). In early growth stages the angle is as high as 7°, but it continuously decreases with increasing conch diameter. The position of the siphuncle is preserved in specimens PMU 26814–26815 (SPR 0.49, 0.46), 26810 (SPR 0.4), 26823 (SPR 0.43) and 26826 (SPR 0.44). In smaller specimens the siphuncle is more eccentric, but in all other specimens it is nearly centrally positioned. The septal spacing varies between 0.3 (PMU 26815) and 0.44 (PMU 26826) of the corresponding conch height.
