We can see no valid grounds for maintaining B. tanakae and B. menabensis as separate species. Baculites tanakae differs from B. capensis by the fastigiate venter, and the predominance of obliquely or longitudinally elongated tubercles that are situated higher up on the flanks than in typical B. capensis.
