Type species: Trochus flindersi Fischer 1878. King George Sound, S.W.A.
Shell very narrowly perforate, conical, rather thick; whorls seven to eight, planulate, the first eroded, the succeeding whitish-ashen, radiated with narrow, close and flexuose blackish and violaceous lines; spirally cingulate; lirae six on the penultimate whorl; last whorl subangular, a little depressed above, dilated in the middle; base convex, ornamented with about eight lirae; aperture rhomboidal; lip simple; columella arcuate, truncate below.
Distribution: Southern Australia.
Remarks: The shell may be very narrowly or not perforate, when the umbilical area is marked by a depression. The smooth columella distinguishes the genus from Thalotia and Odontotrochus while the lack of the distinctive tooth separates it from Phasianotrochus and Cantharidus.
