Primary orifice occluded by sediment, details not known. No oral-spine bases. Frequently an avicularium adjacent to one corner of the peristome, mm long, elongate-oval with a rounded ros- trum that slopes steeply inwards to a narrow palate, the avicularium not as wide proximally: the preservation is inadequate to indicate whether there may have been a crossbar. Ovicells not present. Remarks. The generic attribution is uncertain. The species is most reminiscent of Recent Eschamides angela (Hutton, 1873) which also has a conspicuous scoop-like peristome. The origin of the.
