Abstract

Stricklandia davidsoni Billings, and upper Llandovery stricklandiid species with a peculiar chevron-like ornament, is made type species of a new genus Ehlersella. The new genus is known from Anticosti Island and Gaspe to Alabama and Kentucky and is believed to have been derived from the widespread Llandovery-age genus Stricklandia. 'Stricklandinia' norwoodi Foerste is redescribed from a large collection of well preserved specimens from the Red Mountain Formation of Alabama. Cardinal process lobes are developed on some of the latter specimens.
