Plates in five imperfect cycles ; calice elliptical; ribs notched above, granulous below. GENERAL DESCRIPTION. Corallam. Slightly turbinate, adhering by a base broader than any other part, a little diminishing towards mid-height, and widening gently above and below. Wall thin. Height about equal to the medium diameter. Ribs. Distinct from base to margin; on the upper half prominent, thin, with a rather sharp, but irregularly notched edge, separated by inter- costal furrows of about twice their width ; on the lower half forming low rounded ridges, crowned with conical granules, set in two or three irregular longitudinal rows; all are nearly alike in every respect. Calice. Elliptical; the axes as 24 : 31. ^\magnifiedj. Plates. Forming five cycles and six systems ; ^ portion cut away to but those of the fifth cycle are wholly wanting show the plates. in three systems, and present in both halves of the other three. Not very close-set, not very salient, thin, very little thick- ened externally, the highest point of their edge a little within the margin, whence it slopes very slightly inward and downward, in an undulate line, ending with an abrupt angle, whence the inner edge descends perpendicu- larly : the entire edge rises into irregular eminences and blunt points, and both surfaces are roughened with coarse granules. Columella. Formed of two or three much twisted lamellae, with broad rounded lobes, rising from the united pal ides. Palules. Thin, waved, lobed and granulate, like the septa; those of the tertiary septa large ; the others inconspicuous, and only here and there discernible ; united in the centre into an irregularly waved and perforated horizontal plate.
