Genus STENOSIPORA Canu and Bassler, 1927 



The zoarium is cupuliform. The inferior base of each zooecium is 

 hexagonal and porous. The superior base is little convex, perforated 

 in the middle by the aperture and often decorated laterally by one or 

 two avicularia. The aperture is elliptical with two cardelles placed 

 more or less low. The ovicell is hyperstomial, closed by the oper- 

 culum, embedded in the distal zooecium; the ovicelled zooecia are 

 no larger than the others. 



Genotype. — Stenosipora (Stichoporina) protecta Koschinsky, 1885. 



Range. — Eocene (Lutetian, Priabonian).

1885. Kionidella Koschinsky, Beitrag zur Kenntnis der Bryozoenfauna der 

 alteren Tertiiirschichten des Siidlichen Baycrns, Palcontographica, vol. 

 32, p. 67. ( = Discojluslrellaria D'Orbigny, 1853.) 



The zoarium, rarely cupuliform, is principally cylindrical, conical at 

 its extremity and much elongated. The inferior base of each zooecium 

 is fusiform and decorated by a large distal septula. The superior 

 base is convex, perforated in the middle by the aperture and decorated 

 laterally by two triangular avicularia with the beak converging toward
