Talopena gloriola Iredale, 1929
Description: Shell width greater than height. Whorls rounded, occasionally weakly shouldered. Sculptured with weak, fine spiral riblets, about 10-15 on penultimate whorl. Umbilicus narrowly open; columellar callus thickened, with a tooth on umbilicus side, corresponding to a funicle in the umbilicus. Outer lip thin, smooth. Base rounded, sculptured as spire. Colour fawn, mottled with irregular axial brown streaks; several spiral ribs alternately white and brown. Interior nacreous.
Size: Up to 10 mm wide, 8 mm high.
Distribution: The Australian Museum holds specimens only from Port Stephens to Sydney, NSW. Cotton (1959, p. 102) reports it from NSW to south-western WA, but this needs confirmation.
Habitat: Known from beach shells, and down to 13 m.
