Four new species of petrified seeds are described:
1. Eccroustosperma langtonense gen. et sp. nov.—a curved platyspermic seed with two apical lobes of the integument and a rough sclerotesta when mature.
2. Hydrasperma tenuis gen. et sp. nov.—a small slender seed with 8–10 free apical lobes and longitudinal external ridges.
3. Stamnostoma bifrons sp. nov.—a barrel-shaped seed with a nucellar apex and micropyle intermediate in form between Stamnostoma huttonense and Sphcerostoma ovale.
4. Dolichosperma sexangulatum gen. et sp. nov.—a relatively long narrow radiospermic seed with a dense sixangled integument open above and without tentacles or micropyle. The salpinx was probably funnel-shaped.
All four species are assigned to the Lagenostomales.
