Original Description

Gorbachikella grandiapertura differs from G. kugleri in having a very convex spiral side, five chambers in the first whorl which reduces to four chambers in the whorl in the last two whorls (instead of only four chambers in each whorl throughout the test) and an axiointraumbilical aperture but with a much higher symmetrical (see Pl. 4 , fig. I b-2 b) to slightly asymetrical arch (see PI. 4 , fig. 3a, 4 b, 5a).
