Notes. Following Kilburn (1977), authorship of this taxon has until now been ascribed to Anton (1838). However, Dillwyn (1817) had earlier validated Chemnitz’s name Trochus tigrinus, citing the original Chemnitzian figure. Although cited as a variety, this equates to a subspecies (ICZN Art. 45.6.4) and the name is thus available.

Priotrochus P. Fischer, 1879 . Type species (s.d. Wenz 1938): Trochus obscurus Wood, 1828 .
