Narrimania concinna (Sykes, 1925) (Fig. 12 I-K) MATERIAL EXAMINED. — 6 sh. and 1 juvenile spm., DW130. REMARKS This species was known so far only from the Mediterranean Sea but, taking into account its protoconch indicating planktotrophic development, is to be expected also in the nearby Atlantic. Bouchet & Warén (1986) noted the similarity with the western Atlantic N. azelotes (Dall, 1927) but did not reach a decision on whether they are conspecific. Pimenta et al. (2018) reported both species from Brazil, but their specimens identified as N. azelotes (including the holotype) match the syntype of N. concinna from Sicily Channel figured by Taviani (1984: fig. 2a, b) and again by Bouchet & Warén (1986: figs 1135, 1154) for the number and pattern of spiral cords, with two prominent cords on the middle part of the whorl and an indication of a third one on the subsutural ramp. Admittedly, a large specimen (7.4 mm) from Sicily Channel figured by Taviani (1984: fig. 3) and again by Bouchet & Warén (1986: fig. 1153) has an additional fourth cord on the subsutural ramp but is still quite different from the shells identified as N. concinna by Pimenta et al. (2018: fig. 11) which show four small and evenly distributed cords and could represent an additional species. Specimens are so far too few to understand intraspecific variability and make a final decision of the possible synonymy of N. azelotes with N. concinna .
