Description
The length of the shell is 16.3 mm, its dialmeter 5.25 mm.
(Original description) This extinct species resembles Miraclathurella gracilis but it is less slender and the whorls are shorter and revolve less obliquely. It has the same number of axial ribs and spiral threads but, as they are relatively larger, they are much more crowded than in M. gracilis. The fine spiral lines between the prominent raised threads are very minute. The lip varix is noticeably larger and the aperture is wider. The callous nodule on the body next to the sinus is much larger than in M. gracilis.[2]
Distribution
Fossils of this species were found in Oligocene strata in Santo Domingo.
