Types. Holotype (MNHN-IM-2000-6014).

Type locality. Bay of Biscay , 48°37’N 09°52’W, 800–1050 m GoogleMaps .

Material examined. Holotype was covered with cristals. Mediterranean Sea , St. Lucia Bank, 400 m. 5 valves ( ZISP 2381 View Materials ), identified as Bathychiton biondii by Bruno Dell’Angelo.

Distribution. East Atlantic Ocean: Canary Islands (480–540 m), Bay of Biscay (800–1050 m), Gibraltar Strait (1378 m), Mediterranean Sea (250–400 m), Pleistocene, Calabria, Italy.

Remarks. Good descriptions were given by Kaas (1979) and by Kaas & Van Belle (1990) for C. platynomenus and by Dell’Angelo & Palazzi (1988) and Dell’Angelo & Smriglio (2001) for Bathychiton biondii . I agree with Kaas & Van Belle (1990) who synonymized B. biondii with C. platynomenus .

Connexochiton platynomenus differs from other species of the genus Connexochiton by having one transverse row of large globular spherules and longitudinal ribs on the dorsal scales.
