D. 2022 – Nerinea donosa n. sp. – Gründel, Keupp, Lang and Nützel: 187, pl. 5, figs 1–5. Material. 45 specimens from Saal, illustrated specimens SNSB-BSPG 2016 XXI 1896 –1900. Description. The present new material allows a more detailed description of Nerinea donosa : Shell slender (especially early ontogenetic part) with numerous whorls; specimen 36 mm high; whorls about twice as wide as high; subsutural bulge with nodes formed very early in ontogeny; in later whorls, bulge is largely changed to a row of large nodes (8–10 per whorl); nodes extend to about half whorl height, forming narrow ramp; ramp emphasizes suture; whorl face concave between row of nodes and abapical suture are, with 1–2 slightly nodular spiral cords; strong bordering abapical spiral cord covered by the following whorl or slightly exposed above suture, covered with small nodes (not always noticeable); growth lines weakly prosocyrt, strongly backwards below adapical suture; transition from whorl face to base slightly angular at bordering abapical spiral cord; base strongly convex, conical; base with several weakly nodular spiral cords (only visible in well-preserved specimens); aperture (see Gründel et al. 2022 ) narrow with siphonal canal, with two columellar plaits, 1–2 parietal plaits and in some specimens one palatal plait; if two columellar plaits are present, the adapical one is weaker than the abapical one. Remarks. Nerinea plassenensis Peters, 1855 is more slender, the subsutural nodes are stronger, it has columellar and parietal plates ( Peters 1855 : pl. 3: fig. 12); its base has not been described in detail. Nerinea orbignyana Zeuschner sensu Peters (1855) has a series of distinct small cusps in suprasutural position, the bordering spiral cord is very strong, and it apparently has two further spiral cords on the base which are devoid of nodes.
