Acidaspis cerelesta, Ohio Pal. Vol. I, pl. XIV. fig. 8 = Ceratrus according to Miller (= Ceratrus pleurixanthemus acco- ding to him) Parcedus Darwini: Fragments and few specimens are rare in hills back of Cincinnati, about 40 feet up. = Belleme or base of Corys- mille. Corryville rather near top. Good specimens = 2 mi S of Mayo- vil(le), in a layer of sand 2 feet thick between harder stratified rocks. base of Bellevne. = Fig. 1 A B of plate I of mine, Parcedus clauderi, Miller, Diametra ½ to ¾ in. Diameter of depres- sions = about ⅓o inch. Parcedus is placed by Kindl under sponges. Plate I. Parcedus darwini. (Sponge palaezo) Coryville Found two feet clay layer at base Corryville, about two miles south of Mayerville. R in railroad cut. Depressed globular bodies, portably originally nearly spherical, with depressions, chiefly for a spind, originall filled by plate which were a little con- cex on the inner surface. Frag- ments and few specimens are rare in hills back of Cincinnati, at 400 ft (= Corryville?) Outcrop at top of section at 425 ft. Parcedus clauderi, Miller, ½ to ¾" diam of specimens, ⅓o in = diameter of depressions. Found associated with P. darwini at Mayerville- (= Base of Bellevne) but not at Cincinnati. Dabruamella cyclo is less robust shell than multitecta; valves very thin, hence the ventral valve appears nearly flat in most specimens, except near the beak and along the slight marginal ridge, due to pressure flattening. Radiating striae said to be prominent and rather coarse, less fine than those of multitec- tecta, but this is not true of the type in the James collection.
