Description
editThe height of the shell attains 16 mm, its diameter 5.4 mm.
(Original description) The shell is small and slender, with a protoconch consisting of about two and a half whorls. The stromboid notch is rather deep, as indicated by the growth lines, while the siphonal notch is moderately deep and asymmetrical. The sculpture features narrow axial ribs that are weakly overridden by very fine, widely spaced spiral threads. The anal fasciole is flat, adorned with curved, attenuated prolongations of the ribs and finer, more closely spaced spiral threads than those found on the rest of the whorl. [1]
Distribution
editThis extinct marine species was found in Pliocene strata on Jamaica.[1]
