This page documents data for Bieler et al. (2014), such as genera and species attributed to that publication (including known misspellings, misidentifications, and other unavailable names) as well as taxonomic opinions, if available. Taxonomic opinions refer to uses of genera and species as valid and invalid in that work.

The MUSSEL Project Database is moving to a new server, with a new URL! The new address for this page will be: https://musselpdb.org/fmuotwaolcb/db.php?ty=publ&id=3622
