Remarks. Two small fragments from the Nattheim area labelled Nerinea constricta suevica were found in the collection of Quenstedt (1881-1884) of the Tuebingen Institute. They probably represent two species because they have different apical angles (one very slender, the other distinctly broader). The slender specimen is probably the one illustrated by Quenstedt (1852 : N. constricta Roemer, 1836; 1858: Nerinea constricta suevica ; 1881-1884: N. columelloides Quenstedt). Because the original material is fragmentary, poorly preserved and probably represents two species, N. constricta suevica is herein considered a nomen dubium . It is (even according to Quenstedt 1881-1884 ) not identical with Nerinea suevica Quenstedt, 1858 (see under Nerinella subscalaris Muenster , 1844 in Goldfuss).
