Test free, trochospiral: globular chambers increasing gradually in size: radial deep sutures: calcareous, perforated wall, radial in structure with pitted surface; on the spiral side 10-12 chambers arranged in 2 ½ whorls; last whorl consists of 4 chambers; umbilical side covered by an apertural bulla which overlays the primary interiomarginal umbilical aperture; numerous supplementary apertures on the spiral sutures; there are also many infralaminal apertures on the apertural bulla suture.

Extra details from original publication
Remarks. Velaperrtina iorgulescui resembles V. indigena , [Globigerinoides indigena(Luczkowska) 1955] but differs from it in size as well as in the shape of the apertural bulla which is smaller and more ovoid in V. iorgulescui species."

The age given at the time of the publication considered a wrong correlation between the Mediterranean and Paratethyan stages. At that time the Badenian (where from the material comes) was correlated with the Tortonian, but later on it was correlated with the Langhian and early Serravallian). The material comes from the Velapertina Zone of the late Badenian, which means the correct age for the species is early Serravallian.

Dear Prof Filipescu

Thank you for commenting on this and I have now corrected the text.
