MILIOLIDAE' FROM MIOCENE OF POLAND 97
chamber arrangement, the chambers increase gradually in size and have
a transverse oval shape; PD 30fL (Text-fig. 34/1).
Remarks. - Karrer described two similar species from Lapugiu: Quinqueloculina
fabularoides and Q. transilvaniae, making no mention of their
agglutinated test. They differ in that Q. fabularoides has a trematophore

stage, 8, 9 - sigmoiline stage.
aperture and Q. transilvaniae a circular one with a simple tooth. In the
topotypic materials from Lapugiu de Sus numerous specimens corresponding
to both species were found; it is however not possible to differentiate
them into two distinct species on the basis of their morphology. It may
well be that Karrer used the name Q. transilvaniae for specimens with
the damaged trematophore, such specimens being frequent in the material
from Lapugiu. Our specimens correspond to the topotypes from Lapugiu,
there is however no reason to distinguish the specimens with the trematophore
destroyed, or the juvenile specimens with the trematophore as yet
undeveloped, as separate species.
Distribution. - Poland: Upper Tortonian (Niskowa). Romania: Tortonian,
Lapugiu de Sus. USSR: Middle Miocene, the West Ukraine.
