Description

This species was originally considered a variety of Solariella mutabilis (now a synonym of Spectamen mutabilis) with the following different characteristics: the shell with the peripheral and infraperipheral keel quite or nearly smooth (in one instance also the upper keel); the sculpture of the umbilicus more conspicuous. The finer sculpture of the upper part of the whorls and of the base, varies also in some degree, this last one so much, that it is nearly but never quite smooth.^[2]

Distribution

This marine species occurs off Timor, Indonesia.
