Stenotrema turbinella (Clench and Archer, 1933) Little Turban Slitmouth |
|
|
| Drift, Paint Rock River, Butler Mill, Marshall County, Alabama, 3/22/2019 (9.1 mm.). Collected by Bob Winters. This form is squatter and less globose. From S. stenotrema it can be distinguished by the more inflexed parietal tooth and less broad, deeper interdenticular sinus. That species, as well as S. nudum, S. sp. cf. S. magnifumosum, and S. sp. cf. S. stenotrema as herein treated, all have more convex bases. |
