DESCRIPTION
Test large in size and ovoid in shape with convex lateral sides and rounded poles. The initial first to second volutions coiled tightly and spherical in shape, but in the succeeding volutions the test loosely coiled and after a rapid elongation the outer shape of the test become ovoid. Proloculus globular and relatively large, with an outside diameter of 182-190 microns. The number of volutions is up to 6-6½ in advanced specimens, and length ranges between 3.15 to 3.98 mm, diameters range between 2.03 to 2.10 mm and form ratios of 1.50 to 1.96. Wall is relatively thick (0.045 -0.050 mm in the outer volutions), four-layered and composed of a tectum, a welldeveloped diaphanotheca and dark-dense lower and upper tectorium ( Fig. 14G View FIG ). Septa regularly folded throughout the test. Chomata are massive, symmetrical and quadrate in shape, and their heights reach to half height of chamber.
REMARKS
Beedeina tauridiana Akbaş , n. sp. differs easily from the other species of genus Beedeina by its characteristic ovoid test shape.
