Three new species of Ammonicera from the Eastern Pacific coast of North <br />America, with redescriptions and comments on other species of Omalogyridae (Gastropoda, Heterobranchia)

Abstract

The family Omalogyridae comprises some of the smallest known marine snails. Like all micromolluscs, they have been historically neglected and are underrepresented in faunistic surveys. Based on a few focused studies of the family, 15 valid omalogyrid species were previously recognised in the Indian and Pacific Oceans.
