Material. - Over 300 specimens (Coll. No. F-121)
Dimensions: Initial part L 0.1-0.2; uniserial part L up to a few millimetres.
Description. - Initial part irregular, composed of 2-5 chambers arranged
planispirally initially, then in a triloculine or quinqueloculine way;
uniserial part with numerous robust spherical chambers, closely adherent
to each other, of which younger chambers often overlap (PI. XVII, Fig. 11);
sutures fairly broad, with irregular indentations (PI. XVII, Fig. 12);
surface rough, with irregular, transverse undulations and longitudinal
wrinkles; aperture large, circular, surrounded with a thickened rim,
without tooth.
Variability and ontogeny. The shape of chambers of the uniserial part
is variable, initially spherical, then more inflated at the base. The surface
ornamentation may be more or less distinct.
Remarks. - This species differs from Articulina problema Bogdanowich
in its more compact, spherical chamber shape. From A. multibullata
n. sp. it differs in lacking irregular protuberances on the inflated and
overhanging part of chambers.
Distribution. - Poland: Lower Sarmatian (Budy, Dwikozy, Grzyb6w,
Mokrzysz6w, Zrecze). Austria: Sarmatian, vicinity of Vienna, Vienna
Basin. Romania: Lower Sarmatian, Moldavian Platform. USSR: Lower
