OCCURRENCE. — Middle Miocene: France, Spain, Austria, Poland (Baluk & Radwansky 1984). Late Miocene: Germany, Italy, Crete ( Moissette et al. 1993). Pliocene: UK, Netherlands, Sicily ( Pouyet & Moissette 1992), Algeria (Haddadi-Hamdane 1996), Crete (Marcopoulou-Diacantoni & Wuest 1999). Pleistocene: Sicily ( Rosso 1987), Rhodes (Moissette 2012). Recent: eastern Pacific ( Ecuador to northern Mexico), western and eastern Atlantic ( Brazil, Caribbean, Gabon, Azores, Madeira and Canary islands to southern Portugal), southern Mediterranean ( Rosso & Di Martino 2016). This warm-water species lives on sandy, more or less muddy bottoms at depths between 50 and 300 m ( Prenant & Bobin 1966). But it has also been found in much shallower (5-50 m) and much deeper waters (down to 860 m in the Sargasso Sea; Lagaaij 1963). Following Cadée (1979, 1981), C. canariensis seems however mostly a western Atlantic species.Records with this name must consequently be carefully checked, eliminating possible misidentifications (A. Rosso, personal communication).

REMARKS

Due to possible confusion with two other species of the same genus ( C. biporosa (Canu & Bassler, 1923) and C. vindobonensis Baluk & Radwanski, 1984 ) a systematic revision is needed. Cadée (1979) also created a new subspecies, Cupuladria canariensis cavernosa , for Mio-Pliocene European specimens with intermediate characteristics between C. biporosa and C. canariensis ( Cadée 1979, 1981).
