Belleek Nautilus on Coral (Degenhardt reference number D131), with first black mark (1863-1890) and impressed "BELLEEK" and "Co FERMANAGH" underneath. Glazed white parian with mother of pearl lustre hints to nautilus shells and tinted pink (top), orange (below left), and untinted (below right) detailing. Height 8-1/2 inches (not 9-1/2 inches as reported in Richard Degenhardt's reference).

Note that the untinted example (above right) has had repairs to coral
and the edge of the nautilus shell, so the other two images
are more accurate representations of this item.
