GASTROPODA

" Ptychoris " see Gabb (1876b). Remarks: Gabb (1876b: 291) mentioned that Athleta purpuriformis (Forbes, 1846) and Athleta scrobiculata Stoliczka, 1867 –1868 might belong to a new genus, and Gabb informally suggested that it could possibly be named Ptychoris . Wenz (1943: 1322) erroneously reported that Gabb had officially named this genus, but Gabb did not describe it nor did he designate a type species.
