v1881-1884 - Nerinea teres Goldfuss - Quenstedt: 540, pl. 206, fig. 26.

Remarks.

The material representing Nerinea teres studied by Quenstedt (1881-1884) consists of five poorly preserved fragments. The best preserved one is figured here in Plate 19 : fig. 5 ( Quenstedt 1881-1884, pl. 206, fig. 26). It consists of about three whorls and is 12 mm high. Its whorl face is straight and ornamented with four equally strong spiral cords without knobs. The distance between the second and third spiral cord is larger than the distance between the other cords. The sutures are barely impressed. The specimen illustrated by Quenstedt (1881-1884, pl. 206, fig. 25), which is of uncertain species identity, has a canal, two columellar plaits, and a parietal plait. The morphology of the outer lip is unknown. The fragment illustrated cannot be assigned with certainty to any of the species described herein.
