Found in the "'Hamilton group, at Eighteen Mile Creek, Erie County, X. Y.," also "West Hamburg, Erie County, ; (Hall.) Fistuliporina micropora. (Hall.) (Fig. 63.) (Pal. X. Y., Vol. VI., p. 220, Pis. LVIL, LIX.) Distinguishing Characters.— Thin, lamellate expansion of frond, incrusting crinoid stems, etc.; vesiculose intercellular tissue; broadly oval to nearly circular irregularly disposed cell apertures, with thin, smooth peristomes, ranging from con- tact to a cell-diameter apart; minute meso- pores (about ten in space of 1 mm.) in one, rarely two, series between apertures, their margins equal in elevation to the peri- stomes; general delicate appearance of surface of frond. Found in the " Hamilton group, at Eight- een Mile Creek, Erie County, N. ; (Hall); and also in the "Hamilton group, at West Hamburg, Erie County, X. ; (Explanation of plates.) Fistdliporina minuta. (Rominger.) (Fig. (54.) (Pal. N. Y, Vol. VI., p. 222, PL LIX.) Distinguishing Characters.— Thin, lamellate expansion of frond, which is free or incrusting; very thin, concentrically wrinkled epitheca; irregularly disposed,comparatively large vesicles occupying the intercellular space; oval to obscurely.
