Plate X. Fig. 6. 



Specific Character. 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.
