 pyriform with a short gymuocyst : the mural rim is prominent, flat, oblique. granu-

 the opercular valve. The small pedicellated avicularinm is slightly projecting 

 and rounded.

The figured specimen represents the area about the ancestrula, and 

 the marginal zooecia are alone considered ns normal. We have observed some 

 zooecia with the mural rim double, which in consequence have undergone total 

 regeneration. 



This species differs from Ranii>l><ii,i>ht.<< 1, : //* in its granular mural rim which 

 has somewhat the aspect of a collar of pearls. 



Occurrence. Middle Jacksonian (Castle Hayne limestone): Wilmington, 

 North Carolina (very rare).

 the mural rim is thin, salient. /<//"'<" The opesium in anterior, oval, very finely 

 crenulated. The ovicell is hyperstomial. never closed by the opercular valve: 

 globose, projecting, with a large frontal callosity, granular. The median avicu- 

 larinm is very salient, transverse, and its orifice is perpendicular to the zooecial 

 plane. The ancestrula is a very small zooecium of the ordinary kind.

s. The second calcareo.us layer of the ovicell is very small and forms 

 only a thin smooth border around it. Regenerated zooecia appear to be rare. 

 Some calcified zooecia perforated with a round pore have been noted. Figure v

Thi- species differs from both Rampkonotus frr!* and 7?. fi.irn/fiix in its large 

 dimensions and in the regularity <>t' its mural rim.
