Abstract
In the Eocene of Pakistan, India and Burma, two genera—Miscellanea and Pellatispira—have shown a remarkably stable and limited vertical range in the several areas in which representatives of these genera are found. Miscellanea, which is represented byM. miscella (d’Archiac and Haime),M. stampi (Davies), andM. meandrina (Carter), is confined to the Ranikot (Palæocene age) in all the areas examined so far, while Pellatispira, which is represented byP. cf. orbitoidea (Provale),P. cf. inflata Umbgrove,P. cf. madaraszi Von Hantken,P. cf. glabra Umbgrove, is found only in the very high Eocene (Upper Eocene) beds. Because of their very restricted vertical range these two genera are of considerable stratigraphic value.
