short, finely denticulated, ninnbering three or four; they are irregular and their 

 position never symmetrical. The zoarium is rather variable. The small specimens 

 are always wider than high. The large specimens are cupuliform but always very 

 convex. 



This species differs from Cupularla haidingeri Keuss, 1847 ( = C. denticulata Busk, 

 1859), in the smaller micrometric measurements and in the absence of the large 

 hydrostatic tuberosities of the internal face. It differs from Cupularia reussiana 

 Manzoni, 1869, in its spinous processes never united. It differs from Cupularia doma 

 D'Orbigny, 1851, which it most resembles in its large, thin, cupuliform zoarium 

 and in the absence or attenuation of the large tuberosities of the internal face. 



Occurrence. — Miocene (Duplin marl) : Natural Well, 2 miles southwest of Magno-
