(no illustration). Described by Czerniavsky from the Crimea region , Yalta bay , approximate coordinates 44.48°N 34.17°E , and Hursuf Bay , approximate coordinates 44.84°N 34.28°E . The combination is invalid on account of having four names (ICZN art. 45.5). I propose to assign the specimen to the subspecies H. alba subsp. albapontica nom.nov .
