Extra details from original publication
Remarks - This species differs from both T gemma and T. clemenciae in possessing a fully extended extraumbilical-peripheral aperture and five or more chambers in the final whorl and a flattened to concave spiral side. The aperturallip in T neociemenciae, unlike in other forms, develops towards the periphery. In Trinidad sections, T clemenciae ranges through the lower and upper Oligocene interval.
