It is a group with erect, usually barrel-shaped zocecia :— 
I. With a pit towards which the zocecia are directed, 
1867, Barovora, Rss.—Oral aperture small (0:09 mm.), nearly round, 
but examination shows straight lower edge. Bi-laminate. Primary 
zocecia hidden. Type, B. stoliczkat, Rss. (probably young of B. multi- 
radiata, Rss.). 
186i. OrBrruLipora, Stoliczka.—Oral aperture large, with straight 
lower edge. Pit at the side. Bi-multilayered. Type, O. hardingeri, 
Stol. 
1881. SeHaRrorHora, Haswell.—Oral aperture large (0:12 mm.), 
with straight lower edge. Grows in all directions from the early 
zocecia, Pit central. Multi-laminate. Type, S. fossa, Haswell. 
1852. StrcHoOPORINA, Stoliczka.— Oral aperture small. Uni-laminate 
to bi-laminate? Pit central. Type, S. rezssz, Stol. 
II. Usually without a pit. 
1873. Mamitiopora, Smitt*.—Oral aperture large (0:12 mm.), con- 
tracted at each side. Primary zocecium erect, surrounded by six similar 
zocecia. Only uni-laminate, showing the position of the zocecia on the 
under surface. Type, M. cupola, Sm. Tertiary fossils: M. simplex, 
Kosch., M. bidentata, Rss., M. protecta, Kosch. 
1851. CoNESCHARELLINA, d’Orb.—Oral aperture very small, slight 
sinus, opercula with muscles some little distance from the border, semi- 
lunar slits. Cone uni-laminar, filled in by large chambers. (‘To be dealt

from N: Italy has large pores round the apex, and one near the centre is
