Material.— Two articulated sclerites with broken distal ends of lateral rays, and a number of disarticulated central and lateral rays from erratic boulders Me33 and 66. Figured specimens, ZPAL V. VI/36 S8, 10 ; 37S6.

Description.—Small sclerites with long, slender lateral rays (formula: 5+1) which slightly diverge from the basal plane. The outer surface of the ray has weak longitudinal striae. The basal facet is encircled by a distinct circular ridge. Protruding ridges well developed, but basal foramina and surrounding spherulitic structures partly covered with minerals.

Remarks.—A number of small and slender internal moulds (Fig. 6E, L), which do not expresse the characteristic feature associated with the basal facet of the ray, may also represent the species Ch. racemifundis .

Occurrence.—Early Cambrian (Atdabanian–Botomian) of the Kulpara Formation and Parara Limestone, Yorke Peninsula, Stansbury Basin and Ajax Limestone, Flinders Ranges, Arrowie Basin , South Australia; Middle Cambrian (Templetonian) of the Beetle Creek Formation, Georgina Basin, Queensland; allochthonous Early Cambrian (Botomian) boulders (Me33), King George Island, Antarctica.
