The small, rather thin shell has a depressedly conical shape and is widely umbilicate. Its colour is grey, turning to pink on the body whorl, a few scattered crimson dots on the larger ribs. The shell contains 4½ whorls. The spire is biangulate. The body whorl is angled at the shoulder, periphery and base. The sculpture consists of a well-developed spiral rib that girdles the periphery. Parted from this by broad interspaces runs a similar one above and another below. On the base are four smaller spirals followed by a larger granulate rib which borders the umbilicus. Within the broad and deep umbilicus continues a succession of granulose spirals. The flat subsutural shell is traversed by radial plications and the whole shell is overrun by dense, fine, radial threads. The simple aperture is subcircular.[2] DistributionThis marine species is endemic to Australia and occurs on the continental shelf off Queensland. References1. ^Marshall, B. (2014).
