Protoma mutabilis Sowerby — Dollfus et. al., 1903: 1 [plates published in Pereira da Costa , 1867: pl. 28, fig. 17]. Protoma (s.s.) gomesi Costa in Dollfus, Berkeley-Cotter & Gomes, 1903 — Glibert, 1962: 105 . Type material. We do not know the whereabouts of the type specimen(s). Discussion. A somewhat dubious and rarely reported species, which differs from A. carniolica and A. rotifera mainly in the absence of a pronounced keel at the adapical suture, the oblique suture, and the high whorls. Distribution. Only recorded from Portugal , where it co-occurs with other Allmonia species at the same Burdigalian, Serravallian and Tortonian localities ( Glibert 1962 ).
