This genus was named in 1915 by Walter Oliver after Tom Iredale (1880–1972), an English-born naturalist who lived mainly in Australia.[3]
Fossil species have been found in Pliocene strata of Italy and in Miocene strata of Indonesia; age range: 5.332 to 2.588 Ma.[4][5]
Description
The narrow, solid and turreted shell has a fusiform shape. The protoconch consists of 4 whorls, with a sinusigera apex. The shell is axially sculptured by numerous slender and continuous riblets. The aperture measures about a third of the length of the shell. The short siphonal canal is wide. The anal sinus is deep and broad, separated from the body whorl by a callosity. A brown band on the periphery is a usual feature.[3][6]
