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 bv a small rimule relatively 
wide and of little depth. On the margins there are two or three very . simple, 
small avicularia. 
,, , . Aa=0.09mm. 
Measurements . — Aperture 7 „ 
w=(J.0d mm. 
Zooecia 
Lz— 0.50 mm. 
fe=0.30 mm. 
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). 
Cotypes. — Cat. No. 64046, U.S.N.M.

Description . — The zoarium is free bilamellar, formed of two lamellae, back 
to back, and rarely separable ; the fronds 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 liyperstomial, 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.
