I know nothing of this species. The only reference I can find is:
"An even rarer [than B. lineata], endemic species, Bullina oblonga Sowerby, 1897, occasionally washes up between Port Alfred and the north coast of Natal. It is more elongate, with a higher spire, finer spiral sculpture and a colour pattern of numerous fine, axial, brownish-red lines, which are strengthened in places so that they also form two diffuse spiral zones: base with a spiral band of brownish-red." ...
