Ventral margin angular, dorsal margin arcuate, umbones strongly prosogyrate. « This interesting and very rare species, known and described by our friend Professor Seguenza after a fossil from the tertiary grounds of Messina, was found alive by Mr. Jeffreys in the catches obtained from the dredgings made by Captain Spratt on the southern coasts of Sicily; and it is worthy of observation, that the same species, just as Jeffreys writes, was fished in the seas of Japan. This genus was missing from the European Fauna, knowing only a few species from the Indian seas. » – Aradas & Benoit: Conchigliologia vivente marina della Sicilia e delle isole che la circondano, Catania 1870, p. 71. –Same spot. 7mm.
