SCHIZOPODRELLA ? MARGINATA, new species. 

 Plate 44, figs. 11, 12. 



Description. The zoarium is free, bilamellar, with much compressed fronds. 

 The zooecia are distinct elongated, rhomboidal, separated by a prominent thread; 

 the frontal is flat and formed by a tremocyst with small pores. The aperture is very 

 small and semilunar, its proximal border is intersected by a small rimule relatively 

 wide and of little depth. On the margins there are two or three very simple, 

 small avicularia.

Affinities. This species is characterized by its very small dimensions. It 

 differs from Buffonella microstoma in the presence of .the frontal tremocyst and 

 in its free zoarium. 



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

 North Carolina (very rare).

Description. The zoarium is free bilamellar, formed of two lamellae, back 

 to back, and rarely separable ; the Ironds are wide, flat, or undulated. The zooecia 

 ,are very long, fusiform, or cylindrical; the frontal is convex and formed of a 

 tremocyst, with numerous pores in quincunx. The apertura is semilunar, trans- 

 verse, with a straight proximal border, with a very small linear rimule; the peri- 

 stome is very thin and hardly salient. The ovicell is hyperstomial, much embedded 

 in the distal zooecia, quite large, globular, salient, 'smooth ; its orifice, placed much 

 above the apertura, is very large. Near the apertura, there is a triangular avicu- 

 larium, the beak directed toward the exterior.
