DESCRIPTION
Test relatively large in size and inflated cylindrical to ovoid in shape with convex lateral sides and rounded poles. All volutions are loosely coiled. The initial first volution is spherical in shape and in succeeding volutions test begin to elongation and ovoid in shape in the outer volutions. Proloculus globular and moderately in size, with an outside diameter of 100- 150 microns. The number of volutions is up to commonly 5 in advance specimens, and length ranges between 2.80 to 2.90 mm, diameters range between 1.70 to 1.80 mm and form ratios of 1.56 to 1.71. The four-layered wall is thick (0.045 -0.060 mm in the outer volutions), and is composed of a thin tectum, a prominent and thick diaphanotheca, dark lower and upper tectorium ( Fig. 18E View FIG ). Septa intense and folded throughout to the coiling axis of the test. Chomata are massive, symmetrical and rounded in shape.
REMARKS
Fusulinella propriaforma Akbaş , n. sp. is similar to Fusulinella propria but differs by more rounded poles.
