Genus CRIBRICELLINA Canu and Bassler, 1927 (Cribricella Levinsen, 1909, preoccupied) The ovicell is a terminal gonoecium. The operculum has a straight or but slightly curved edge. The operculum of the gonozooecium much wider, has a straight proximal edge. The sternal area has numerous scattered pores, of which the outermost are arranged in a dis- tinct curved line, and a small transversely oval cryptocyst lam- ina on its inner sur- face. The hinge-teeth are rudimentary or indistinct. Genotype.—Cri bri- cella (Catenicella) rufa MacGilli vray,. Fig. 181.—Genus Catenicellopsis Wilson, 1880, and Genus Digenopora Maplestone, 1899 A, B.

Genus CALPIDIUM Busk, 1852 The ovicell is a terminal gonoecium. The operculum has a sinus. The operculum of the gonozooecium much wider, has a straight proxi- mal edge. The sternal area has 5 fenestrae. The aperture, the anter of which is surrounded by a strongly projecting margin, has a trilobed or triangular sinus ending in a point, and is provided with two very strong hinge teeth, projecting within the aperture. The septulae of the lateral chambers are placed in small rounded depressions. Genotype.— Calpidium ornatum Busk, 1852. Range.—Miocene of Australia. Recent. Genus STROPHIPORA MacGillivray, 1895 The
