Abstract/NotesThe group of Membraniporæ, with a small median barred avicularium placed immediately above the oæcium, of which M. Griffithi, Bryd., is a leading instance, contains several Senonian members in addition to the Trimingham forms (M. Triminghamensis, M. anterides, M. humiliata) which I have already described in this Magazine. They seem to arise first in the zone of Micraster cor-anguinum.Membranipora Simulacrum, sp. nov. (Pl. XXVI, Figs. 1, 2.)Zoarium unilaminate, always adherent.Zoæcia large, very slightly subpyriform, areas oval, with average length .5 to .55 mm. and breadth .3 mm.; side walls bent slightly inwards, and so low and slender that at a hasty inspection they might be taken to be mere ghosts of some species with a low arched front wall.
