The upper part of Bed 3 of the type section of the Gorge Formation (Upper Cambrian) has yielded 15 kinds of trilobites, of which all but one [Plethometopus sp.] are previously described species. Four unnamed pygidia are also present. The fauna is characteristic of that described by P. E. Raymond in 1924, 1925, and 1937 from the lower zone (or Zone 1) of the same formation, which has been commonly referred to as the Hungaia magnifica fauna.
