Naticopsis scintilla
Taxonomy
Naticopsis scintilla was named by Girty (1915) [Measurements of holotype from Knight 1933b p. 374.]. It is a 3D body fossil. Its type locality is Station 429. 6th and Bluff streets, Kansas City, which is in a Missourian carbonate limestone in the Drum Formation of Missouri.
It was recombined as Naticopsis (Jedria) scintilla by Yochelson (1953).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. B. Knight 1933 | Moderately large, neritiform gastropods, which at adult stages have a very broad, shallow and somewhat obscure spiral groove or flattening passing around the upper half of the whorls, this concave or flattened band bounded by the somewhat swollen or slightly shouldered subsutural region and a rounded ventricosity a little below mid-whorl height, shoulders set off from the spire by well marked, but not deep sutures and either without sculpture or with only a faint fasciculation of the growth lines near the suture; parietal inductura thickened, somewhat flattened and extended in the plane of the aperture.
N. scintilla differs from both N. ventricosa and N. meeki in that the revolving groove is more obscure, the shouldering of the whorls less strongly developed, the sutures shallower and in that the costae on the shoulders are very weakly developed, or even entirely lacking. The shell as a whole is more rotund, is smoother and less angular than in either of the other two species. At neanic stages the spire of N. gigantea is noticeably higher and the sutures shallower than in the same stages of the compared species. |
