Notes on Nomenclature

Recently changed to Vertambitus triangularis(Locard, 1898) in WoRMS. CLEMAM synonymise it with Verticordia sinuosa (Jeffreys 1882) but we have been unable to find published verification of the above synonymy. Specimens illustrated here are identical to Verticordia triangularis, whereas V. sinuosa is based on fragments.
