[When referring to the Mount Holly series of Whittle (1894), please use informally. The practice of employing "series" for lithostratigraphic or lithodemic nomenclature is now regarded as improper (see ACSN, 1961, 1970; NACSN, 1983). The term "Series" is applied formally only to chronostratigraphic units.]
