Discussion. This species was originally introduced by Eichwald (1851) as Cerithium connexum , which was also used on the plate captions of his atlas in Eichwald (1852). In his “Lethaea rossica” (1853), however, he changed the spelling into Cerithium convexum , which was adopted by later authors. Thus, Cerithium convexum is an incorrect subsequent spelling, which is also evident from the fact that Eichwald (1853: 158) again used Cerithium connexum . The lectotype, however, represents Potamides disjunctus (J. de C. Sowerby, 1832) .
