Cribroelphidium Cushman & Brönniman 1948

Cribroelphidium sp. cf. C. excavatum ( Terquem 1875) ( Fig. 24 :19, 20)

Remarks. The distinct unkeeled periphery, inflated test with finely perforate walls, papillate ornament on the walls of the depressed sutures and sides of the sutural pits ( Fig. 24 :19, 20) indicates an affinity with C. excavatum . The acute peripheral edge is less common for this species however, and the small number of fragmentary tests available precludes a more definite species assignment.

Distribution within study area. This species was collected from site 8 in One Tree Lagoon 1 and site 8 in Heron Lagoon with no more than two specimens per site.
