Abstract

Confusion has resulted from misidentification of Billings' Lower Cambrian trilobite species from Labrador and Vermont. A restudy of the type specimens and of specimens referred to the species by Walcott leads to considerable revision of the nomenclature. Twenty-five species are dealt with; 11 species are more sharply defined, and 2 new genera and 14 new species are instituted. Photographic illustrations of many of the forms are provided for the first time.
