From the Demissa bed. (Original.) mm. distant; central space with cells .45 or .50 mm. in diameter; marginal spinules in well- preserved specimens. Found in the Demissa bed, at Section 5. Paleschara amplectens. Hall. (Not figured.) (3d Ann. Rep't N. Y. State Geol., p. 7.) Distinguishing Characters. — Extremely thin incrustation, commonly on crinoid stems; quadrangular to hexagonal cells, 2 mm. in diameter; minute marginal nodes or spin- ules ; no monticules or maculae, but cells all of same size. Found in the Demissa bed, at Section 5 (rare). Genus LICHENALIA. Hall. [Ety. : From resemblance to a lichen.] (1852: Pal. N. Y., Vol. II., p. 171.) Zoarium massive, or growing in circular or flabellate expansions, eelluliferous on one side, the other covered with an epitheca. Cells arising from the epitheca, with transverse tabulae, and circular or trilobate, sometimes operculate, apertures, which are often denticulate, and have the pos- terior portion of the peristome arched and elevated. Space between apertures smooth. Intercellular spaces vesicular. Lichexalia stellata. Hall. (Fig. 66A.) (Pal. X. Y., Vol. VI., p. 195, PL LVIII.).
