•outer and basal margins lirate-dentate; columella oblique, neither 
tortuous above nor entering the umbilicus; its front edge plain, 
■except a tooth at the base; umbilicus wide and deep, its margin 
crenate-clentate.* Height 8, diam. 14- mm. Not uncommon, 
beach, Holdfast Bay, Port Willunga. Xormanville, Corny Point, 
Venus Bay, Point Sinclair, St. Francis Island; and dredged to 30 
fathoms. Also Western Australia—Bunburv, Geraldton, Yallin-

Type in South Australian Museum. 
Slightly more depressed than M. plebejus , but much larger; 
umbilicus deeper, reaching to or beyond the junction of the 
penultimate and last whorls; the absence of trenchant tessel¬ 
lated sculpture and the equidistant granular lirae of the posterior 
area of the body whorl are distinctive characters.

angeli Tenison-Woods 1876). “The Many-keeled Clanculus.” 
Small, solid, orbicular, depressed, shining; pale chestnut, more or 
less spotted and clouded with brown; whorls four, keeled and 
lirate (four keels in last whorl); interstices lirate; keel at peri¬

lirate; umbilicus spirally striate with a white margin; mouth
