Spectamen laeviorSpectamen laevior is a species of sea snail, a marine gastropod mollusk in the family Solariellidae.DescriptionThis species was originally considered a variety of Solariella mutabilis with the following different characteristics: the shell with the peripheral and infraperipheral keel quite or nearly smooth ; 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.DistributionThis marine species occurs off Timor, Indonesia.
