Species Morozovella inconstans Subbotina 1953


Discussion / Comments:
Toumarkine & Luterbacher (1985):
The low trochospiral test has 5 to 6 globular chambers in the last whorl increasing fairly gradually in size,and a wide and shalow umbilicus. The spiral side is flattened with the small early portion of the test slightly depressed. The sutures are depressed. Morozovella inconstans differs from M. trinidadensis by its globular chambers without any diferentiation in the ornamentation and by the generally smaller number of chambers in the last whorl.
