodromo ; nervis tertiariis rectangularibus 
dictyodromis, maculis ultimce ordinis apertis. 
Ohs . — We have only a mere leaf-fragment before us, yet it exhibits 
sufficient characters for its determination. The leaf is pinnate ; the leaflets 
are lanceolate, their borders spinously dentate, their base oblique, a little 
narrowed, sessile or by a very short petiole joined with the racliis. The 
texture is somewhat tender, almost membranaceous. The nervation repre- 
sented in Pig. 7a, magnified, is partly well-preserved. A strong primary 
nerve sends out thin secondary ones at varying angles of divergence being 
mostly a little acute. Close to the borders each of them divides in two 
branclilets, one of which, namely, the anterior, runs up the margin to 
anastomose with the nearest secondary nerve, whilst the posterior one runs 
towards the margin, reaching the nearest tooth. The rectangular tertiary 
nerves form a network agreeing in its open meshes with that of the preceding 
species. 
Locality and Horizon . — Old Rose Valley Lead, with the preceding.

Sp. Char. — L. foliis coriaceis, petiolatis, lanceolatis, basi subacutis vcl 
obtusis, apicem versus angustatis, acuminatis, margine grosse spinuloso- 
dcntatis ; nervatione brochidodroma; nervo primario prominente, recto, apicem 
versus attenuato ; nervis secundariis tenuibus, subangulis 50-60° orientibus, 
approximate, ramosis inter se conjunctis; nervis tertiariis e latere externo 
secundariorum subangulis variis acutis obtusisque egredientibus, ramosis, 
rete macrosynammatum formautibus, reticulo evoluto. 
Ohs . — This species differs from the following ones by the base of its 
leaf being a little narrowed or sometimes roundly obtuse, and by its deeply
