Species Nucula glabra Sowerby 1846


Discussion / Comments:
Griffin & Nielsen (2008):
TYPE MATERIAL. Holotype: NHM-L27966. REMARKS. Sowerby’s figure is not a nuculid. The hinge of the only specimen is not shown, but all other characters agree well with a small species of Scalpomactra Finlay in Marwick, 1928 [type species Mactra scalpellum Reeve, 1854] very abundant in the Monte León Formation and collected by us at the type locality. The species is thus referred to Scalpomactra. The specimen described by Ihering (1897, p. 244, pl. 4, fig. 24 and pl. 5, fig. 31) as Leda glabra Sowerby is something entirely different, possibly close to Pseudoportlandia Woodring, 1925 [type species Leda clara Guppy, 1873]. The specimen figured by del Río (2004b, fig. 12.6) as Pseudoportlandia glabra (Sowerby, 1846) also belongs to Ihering’s species and not to that of Sowerby, confirming our supposed generic placement of that species.
